History<br />
It started as a one-man, part-time operation<br />
making engine parts for himself and his hot rod buddies<br />
over 50 years ago. Today it has evolved into a multimillion<br />
dollar, multifaceted manufacturing operation, producing<br />
high performance engine equipment for a wide variety<br />
of applications, including cars, trucks, boats, tractors,<br />
motorcycles and antiques.<br />
<strong>Crower</strong> Cams and Equipment Company, Inc., is a<br />
leading producer of aftermarket camshafts and valve train<br />
components. But over the years <strong>Crower</strong> has developed a<br />
more diverse line of products. Today, <strong>Crower</strong> is the world’s<br />
largest manufacturer of aftermarket crankshafts and<br />
connecting rods, and the <strong>Crower</strong> line of clutches has been<br />
dominating the drag racing and tractor pulling series for<br />
nearly four decades.<br />
A young Bruce <strong>Crower</strong>, left, in his first shop in 1949 near Phoenix, Arizona.<br />
EARLY THOUGHTS<br />
Bruce <strong>Crower</strong>, president of <strong>Crower</strong> Cams, is the<br />
thinking man’s racer, saying, “People don’t think as much<br />
as they should. If you think hard enough, the answer will<br />
come.” Born in 1930 to a church going family in Phoenix,<br />
Arizona, he has been thinking about, and implementing<br />
ways to improve the internal combustion engine for nearly<br />
six decades.<br />
INTRODUCTION TO FAST MACHINES<br />
In 1949, a fast, 80 cubic inch Harley led to a 120 mph,<br />
300 cubic inch Merc-powered Deuce roadster that Bruce<br />
says was, “the first Arizona car to beat the bikes,” and his<br />
own successful speed shop near Phoenix, Arizona. Uncle<br />
Sam, however, had other plans and he was drafted for the<br />
Korean war.<br />
After 18 months on a ground crew in the Air National<br />
Guard, developing his mechanical skills in a machine shop<br />
at Luke Field Air Force Base, he followed his parents to<br />
San Diego and landed a job as a machinist at Paul Schiefer<br />
Clutches. All over California, especially at Paradise Mesa,<br />
people were burning up the quarter mile.<br />
THE CHRYSLER HEMI<br />
And despite the legendary Bean Bandits’ quantum<br />
leap from 120 to 140 mph with a Bruce <strong>Crower</strong> built<br />
engine, the flathead’s reign was over the day Chrysler<br />
introduced its OHV Hemi. Bruce was quick to realize the<br />
Hemi’s potential, and by 1954 he was shakin’ em up on the<br />
Bonneville salt flats with a 157 mph record breaking run<br />
behind the wheel of his Hemi-powered Hudson. Credited<br />
with being the first to top-mount a GMC blower, Bruce had<br />
fashioned his own intake manifold and a pulley system<br />
cast in coffee cans using old pistons as material.<br />
THE “U-FAB” INTAKE MANIFOLD<br />
The intake/blower combo was a success, and not<br />
only put Bruce in the record books but also in the manifold<br />
business. There followed the phenomenally successful<br />
<strong>Crower</strong> “U-Fab” do-it-yourself manifold. Consisting of two<br />
cylindrical runners joined with hoses and clamps, the<br />
“U-Fab” was designed to hold four, six or eight Stromberg<br />
carburetors.It was simple, inexpensive and extremely<br />
popular. “We sold thousands of them,” according to Bruce.<br />
The mega-popular “U-Fab”<br />
intake manifold.<br />
During high school, Bruce found that other hot<br />
rodders would buy parts that he made for his own ’32 Ford<br />
roadster. As new ideas came to mind, instead of making<br />
just one part for himself, he would make several at a time<br />
and sell them to his fellow hot rodders. It was simple<br />
arithmetic to see the profit of making thousands of such<br />
parts and selling them nationwide.<br />
1955 - THE BEGINNING OF CROWER EQUIPMENT CO.<br />
With $312 in the bank Bruce booked a sixth<br />
page ad in Hot Rod for $300. That one ad generated over<br />
$10,000 dollars worth of orders, and suddenly I was,<br />
“controlling my own destiny with my own two hands, and<br />
the harder I worked, the more money I made.” He worked<br />
until the wee hours of the morning assembling those kits,<br />
and finally hired his brother, Dave and eventual brother<br />
in-law, Loren in order to keep the production up with the<br />
demand. Thus the formation of <strong>Crower</strong>.<br />
Bruce ran 157 mph in this Hemi-powered Hudson.<br />

THE “GLIDE”<br />
Other speed merchants eventually followed his<br />
lead, tapping into <strong>Crower</strong>’s market share. But Bruce and<br />
the boys had been thinking ahead, this time about a double<br />
disc clutch first seen in a Fiat. <strong>Crower</strong> combined this<br />
technology with a Schiefer clutch and applied it towards<br />
drag racing and, once again, enjoyed another overnight<br />
success with the “<strong>Crower</strong>glide” centrifugal clutch. It quickly<br />
became the most popular clutch in drag racing.<br />
CAMSHAFT TECH-<br />
NOLOGY<br />
<strong>Crower</strong>, however,<br />
was already moving<br />
on, this time in the<br />
direction of cam<br />
technology where<br />
once again they An early model “<strong>Crower</strong>Glide” centrifugal clutch.<br />
took advantage of<br />
an industry in low gear. The industry’s shortcomings have<br />
always provided the impetus for <strong>Crower</strong>’s ideas. Only the<br />
experiences at the Indianapolis 500 Brickyard have caused<br />
him to reevaluate his direction.<br />
Bruce built this outside port<br />
design V8 Chevy to improve<br />
breathing efficiency.<br />

over 200 people in our<br />
new 110,000 sq ft building.<br />
Utilizing the latest in computer<br />
assisted design (CAD),<br />
<strong>Crower</strong> engineers render multidimensional<br />
blueprints that are then<br />
downloaded into one of <strong>Crower</strong>’s state-of-the-art CNC<br />
machining centers. This allows more flexibility, with tighter<br />
tolerances, and gives the customer more choices. <strong>Crower</strong><br />
offers over 10 different styles of steel billet connecting rods<br />
and five different crank designs for the small block Chevrolet<br />
depending on the customer’s particular application,<br />
rpm range and budget.<br />
THE INDY EXPERIENCE<br />
In 1954, Bruce <strong>Crower</strong> was invited to<br />
work on the Offy-powered Dean Van Lines<br />
Indianapolis racing car with Jimmy Bryan. They<br />
qualified on the front row and finished second.<br />
Six years later, working on Jim Rathmann’s<br />
team, all of their hard work paid off as they<br />
went on to win the 1960 Indy 500. He went<br />
on to win again as a member of Graham Hill’s<br />
team, and again in 1967 as part of the A.J. Foyt<br />
team.<br />
Subsequent years saw <strong>Crower</strong> cars<br />
equipped with engines as diverse as a downsized<br />
small-block Chevy and a custom designed flat-eight<br />
with Cosworth heads, which received the 1977 SAE “Louis<br />
Schwitzer Award” for race car design. But over the years, in<br />
order to remain competitive, teams started preparing year<br />
around for the race, and Bruce decided that his time and<br />
money would be better<br />
spent investing in<br />
his own business in<br />
the area of high<br />
performance<br />
engine parts<br />
and engine<br />
research.<br />
Bruce, third from right, was on Jim Rathmann’s<br />
1960 Indy winning crew with Smokey Yunick.<br />
This downsized 209<br />
c.i.d. stock block<br />
Chevy produced over<br />
850hp at Indy.<br />
<strong>Crower</strong>’s new, state-of-the-art of the art building<br />
features 110,000 sq ft and over 100 CNC machining<br />
centers. The goal will be to dramatically reduce<br />
leadtimes on all <strong>Crower</strong> products.<br />

History<br />
RESEARCH & DEVELOPMENT<br />
Although Bruce <strong>Crower</strong> is<br />
no longer involved in the day-to-day<br />
manufacturing operation, he spends his time<br />
designing and developing new products at the<br />
company’s research and development facility<br />
located at his Jamul ranch. This R&D facility houses<br />
a complete machine shop and a fully operational,<br />
computer controlled Heenan-Froude engine<br />
dynamometer, capable of generating high levels<br />
of horsepower and torque on just about any type<br />
of engine. Before <strong>Crower</strong> introduces a new product<br />
to the market, you can be sure it has undergone a<br />
rigorous cycle of testing under dyno simulated racing<br />
conditions. Each<br />
<strong>Crower</strong> product<br />
is then evaluated<br />
for maximum<br />
horsepower and<br />
torque figures,<br />
as well as rpm<br />
specifications to<br />
insure product<br />
reliability.<br />
This 700hp straight-8 Nash was put in<br />
a Model-T roadster.<br />
THE BONNEVILLE SALT FLATS<br />
In addition to product testing and development, both<br />
of <strong>Crower</strong>’s Bonneville race cars were completely<br />
designed and constructed at the Jamul facility.<br />
A 1927 Model-T roadster equipped with a 700hp<br />
1931 straight-8 Nash engine, and a state-of-theart<br />
streamliner powered by a turbocharged small<br />
block Chevy and a pair of prototype <strong>Crower</strong> 4-valve<br />
cylinder heads. He first touted the idea of a four-valve<br />
production head for the small-block Chevy back in<br />
1965 after inventing a head with an inlet port on the<br />
same plane as the exhaust port. Chevy engineers<br />
were so impressed they had prototypes drawn and<br />
cast within 30 days. Unfortunately, the various race<br />
sanctioning bodies indicated that they would have to<br />
ban it because it would have given certain racers an<br />
unfair advantage. The streamliner, however, is in the<br />
Unlimited Class and with the help of the heads and<br />
some other radical design solutions, it is projected<br />
to run over 440 mph at 1150 horsepower on the<br />
Bonneville salt flats.<br />
The streamliner’s pair of 4-valve cylinder heads were handcrafted by Bruce.<br />
RECOGNIZING HIS DEDICATION<br />
In recognition of <strong>Crower</strong>’s innovative products for<br />
drag racing, Bruce <strong>Crower</strong> was inducted into the Drag<br />
Racing Hall of Fame located in Florida. An honor and<br />
privilege that is the direct result of his hard work and<br />
dedication to the industry that he loves so much.<br />
USING QUALITY, AMERICAN MADE MATERIALS<br />
The secret to <strong>Crower</strong>’s lasting success, according to<br />
Dave <strong>Crower</strong>, vice president and general manager<br />
of <strong>Crower</strong>, is that basically “we make what people<br />
ask for. We do it with better quality than anyone<br />
else, plus we do it lighter, which is the key to quicker<br />
elapsed times.” Not one to compromise the strength<br />
and integrity of <strong>Crower</strong>’s products, <strong>Crower</strong> uses USA<br />
milled materials in its manufacturing. Although<br />
cheaper products can be imported from other<br />
countries, the <strong>Crower</strong> philosophy has always been<br />
that “If a product is made right the first time, using<br />
the highest quality materials and the latest<br />
production methods, it will perform flawlessly to it’s<br />
intended ability.”<br />
<strong>Crower</strong>’s custom built<br />
streamliner is powered by a<br />
turbocharged SB Chevy<br />
with 4-valve heads.<br />

Camshaft Selection<br />
VEHICLE PACKAGE<br />
It is the complete vehicle package that will determine how well your vehicle satisfies your<br />
performance preference.<br />
By complete vehicle package we mean the interaction of all a vehicle’s components and<br />
subsystems, including the engine and its related parts (such as the carburetor, intake manifold,<br />
exhaust system, camshaft and ignition), the transmission, rear end gears, wheel and tire<br />
combinations and diameters and suspension pieces. All of these components must work in<br />
unison to produce the desired performance results.<br />
RPM POWER RANGE<br />
Before thumbing through the collection of profiles listed on the following pages you will need<br />
to formulate a definite idea of your motoring requirements. Doing so will dictate what rpm<br />
power range you will be operating in most often (see Fig. 1). Because camshaft selection as well<br />
as carburetion, manifold choice and gearing are based on it, knowing your rpm power range is<br />
the key to building a successful vehicle package.<br />
Be realistic when examining your driving style, the vehicle’s present engine/drive train<br />
components and your pocket book. Be sure you can afford to purchase all of the components<br />
necessary to complete the desired vehicle package at your performance level. Remember,<br />
the further from stock you deviate in the engine department, the more modifications will be<br />
required elsewhere in the vehicle.<br />
Refer to the five performance levels listed below for an idea of the components required to<br />
produce a successful vehicle package at the performance level you desire.<br />
Approximate RPM Power Range:<br />
Hydraulic camshafts - Idle to 3500 / Redline: 4500.<br />
Solid camshafts - 1000 to 4000 / Redline: 5000.<br />
LEVEL 1 CAMS<br />
MILEAGE & TORQUE<br />
Level 1 indicates a good stock replacement camshaft. These profiles are designed to enhance<br />
throttle response and low end torque in vans, trucks, passenger cars and mild marine<br />
applications while delivering fuel efficient motoring. High vacuum, smooth idle and maximum<br />
efficiency are characteristics of these cams. Stock or small cfm carburetor, small diameter<br />
tube headers and dual exhaust are recommended for maximum benefit. Intended for stock or<br />
near-stock engines and drive trains, 8.5:1 compression, 2.70 to 3.25 ring and pinion, automatic<br />
transmission with stock converter or four-speed manual transmission.<br />
Approximate RPM Power Range:<br />
Hydraulic camshafts - 1500 to 4000 / Redline: 5500.<br />
Solid camshafts - 2000 to 5000 / Redline: 6000.<br />
LEVEL 2 CAMS<br />
MILEAGE & POWER<br />
Level 2 profiles are for individuals that require more power and an extended rpm range. Works<br />
well with stock or near-stock engines and drive trains. These camshafts provide excellent low<br />
end and mid-range power for spirited street and off road driving and mild marine applications.<br />
Modifications that should accompany installation of these cams include small diameter tube<br />
headers, low restriction dual exhaust, aftermarket manifold, increased cfm carburetor and<br />
reworked or performance ignition. Increased compression (9.5:1) is recommended for maximum<br />
output. Aftermarket torque converter with slightly higher stall speed is recommended because<br />
stock factory converters do not allow the engine to provide adequate idle speed and off idle<br />
performance. Works well with four-speed manual transmission. Designed for lightly modified<br />
street engines.<br />

Camshaft Selection<br />
LEVEL 3 CAMS<br />
HIGH<br />
PERFORMANCE<br />
Approximate RPM Power Range:<br />
Hydraulic camshafts - 1800 to 4500 / Redline: 6000.<br />
Solid camshafts - 2200 to 6000 / Redline: 7000.<br />
Hydraulic roller camshafts - 2000 to 4700 / Redline: 6250.<br />
Level 3 camshafts are designed for moderately modified engines. Intended for performance hot<br />
street/strip and performance marine applications, these profiles have a moderate lope at idle and<br />
offer an extended rpm range with emphasis on upper bottom to top end power and a strong midrange.<br />
These higher lift, longer duration camshafts demand close attention to rear end gearing and<br />
tire diameter combinations. The secret here is to pick a ring and pinion gear set and tire diameter<br />
that keeps the engine in its optimum rpm power range (see Fig. 1). These profiles perform well<br />
with four-speed manual transmissions or automatic transmissions if a high stall torque converter is<br />
employed. Headers, dual exhaust, larger than stock carburetor, performance manifold and increased<br />
compression (9.5:1 to 10.5:1) are required. Mild porting and larger valves will improve performance.<br />
LEVEL 4 CAMS<br />
ULTRA<br />
PERFORMANCE<br />
Approximate RPM Power Range:<br />
Hydraulic camshafts - 2000 to 6000 / Redline: 6500.<br />
Solid camshafts - 2500 to 6500 / Redline: 7500.<br />
Hydraulic roller camshafts - 2200 to 5000 / Redline: 6500.<br />
Level 4 camshafts are designed for heavily modified engines. They have a definite lope at idle and<br />
are best suited for dual purpose hot street/drag strip, hot marine and oval track applications. These<br />
grinds exhibit strong mid-range to top end torque and horsepower. Headers, dual exhaust, large<br />
cfm carburetor, performance ignition and increased compression of 10.25:1 and above are required.<br />
Cylinder head modifications would be beneficial. Use with standard manual transmission or<br />
automatic with high stall torque converter. Again, close attention to proper ring and pinion and tire<br />
diameter selection is imperative.<br />
LEVEL 5 CAMS<br />
COMPETITION/<br />
RACE ONLY<br />
Level 5 camshafts are designed for fully prepared, high compression, all-out racing engines and<br />
chassis. Extensive cylinder head modification, bigger valves, lightweight valve train, titanium valves,<br />
maximum flow carburetion or fuel injection, racing gas, alky or nitro, magneto or electronic ignition,<br />
performance rod and crank assembly and increased engine clearances are required for maximum<br />
benefit.<br />
The wide selection of level 5 profiles enable the experienced engine builder to choose the proper<br />
camshaft for his particular application, whether it be drag racing, oval track competition, tractor<br />
pulling or performance marine. If you are uncertain as to which cam profile best suits your needs,<br />
please contact our technical support staff at 619-422-1191.<br />

BE SMART! <strong>Crower</strong> performance camshafts feature high lift, fast action features that<br />
can cause stock or other aftermarket valve train components to fail. Be sure to use a<br />
<strong>Crower</strong> engineered kit to avoid possible damage.<br />

CROWER CAM BREAK-IN PROCEDURE<br />
This applies to all hydraulic and solid lifter camshafts using higher than<br />
stock spring pressure:<br />
• Do not use block restrictors in the oil galleys. This severely limits oil flow<br />
to the cam, lifters and overhead.<br />
• Break-in cam and lifters with low pressure springs only. Do not exceed 225<br />
to 250 lbs open pressure.<br />
• During break-in run engine for 35 to 45 minutes and vary rpm from<br />
2000 to 3000.<br />
• For break-in procedure <strong>Crower</strong> recommends 10W/30 motor oil. Heavier weight oils<br />
do not cold flow.<br />
• Do not use synthetic oils during break-in period.<br />
• For further information, please refer to the <strong>Crower</strong> Installation booklet that accompanies the camshaft.<br />
For technical support call 619-661-6477 • Some products listed are not legal for sale or use on emission controlled motor vehicles<br />

Level 1 - These cams are designed to enhance<br />
throttle response and low-end torque in vans,<br />
trucks and passenger cars while delivering fuel<br />
efficient motoring. High vacuum, smooth idle<br />
and maximum fuel efficiency are characteristic to<br />
these profiles. Stock or small cfm carburetor, small<br />
diameter tube headers, dual exhaust, and ignition<br />
rework are recommended for maximum benefit.<br />
Intended for low compression engines operating in<br />
the “economy zone.”<br />

POWER COMPU-PRO / Performance Level 2<br />
- These cams provide excellent low end and midrange<br />
power and extended rpm range for spirited<br />
street and off-road driving. A perfect combination<br />
of mileage and power. Modifications should include<br />
small diameter tube headers, low restriction<br />
dual exhaust, aftermarket manifold, increased<br />
cfm carburetor and reworked or performance<br />
ignition. Increase in compression ratio to 9.5:1 is<br />
recommended for maximum output.<br />
Works well with automatic transmission or<br />
4-speed.<br />
RPM Power Range: 1300-1500 to 4000-4200 /<br />

* These cid engines (383, 406) require a smaller base circle for 3.750" or larger stroke cranks. Add an “S” at the end of<br />
desired cam part number (example: 00275S) if smaller base circle is desired.<br />
Note: Small base circle cams are available if using 3.750" stroke and 350 style rods. Specify “S” after part<br />
number. If using 400 style or stroker rods the above base circle will work.<br />

For severe duty applications, <strong>Crower</strong> offers a high-lube “CamSaver” lifter that channels more<br />
oil to the cam lobe and lifter surface. Specify X3 after corresponding component kit.<br />
Spring pressure:<br />
68301X1-16 Seat: 1.700" @ 105 lbs / Nose: 1.250" @ 274 lbs / Coil bind: 1.130" (Stock O.D., no machine work).<br />
68311X1-16 Seat: 1.750" @ 120 lbs / Nose: 1.250" @ 389 lbs / Coil bind: 1.070" (Stock O.D., no machine work).<br />
68390X3-16 Seat: 1.800" @ 116 lbs / Nose: 1.250" @ 355 lbs / Coil bind: 1.110" (Machine work, use cutter 68985*).<br />
* Machine work required, specify 11⁄32 pilot shaft when ordering.<br />
Note: If using 3.750" stroke or above cranks, contact <strong>Crower</strong> for smaller base circle camshafts for more<br />
rod clearance.<br />
BE SMART! <strong>Crower</strong> performance camshafts feature high lift, fast action features that can cause stock or other<br />
aftermarket valve train components to fail. Be sure to use a <strong>Crower</strong> engineered kit to avoid possible damage.<br />
CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance at<br />
full lift (minimum .050").<br />
LIFT RULE <strong>CAMSHAFTS</strong>: <strong>Crower</strong> has a complete line of camshafts that will satisfy any max lift requirement.<br />

See pg. 136 Timing gear kit<br />
Note: If using longer than stock valves you<br />
may require spring and retainer modifications.<br />
See specs or contact <strong>Crower</strong>.<br />
REMEMBER! Increasing rocker ratio on intake<br />
(1.6) will make the cam approximately<br />
3° duration and .030" more lift.<br />
HIGH RPM! <strong>Crower</strong> highly recommends the<br />
use of rollerized rockers. See rocker section for<br />
ratios and stud diameters.<br />
These camshafts will work with the following<br />
carburetor sizes: 350 (210 cfm), 390 (410 cfm),<br />
500 (350 cfm).<br />
If you can supply cylinder head flow data,<br />
engine specs, operating power ranges and<br />
exhaust manifold configurations we will be<br />
able to grind you a camshaft that is far superior<br />
than any other brand currently available.<br />
clearance. Valve timing events are available online at: www.crower.com/valvtime.html<br />

*86781-16 and 86767-16 retainers require Super 7° keepers. Titanium valves required to achieve high rpm.<br />
Due to the wide variety of valve train combinations (i.e. lifter bore diameters, offsets, valve lengths, installed<br />
heights, etc...), we highly recommend that you contact <strong>Crower</strong> for your specific valve train needs.<br />
HIPPO Note: For severe duty roller lifter applications, we highly recommend using our roller lifters with<br />
Hippo “High Pressure Pin Oiling”. Specify “H” in the part number.<br />
Ex. 66290X874H-16<br />
Note: When ordering a .930" - .950" base circle cams for 3.750" or larger stroker cranks, add an “S” at the<br />
end of the part number. Example: 00432S. For strokes of 3.900" or larger contact <strong>Crower</strong> for .850" base<br />
circle camshafts.<br />
HIGH RPM! With today’s high engine rpm and increased rocker ratios, valve train life is extremely critical.<br />
Increased spring pressures are mandatory for insuring reliable valve train life. Contact <strong>Crower</strong>’s technical assistance<br />
department for proper high rpm recommendations.<br />
INTEGRAL CAST IRON GEAR OPTION: Premium 8620 steel billet, copper plated cam cores with integral cast<br />
iron cam gear are available from <strong>Crower</strong> on a special order basis (specify part number 00050). Valve timing<br />
events are available online at: www.crower.com/valvtime.html<br />

Due to the wide variety of valve train combinations (i.e. lifter bore diameters, offsets, valve lengths, installed heights, etc...), we highly recommend<br />
that you contact <strong>Crower</strong> for your specific valve train needs.<br />
Note: When ordering a .930" - .950" base circle cams for 3.750" or larger stroker cranks, add an “S” at the end of the part number. Example: 00432S.<br />
For strokes of 3.900" or larger contact <strong>Crower</strong> for .850" base circle camshafts.<br />
HIGH RPM! With today’s high engine rpm and increased rocker ratios, valve train life is extremely critical. Increased spring pressures are mandatory<br />
for insuring reliable valve train life. Contact <strong>Crower</strong>’s technical assistance department for proper high rpm recommendations.<br />
INTEGRAL CAST IRON GEAR OPTION: Premium 8620 steel billet, copper plated cam cores with integral cast iron cam gear are available from<br />
<strong>Crower</strong> on a special order basis (specify part number 00050). Valve timing events are available online at: www.crower.com/valvtime.html<br />
HIPPO Note: For severe duty roller lifter applications, we highly recommend using our roller lifters with Hippo “High Pressure Pin Oiling”. Specify<br />
“H” in the part number.<br />

CROWER CAM BREAK-IN PROCEDURE<br />
This applies to all hydraulic and solid lifter camshafts using higher than stock spring pressure:<br />
•Do not use block restrictors in the oil galleys. This severely limits oil flow to the<br />
cam, lifters and overhead.<br />
•Break-in cam and lifters with low pressure springs only. Do not exceed 225 to<br />
250 lbs open pressure.<br />
•During break-in run engine for 35 to 45 minutes and vary rpm from 2000 to 3000.<br />
•Recommend adding Engine Oil Supplement (EOS) or equivalent to fortify oil.<br />
Use <strong>Crower</strong> #86084.<br />
•For break-in procedure only, <strong>Crower</strong> recommends 10W/30 motor oil. Heavier weight<br />
oils do not cold flow.<br />
•Do not use synthetic oils during break-in period.<br />

Performance Level)<br />
MILEAGE COMPU-PRO / Performance Level 1 - These cams are designed<br />
to enhance throttle response and low-end torque in vans, trucks and<br />
passenger cars while delivering fuel efficient motoring. High vacuum,<br />
smooth idle and maximum fuel efficiency are characteristic to these<br />
profiles. Stock or small cfm carburetor, small diameter tube headers, dual<br />
exhaust, and ignition rework are recommended for maximum benefit.<br />
Intended for low compression engines operating in the “economy zone.”<br />
RPM Power Range: Idle to 3500-3700 / Redline: 4500 plus.<br />

POWER COMPU-PRO / Performance Level 2 - These cams provide<br />
excellent low end and mid-range power and extended rpm range for<br />
spirited street and off-road driving. A perfect combination of mileage and<br />
power. Modifications should include small diameter tube headers, low<br />
restriction dual exhaust, aftermarket manifold, increased cfm carburetor<br />
and reworked or performance ignition. Increase in compression ratio to<br />
9.5:1 is recommended for maximum output.<br />
Works well with automatic transmission or 4-speed.<br />

HIGH PERFORMANCE COMPU-PRO / Performance Level 3 - Intended<br />
for the performance oriented hot street application. These cams offer an<br />
extended rpm range with emphasis on upper bottom to top end power<br />
(strong mid-range). Performance gears, headers, dual exhaust, larger than<br />
stock cfm carburetor, performance manifold and increased compression<br />
(9.5:1 to 10.5:1) are required. Works well with automatic transmission if<br />
matched with proper ring and pinion gears and/or high stall converter.<br />

ULTRA-PERFORMANCE COMPU-PRO / Performance Level 4 - The<br />
following grinds are best suited for dual purpose hot street/drag strip<br />
situations. These cams exhibit strong mid-range and top end torque and<br />
horsepower. Headers, dual exhaust, larger cfm carburetor, performance<br />
ignition and 11:1 compression are a must. Cylinder head modifications<br />
would be beneficial. Use with standard transmission or automatic with<br />
high stall converter. Low gearing a must.<br />

BE SMART! <strong>Crower</strong> performance camshafts feature high lift, fast action features that can cause stock or other aftermarket valve train components to fail.<br />
Be sure to use a <strong>Crower</strong> engineered kit to avoid possible damage. CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve<br />
guide clearance at full lift (minimum .050"). Do not exceed .550" gross lift using stock rocker arms.<br />

STAINLESS STEEL VALVES<br />
Made from the highest grade stainless steel, this new <strong>Crower</strong> valve is a must<br />
for high horsepower, high boost and high rpm applications. The exclusive “Pro<br />
Flo” head design delivers a significant increase in cylinder head flow figures,<br />
while the tip area is hardened to RC50, including past the critical keeper groove<br />
area for added strength. Fully CNC machined and swirl polished to insure that<br />
you will get the best performance valve available on the market. Choose from<br />
standard and 1mm oversize. Titanium valves also available.<br />

figures, while the tip area is hardened to RC50,<br />
including past the critical keeper groove area<br />
for added strength. Fully CNC machined and<br />
swirl polished to insure that you will get the<br />
best performance valve available on the market.<br />

<strong>Crower</strong>'s new cam sprockets are made from premium 6061-T6<br />
billet aluminum and incorporate a four bolt ARP® fastening<br />
system to prevent the slippage found in other brands. For the<br />
ultimate tuner, <strong>Crower</strong> sprockets feature 5/16" diameter, 12<br />
point ARP® fasteners with a hardened washer to prevent galling<br />
and stripping. The lightweight design reduces unwanted<br />
harmonics which could cause valve train failure.<br />

STAINLESS STEEL VALVES<br />
Made from the highest grade stainless steel,<br />
this new <strong>Crower</strong> valve is a must for high horsepower,<br />
high boost and high rpm applications.<br />
The exclusive “Pro Flo” head design delivers<br />
a significant increase in cylinder head flow<br />
figures, while the tip area is hardened to RC50,<br />
including past the critical keeper groove area<br />
for added strength. Fully CNC machined and<br />
swirl polished to insure that you will get the<br />
best performance valve available on the market.<br />
Choose from standard and 1mm oversize.<br />
Titanium valves also available.<br />

CUSTOM GROUND SOLID - Special order solid lifter camshaft ground<br />
to your specifications. Call our technical support staff for personalized<br />
camshaft assistance.<br />
Note: The above solid profiles are ground with a smaller base circle than stock. If using stock length valves, you must use .055" thick lash caps (86126-8) in kit below.<br />
Check follower geometry with Dykem hi-spot blue or any other non-drying compound and adjust valve length accordingly (see diagram 1). Duration numbers @ .050"<br />

Note: If your installed height does not fall withtin these dimensions, contact<br />
<strong>Crower</strong> for a recommendation.<br />
* Machine work required, specify 11⁄32 pilot shaft when ordering.<br />
Note: If using Boss heads contact the <strong>Crower</strong> for special spring and retainer recommendations.<br />
Boss 302 engines employ a 1.73 rocker ratio, so the gross lifts<br />
will change for the Boss 302. To figure the correct gross lift for Boss 302 heads<br />
divide the gross lift listed by 1.6 (lobe lift) then multiply the lobe lift by 1.73 (Boss<br />
302 rocker ratio).<br />
Note: Camshafts for 289/302 cid engines can be used in 351W engines by changing<br />
the firing order to 1-5-4-2-6-3-7-8.<br />
Some early Ford heads use 5⁄16 valve stems. Please specify when ordering as the<br />
above kits are designed for 11⁄32 stems.<br />
CAUTION! When using high lift cams pay close attention to retainer, oil seal and<br />
valve guide clearance at full lift (minimum .050"). Valve timing events are available<br />
online at: www.crower.com/valvtime.html<br />

Note: If keeper height is longer or shorter than correct height (± .050" tolerance),<br />
contact <strong>Crower</strong> for a recommendation.<br />
Note: If using Boss heads contact the factory for special spring and retainer<br />
recommendations. Boss 302 engines employ a 1.73 rocker ratio, so the gross<br />
lifts will change for the Boss 302. To figure the correct gross lift for Boss 302<br />
heads divide the gross lift listed by 1.6 (lobe lift) then multiply the lobe lift by<br />
1.73 (Boss 302 rocker ratio).<br />
Note: Camshafts for 289/302 cid engines can be used in 351W engines by<br />
changing the firing order to 1-5-4-2-6-3-7-8.<br />
Some early Ford heads use 5⁄16 valve stems. Please specify when ordering as<br />
the above kits are designed for 11⁄32 stems.<br />
CAUTION! When using high lift cams pay close attention to retainer, oil seal<br />
and valve guide clearance at full lift (minimum .050"). Valve timing events are<br />

(Machine work required, use 68985 cutter & 68972 pilot).<br />
Note: If using Boss heads contact the factory for special spring and retainer recommendations. Boss<br />
302 engines employ a 1.73 rocker ratio, so the gross lifts will change for the Boss 302. To figure the<br />
correct gross lift for Boss 302 heads divide the gross lift listed by 1.6 (lobe lift) then multiply the lobe<br />
lift by 1.73 (Boss 302 rocker ratio).<br />
Note: Camshafts for 289/302 cid engines can be used in 351W engines by changing the firing order<br />
to 1-5-4-2-6-3-7-8.<br />
Some early Ford heads use 5⁄16 valve stems. Please specify when ordering as the above kits are<br />
designed for 11⁄32 stems.<br />
CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance<br />
at full lift (minimum .050").<br />

ADJUSTABLE SPROCKETS<br />
<strong>Crower</strong>'s new cam sprockets are<br />
made from premium 6061-T6<br />
billet aluminum and incorporate<br />
a four bolt ARP® fastening<br />
system to prevent the slippage<br />
found in other brands. For the<br />
ultimate tuner, <strong>Crower</strong> sprockets<br />
feature 5/16" diameter, 12 point<br />
ARP® fasteners with a hardened<br />
washer to prevent galling and<br />
stripping. The lightweight<br />
design (367g) reduces unwanted<br />
harmonics which could cause<br />
valve train failure.<br />
REMEMBER!<br />

ADJUSTABLE SPROCKETS<br />
<strong>Crower</strong>'s new cam sprockets are made from premium<br />
6061-T6 billet aluminum and incorporate a four<br />
bolt ARP® fastening system to prevent the slippage<br />
found in other brands. For the ultimate tuner, <strong>Crower</strong><br />
sprockets feature 5/16" diameter, 12 point ARP® fasteners<br />
with a hardened washer to prevent galling and<br />
stripping. The lightweight design reduces unwanted<br />
harmonics which could cause valve train failure.<br />

over 80 different combinations of proven<br />
drag racing cam profiles and lobe center<br />
configurations. So rather than list each<br />
profile and lobe center, we felt that it<br />
would be more beneficial to encourage<br />
you to call our experienced technical<br />
support staff with your accumulated data<br />
and specifications. In a joint effort, that<br />
will be kept in the strictest of confidence,<br />
we will formulate the right combination<br />
of intake and exhaust lobe characteristics<br />
designed specifically for your application.<br />
We are currently involved with some of<br />
the top racers and engine builders and are<br />

STAINLESS STEEL VALVES<br />
Made from the highest grade stainless steel, this new<br />
<strong>Crower</strong> valve is a must for high horsepower, high boost and<br />
high rpm applications. The exclusive “Pro Flo” head design<br />
delivers a significant increase in cylinder head flow figures,<br />
while the tip area is hardened to RC50, including past the<br />
critical keeper groove area for added strength. Fully CNC<br />
machined and swirl polished to insure that you will get the<br />

Note: For lifts over .480" pushrods 70049-16 or 70050-16 are required. All solid lifter profiles require<br />
adjustable pushrods.<br />
Non-adjustable pushrods can be used if you have proper lifter preload (.050" off snap-ring). Custom<br />
length pushrods are available from <strong>Crower</strong> to achieve proper lifter preload. Customer must furnish<br />
accurate pushrod length. In order to assist in proper preload measurement, <strong>Crower</strong> offers an<br />
adjustable checking pushrod.<br />
Note: 1964-66 Oldsmobile blocks require 45° cam cores and cannot be interchanged with late model<br />
(39°) cam cores. Early model 45° camshafts are available on a special order basis. Customer must<br />
furnish lifter bore diameter when ordering.<br />

A. Lifter 66962-16 is a special high oil band tappet with high pushrod seat. It is not a Chevrolet solid lifter.<br />
Note: Non-adjustable pushrods can be used if you have proper lifter preload (.050" off snap-ring). Custom length pushrods are available<br />
from <strong>Crower</strong> to achieve proper lifter preload. Customer must furnish accurate pushrod length.<br />
CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance at full lift (minimum .050").<br />
Note: The above kit will not work if using Pontiac heads with 1.65:1 rocker ratio (springs are too short). Contact <strong>Crower</strong> for special spring<br />
and retainer combination. See diagram 2.<br />
Note: For proper valve adjustment on solid lifter profiles, <strong>Crower</strong> “Sure-Lock” rocker nuts (86053) must be used.<br />

CAMSHAFT REGRINDS<br />
If you’re lacking performance, send <strong>Crower</strong> your used or damaged<br />
camshaft for complete lobe analysis and regrinding or repair. Cams will<br />
be straightened and then checked-out (sample shown above) to establish<br />
original specs. A <strong>Crower</strong> technician will analyze all of the data and, based<br />
on your performance parameters, regrind your cam to desired specs.<br />
Description<br />
#1 TOURING PROFILE (250F)<br />
(Solid Lifter) Improves entire rpm range from 1000 to 6000.<br />
Smooth idle. Stock applications with no more than 10.5:1<br />
compression.<br />
#2 RALLY SPORT PROFILE (264F)<br />
(Solid Lifter) Slight lope at idle. Improves rpm range from 1500 to<br />
6500. Greatly improves high gear acceleration for passing and hills.<br />
#3 SLALOM/AUTOCROSS PROFILE (270F)<br />
(Solid Lifter) Slight lope at idle, but smooth into the throttle. Improves<br />
rpm range from 2000 to 6700 plus. More power for passing and hills.<br />
#4 CLUB RACER PROFILE (284F)<br />
(Solid Lifter) Racy lope at idle. Extends rpm range from 2500 to 6500<br />
with redline at 7100 plus. Increased compression, valve pocketing<br />
in combustion chamber and added carburetion will enhance total<br />
power.<br />
#5 COMPETITION PROFILE (290F)<br />
(Solid Lifter) Race only. Very rough idle, especially with added<br />
carburetion. Higher compression pistons or head milling advised as<br />
peak horsepower develops in 5500 to 6500 rpm range.<br />
#6 ROAD RACING PROFILE (304F)<br />
(Solid Lifter) Race only. Requires extensive modifications like 13:1<br />
compression, grouped exhaust system, individual carburetion, inlet<br />
valve pocketing and engine balance. Rpm range from 4500 to 8000.<br />

Using <strong>Crower</strong> camshaft bushings is<br />
the easy way to “tune” your camshaft<br />
timing. You’ll receive five advance or<br />
retard bushings that are individually<br />
stamped to display amounts advance/retard<br />
in cam degrees (0°, 1°,<br />
2°, 3°, 4°). Features a shouldered lip<br />
that retains the bushing and eliminates<br />

LIGHTWEIGHT<br />
FUEL PUMP PUSHROD<br />
The <strong>Crower</strong> fuel pump pushrod is<br />
manufactured from lightweight steel<br />
tubing that is heat-treated for added<br />
strength. The bronze tip insures proper<br />
surface mating with the fuel pump<br />
eccentric lobe on 8620 steel billet<br />
camshafts. This surface compatibility<br />
eliminates the wear problems associated<br />
with stock designs. For cast iron<br />
hydraulic and solid cams we offer a<br />
lightweight model with a steel tip at<br />
each end to protect against wear.<br />

CAM THRUST PLUGS<br />
Roller cam lobes are ground flat,<br />
without the taper found in hydraulic<br />

sits between the front of the timing<br />
gear and the back of the front cover<br />
and prevents forward cam travel and<br />
ignition flutter in roller grinds. Available<br />
in choice of two styles: phenolic<br />
(non-galling material) or fully rollerized<br />
for reduced friction.<br />

CAMSAVER <strong>HYDRAULIC</strong> LIFTERS<br />
The maximum in cam lobe and lifter life.<br />
If high spring pressures or extreme and<br />
unusual operating conditions have you<br />
worried about lobe scuff and lifter wear,<br />
insist on <strong>Crower</strong> “high-lube” CamSaver<br />
lifters. These lifters deliver 20% to 30%<br />
more oil to your lobe and lifter faces<br />
for the best possible insurance against<br />
premature lobe and lifter failure. Specially<br />
machined flats put 12 to 16 ounces<br />
of additional oil per minute at each lobe<br />
without adversely affecting engine oil<br />
pressure (nominal drop of just 1 or 2<br />
pounds). <strong>Crower</strong> CamSaver lifters incorporate<br />
the same precision ground radius<br />
face and finish as our standard lifters to<br />
insure quick break-in and trouble<br />
free operation.<br />

CROWER EDM OILING<br />
Electronic Discharge<br />
Machine allows <strong>Crower</strong><br />
engineers to place precision<br />
holes without the use of a<br />
drill bit. Delivers more oil to<br />
critical, high load areas.<br />
With today’s high rpm, high rocker ratio<br />
and high spring pressures, cam and lifter<br />
failure is at an all time high. <strong>Crower</strong>’s all new<br />
“CoolFace” lifter option is a must for these<br />
applications. Features a small diameter<br />
oil metering port (.024") that is precision<br />
machined in the face of the lifter. No<br />
significant oil pressure loss, but significantly<br />
improved cam and lifter longevity.<br />
<strong>Crower</strong> has a complete inventory<br />
of .842", .874", and .903" diameter lifters<br />
to choose from, including piddle valve,<br />
edge orifice, small chamfer, no chamfer and<br />
lightweight designs. Call <strong>Crower</strong> for pricing<br />
and availability. <strong>Crower</strong> also offers the<br />
“CoolFace” option on competitor’s solid lifters<br />
as well. Send your competing brand lifters in<br />
to <strong>Crower</strong> for precision EDM machining.<br />

Lifters – Roller<br />
Precision ground oil metering<br />
holes deliver plenty of oil flow<br />
to the overhead, vital for longer<br />
pushrod and valve spring life.<br />
Captive blades are secured<br />
with <strong>Crower</strong>’s exclusive<br />
orbit formed locking<br />
mechanism for permanent<br />
spool attachment.<br />
<strong>Crower</strong>’s “beefy” blades<br />
are made from premium<br />
steel alloy to insure<br />
the absolute strongest<br />
fastening system<br />
available.<br />
<strong>Crower</strong> rollers are<br />
available in all popular<br />
designs (full body and<br />
cutaway) as well offsets,<br />
body diameters.<br />
HIPPO<br />
(High-Pressure Pin Oiler)<br />
Hi-Pressure Pin Oiler allows <strong>Crower</strong> engineers to place a<br />
precision .024" hole directly from the oil band to the needle<br />
bearings. Delivers more oil to critical, high load areas for<br />
greatly improved cycle life. Specify “H” after lifter part<br />
number to order (ex. 66200H-16).<br />
HIPPO oiling features<br />
.024" oil metering<br />
hole that delivers<br />
plenty of lubrication<br />
to the needle<br />
bearings and pin.<br />
Redesigned bearing slot<br />
provides more shrouding<br />
around critical bearing<br />
area reducing tappet and<br />
lifter bore wear.<br />
Utilizes longer, “control<br />
contoured” tapered needle<br />
bearings that deliver<br />
unsurpassed load capacity and<br />
correct for irregular tappet<br />
alignment.<br />
<strong>Crower</strong> roller lifter tappets<br />
feature crowned bearings<br />
and crowned outer race<br />
that greatly reduces lobe<br />
tracking.<br />
Integral one piece body<br />
reduces weight without<br />
compromising strength<br />
and delivers the utmost<br />
in rigidity and axle<br />
trueness.<br />
CNC machined, heattreated<br />
body for best<br />
possible wear resistance.<br />
Unique orbit formed pin<br />

MOST<br />
POPULAR<br />
PUSHROD<br />
ENDS<br />
CROWER PUSHRODS<br />
Only the finest 4130<br />
seamless chromoly tubing<br />
is used to manufacture<br />
<strong>Crower</strong> pushrods. All<br />
ends are heat-treated to a<br />
surface hardness of RC60<br />
for maximum durability<br />
and wear resistance.<br />
<strong>Crower</strong>’s standard pushrod<br />
design features an end-totube<br />
spot weld fastener<br />
for extended use. For<br />
severe duty or guide plate<br />
applications see our vast<br />
assortment of RC60 Series<br />
pushrods.<br />
ADJUSTABLE PUSHRODS<br />
When going from hydraulic<br />
to solid lifters, adjustable<br />
pushrods are often required<br />
if there is no adjustment<br />
provision at the rocker<br />
arm. The overall length of<br />
<strong>Crower</strong> adjustable pushrods<br />
is listed with adjustable<br />
end in the middle of the<br />
adjustment range.<br />
NON-ADJUSTABLE<br />
PUSHROD KITS<br />
Non-adjustable pushrod<br />
kits include the following:<br />
• 16 non-adjustable<br />
pushrods (1⁄4" longer than<br />
stock) with one end out.<br />
• 16 pushrod ends.<br />
• One adjustable pushrod<br />
(two if intake & exhaust are<br />
different lengths).<br />

CUSTOM LENGTH<br />
PUSHRODS<br />
<strong>Crower</strong> is one of the<br />
world’s largest producers<br />
of custom pushrods and<br />
can fabricate a pushrod<br />
set for any engine make.<br />
Specify overall length, tube<br />
diameter, tube strength and<br />
type of ends you require.<br />
Three piece pushrods are<br />
available on a special order<br />
basis.<br />
CORRECT VALVE TRAIN<br />
GEOMETRY<br />
Correct pushrod length is<br />
critical in achieving proper<br />
valve train geometry.<br />
When measuring pushrod<br />
lengths, be sure to consider<br />
any head or block milling.<br />
We recommend using<br />
a checking pushrod<br />
for the most accurate<br />
measurement (refer to<br />
pushrod accessories<br />
located later in this section).<br />
ORDERING<br />
When ordering <strong>Crower</strong><br />
pushrods, please include<br />
the part number, cubic<br />
inch, model, make and year<br />
of engine, type of rocker<br />
arm and lifter used, as well<br />
as the overall pushrod<br />
length, tube diameter, tube<br />
strength and type of ends<br />
desired. This information<br />
is critical in order to<br />
manufacture the correct<br />
pushrods required.<br />

Rocker Arms<br />
Back in 1957, <strong>Crower</strong><br />
pioneered the very first<br />
shaft rocker arm assembly<br />
mounted on a stock small<br />
block Chevy cast iron<br />
cylinder head. The race was<br />
the Indy 500 and <strong>Crower</strong><br />
has been making high quality rocker arms ever since.<br />
The weak link in any pushrod engine is the rocker arm<br />
and rocker arm flex. Eliminating flex is an important<br />
factor toward developing maximum horsepower. <strong>Crower</strong><br />
has made significant improvements toward perfecting<br />
shaft rockers for use in high performance engines.<br />
Over the decades of working with you, the racers and<br />
engine builders, we’ve learned to study the problems<br />
you encounter. We’ve made note of your wish lists.<br />
We’ve scrutinized failed components...done our home<br />
work! Consequently, we’ve been able to offer solid,<br />
viable, cost effective solutions that do not compromise<br />
strength. You’ll find that all our stud and shaft mount<br />
rocker arm systems achieve the critical balance of<br />
weight considerations without compromising<br />
enduring strength. <strong>Crower</strong> valve train components<br />
are characteristically strong, able to maintain<br />
dimensional integrity under load and at high<br />
rpm so valve actuation is extremely accurate.<br />
Our rocker systems are well thought-out with<br />
regard to proper geometry, minimizing friction<br />
and heat build-up so the parts live and rpm<br />
freely. The shaft setups are user friendly so<br />
they are easy to work on at the track and<br />
provide accurate, repeatable valve adjustment.<br />
<strong>Crower</strong> rocker systems (stud or shaft mount)<br />
are available for most popular cylinder heads,<br />
often in your choice of material, stainless steel<br />
or aluminum. <strong>Crower</strong> Cams & Equipment Company...<br />
aero space materials, state-of-the-art production<br />
facilities and savvy engineers solving problems with<br />
creativity, technology and common sense. The<br />
result? The finest valve train componentry you can<br />
equip yourself with! You’ll find no better rocker<br />
systems available at any price!<br />

The lighter tip delivers greater valve<br />
control for increased rpm and improves valve<br />
spring longevity by decreasing heat over<br />
traditional non needle designs.<br />
Our Axles are “super secured” for<br />
trouble free operation.<br />
Fully rollerized precision<br />
needle bearing fulcrum.<br />
<strong>Crower</strong> shafts are CNC<br />
precision machined<br />
from ball race alloy<br />
steels, heat-treated<br />

ground in-house.<br />
Ideal rocker<br />
geometry at<br />
half valve lift<br />
Highest unit loading<br />
on the valve train is approximately at<br />
half lift (45° @ cam lobe)<br />
This configuration minimizes<br />
tip travel across the<br />
valve stem and keeps contact<br />
centered on top of the<br />
valve, reducing frictional<br />
losses due to valve guide<br />
side loading and tip scrubbing.<br />
Pushrod deflection<br />
is also minimized for more<br />
accurate valve action.<br />
Rocker Ratio<br />
Rocker arm ratio is<br />
determined by dividing<br />
the distance from<br />
the fulcrum to the tip<br />
centerpoints (Y) by<br />
the distance from the<br />
fulcrum to the pushrod<br />
seat centerpoints (X).<br />
This theoretical ratio<br />
may vary from our net/<br />
advertised ratio due to<br />
measured valve train<br />
deflection under load.<br />
Long Arm<br />
Higher rocker ratios<br />
require extending the<br />
arm of the rocker. Long<br />
arm rockers allow proper<br />
pushrod seat positioning<br />
in relation to the fulcrum<br />
point. An additional long<br />
arm benefit is reduced<br />
back and forth tip travel<br />
across the valve stem. Less<br />
scrubbing and valve stem<br />
side loading occur and<br />
associated frictional losses<br />
are minimized.<br />
Tip Travel<br />
No Lift<br />
contact slightly behind centerline<br />
When the valve is closed tip<br />
contact is slightly behind the<br />
centerline of the valve.<br />
Half Lift<br />
centerline contact 1/2 lift<br />
At highest unit loading (approx. 1/2 lift) tip contact ideally is<br />
on the centerline of the valve. The valve train is overcoming<br />
spring pressure and, more importantly, rapidly accelerating<br />
its mass. To minimize deflection, side loading and frictional<br />
loss, we want the valve train geometry in its strongest and<br />
straightest configuration at this point.<br />
Full Lift<br />
contact slightly behind centerline<br />
When the valve is open, tip contact is slightly behind<br />
the centerline of the valve. The valve train in this<br />
position (at high RPM) feels the least amount of<br />
unit loading as float approaches...everything gets<br />
momentarily weightless.<br />

Determining Which <strong>Crower</strong> Shaft<br />
Rocker System Fits Your Needs<br />
If you’re not sure or don’t know which <strong>Crower</strong><br />
Shaft Rocker System will fit your cylinder head, or<br />
the type/model of head you have and need help,<br />
follow these simple procedures:<br />
1. You’ll need to provide us with some critical<br />
information and dimensions.<br />
a. Cylinder head manufacturer<br />
b. Engine type<br />
c. Intake and exhaust valve distances from<br />
cylinder head centerline.<br />
d. Rocker stud spacing from cylinder head<br />
centerline.<br />
Here’s how you do it.<br />
Measure the distance between the centerlines<br />
of the two inboard exhaust valves and record the<br />
value. If you divide this measurement in two you’ll<br />
know the distance each valve is from the cylinder<br />
head centerline.<br />
Now measure the distance between the<br />
centerline of the exhaust valve and the centerline<br />
of the intake valve.<br />

to provide your <strong>Crower</strong> technician with the following info.<br />
Rocker Bodies without I.D. numbers:<br />
• Rocker arm Ratio<br />
• Rocker arm Offset<br />
• Which valve the rocker actuates<br />
(intake or exhaust)<br />
• Which cylinder the rocker is<br />

Break-In Aluminum<br />
Rollerized Rockers<br />
Reduce cam and lifter break-in failures by running <strong>Crower</strong>’s new<br />
break-in rocker arms first. Features a reverse offset trunnion<br />
(.050") that repositions the pushrod closer to the stock position. In<br />
other words, <strong>Crower</strong> moves the rocker arm and pushrod forward<br />
.050" for easier installation. Current break-in rockers on the<br />
market only offer center trunnion stud hole positions that require<br />
extensive cylinder head modifications to the pushrod hole in order<br />
to achieve proper pushrod and head clearance. <strong>Crower</strong>’s break-in<br />
rockers drop on with no machine work required. Spring pockets<br />
machined for 1.560" O.D. spring<br />

All <strong>Crower</strong> stud and shaft mount rocker arms are available with<br />
<strong>Crower</strong>’s new needle bearing roller tip option. Results are greatly<br />
reduced friction for added horsepower and reduced valve<br />
guide and valve stem wear. The lighter tip delivers greater<br />
valve control for increased rpm and improves valve<br />
spring longevity by decreasing heat over<br />
traditional non needle designs. Specify<br />
#73715R option for stainless<br />
steel (stud or shaft)<br />

Shaft-Mounted Rocker Arms<br />
Stainless Steel<br />
For those of you that feel most confident running<br />
a steel based valve train, we offer you the<br />
<strong>Crower</strong> collection of shaft mounted stainless<br />
steel rocker arms. Each and every configuration<br />
has been religiously scrutinized to offer<br />
extreme rigidity and accuracy while optimizing<br />
moment of inertia phenomena condition.<br />
<strong>Crower</strong> engineers made ease of installation<br />
and maintenance a top priority so you’ll never<br />
waste a moment when time is critical at the<br />
track. Our stainless steel shaft rocker systems<br />
are a perennial favorite of dirt late models and<br />
marine endurance competitors. Sustained high<br />
temperature has little affect on the strength<br />
properties of stainless steel so components<br />
made from this material should have a longer<br />
life expectancy than similar components made<br />
from aluminum.<br />

Shaft-Mounted Rocker Arms<br />
Each of our Aluminum Shaft Rocker<br />
configurations is impeccably designed<br />
and produced to maximize valve train<br />
rigidity and accuracy while offering a<br />
minimal amount of reciprocating mass.<br />
We have utilized the longest arm<br />
lengths practical for each application.<br />
The results are minimal rocker tip<br />
travel and associated frictional<br />
losses as well as the capability to<br />
accommodate large diameter valve<br />
springs with ease.<br />
Speaking of ease, these set-ups<br />
allow for the quickest at-the-track<br />
valve train modifications around. Any<br />
task that requires rocker removal can<br />
be performed without concern for<br />
absolute accuracy and repeatability<br />
upon reassembly.<br />

LASH CAPS<br />
<strong>Crower</strong> lash caps protect the ends<br />
of your valves from excessive wear<br />
and help to correct rocker geometry<br />
by increasing rocker arm to retainer<br />
clearance. Machined from high<br />
grade chromoly steel and heattreated<br />
for added strength, <strong>Crower</strong><br />
lash caps give your valves an added<br />
.060" margin of protection. Highly<br />
recommended for performance<br />
applications, and a must for costly<br />
stainless steel or titanium valves.<br />
Also available in singles by replacing -16 with -1.<br />
BILLET PERFORMANCE 7°<br />
VALVE STEM KEEPERS<br />
<strong>Crower</strong> billet performance valve stem<br />
keepers are precision machined from<br />
premium billet bar stock chromoly<br />
steel. Heat-treated for maximum<br />
strength to insure against shoulder<br />
shearing (common with stock and<br />
lesser quality keepers). In addition<br />
to our standard height, we also<br />
offer .050" higher and .050" lower to<br />
achieve the correct installed spring<br />
height. Each variation is color coded<br />
for identification. Serious engine<br />
builders should have a complete<br />
selection on hand at all times.<br />

Connecting Rods<br />
THE CROWEROD DIFFERENCE<br />
An extensive effort in CAD (Computer Assisted Design) & F.E.A (Finite Element<br />
Analysis), as well as rigorous dyno and track testing have been expended<br />
through perfection of our strongest yet lightest rods available. When you<br />
employ a set of genuine <strong>Crower</strong>ods you do so with the knowledge and<br />
peace of mind that each rod will perform flawlessly. That’s why they are<br />
hands down, the favorite of professional and amateur engine builders<br />
throughout the world.<br />
IT’S THE MATERIAL...<br />
While other manufacturers are<br />
cutting corners, using inferior<br />
or low grade materials, <strong>Crower</strong><br />
has kept costs down without<br />
lowering our standards.<br />
<strong>Crower</strong>ods incorporate only<br />
the finest aircraft quality steel<br />
and titanium materials. They are<br />
heat treated to obtain that perfect<br />
balance of strength and durability ,<br />
to insure the best quality and<br />
reliability possible.<br />
AND THE DESIGN<br />
Take a close look at a <strong>Crower</strong>od and you’ll notice that it is shaped like no other<br />
rod in the industry. Every contour is designed to enhance overall strength and<br />
reliability at high engine rpm. <strong>Crower</strong> connecting rods incorporate an “I-beam”<br />
design that eliminates pockets of excess material and delivers exceptional<br />
longitudinal and horizontal strength. The cap screw design assures true<br />
roundness and a positive bearing seat under severe load factors, in which<br />
eliminating rod bearing failure. Tolerances are to an exacting ±0.0001" of an<br />
inch to insure trouble free installation. For those who prefer an “H-beam”<br />
design, <strong>Crower</strong> also offers this style of rod on a custom order basis.<br />
CROWER, your # 1 source for rods.<br />
CROWER makes rods for<br />
almost any application.<br />
THE BOTTOM LINE<br />
When you install a set of genuine <strong>Crower</strong>ods in your high performance engine, the design expertise, material and<br />
craftsmanship are working hard to maximize your racing effort. It’s the kind of dependability and confidence that<br />
can put you in the winner’s circle. <strong>Crower</strong>ods are available for most domestic and foreign applications, as well as<br />
motorcycles, industrial, vintage and one of a kind prototypes. Our <strong>Crower</strong>od design is often imitated, but never<br />
duplicated. For any new enthusiast we have an excellent staff that can help you on any particular design you may<br />
want. Protect your investment by insisting on only genuine <strong>Crower</strong>ods for your high performance needs.<br />

“RBT” Steel Billet Connecting Rods<br />
Aircraft quality, 12-point cap<br />
screw fastening system provides<br />
added security at high rpm.<br />
<strong>Crower</strong>’s all new Radial Beam Technology design ( “RBT” ) is the<br />
ultimate connecting rod, often copied by competitors, but never<br />
replicated to <strong>Crower</strong>'s engineered standards. The radial shape<br />
beam delivers unsurpassed beam support while reducing overall<br />
weight for greater throttle response...quicker deceleration into<br />
the corner and faster acceleration off the corner.<br />
Drilled and chamfered pin oil<br />
hole on all <strong>Crower</strong>ods provides<br />
additional oil at the pin end to<br />
prevent galling. The high alloy,<br />
aluminum-bronze, one piece<br />
bushing delivers long, reliable<br />
service.<br />
H11 - Tool Steel bolts rated to<br />
220,000 p.s.i. come standard.<br />
For extreme duty, <strong>Crower</strong> highly<br />
recommends the AMS5844 rod<br />
bolt upgrade rated to 280,000 p.s.i.<br />
for ultimate clamping ability.<br />
Extra strength at the critical web area<br />
reduces the big end pinch found<br />
in other inferior designs. Big end<br />
roundness is paramount for long<br />
bearing and connecting service.<br />
Pin boss dynamics are essential<br />
when designing a high<br />
performance connecting rod. To<br />
maintain trouble free operation,<br />
<strong>Crower</strong> beefs up the pin eye area.<br />
The <strong>Crower</strong> Maxi-Light is a<br />
proven performer on the race<br />
track. Tapered beam design<br />
delivers the strength you need in<br />
a lightweight, yet reliable profile.<br />
Hollow dowel alignment<br />
fastening system provides<br />
positive cap alignment and<br />
prevents unwanted cap walk.<br />
RADIAL BEAM TECHNOLOGY (“RBT”)<br />
MAXI-LIGHT DESIGN<br />
<strong>Crower</strong>’s exclusive “RBT” Maxi-Light design is a<br />
revolutionary new beam shape that removes excess<br />
material from noncritical stress areas for the lightest,<br />
yet strongest connecting rod available on the market.<br />
Choose from a wide variety of weight configurations,<br />
depending on your individual horsepower and rpm<br />
requirements.<br />
AMS5844 ROD BOLT UPGRADE<br />
<strong>Crower</strong>’s AMS5844 rod bolt upgrade is available<br />
for all steel billet and titanium rods. Highly<br />
recommended for extreme duty rpm<br />
and endurance applications. Rated at<br />
280,000 p.s.i., these bolts are corrosion<br />
resistant, nonmagnetic and deliver<br />
ultimate clamping capabilities for the<br />
highest cycle life. Specify desired rod bolt<br />
part number when ordering.<br />
Proper bolt torque: Torque rod bolts to 10 ft lbs on both sides,<br />
then torque to proper spec with one pull.<br />
Upgrades: 280,000 p.s.i. rod bolts, specify #90842 for 3⁄8<br />
280,000 p.s.i. rod bolts, specify #90830 for 7⁄16<br />

Steel Billet Connecting Rods<br />
STEEL BILLET ROD WITH 12 POINT CAP SCREW BOLT<br />
Unquestionably the most critical part of a high performance, internal combustion<br />
engine is the connecting rod. Connecting rods support the primary tension loads<br />
caused by engine operation in each revolution or cycle of the crankshaft. Therefore,<br />
it is of utmost importance that the rods you choose to put in your engine are made<br />
from only the finest quality materials, manufacturing methods and fastening systems<br />
available on the market. For over 30 years, <strong>Crower</strong> has been<br />
meeting this challenge by using the finest quality steel in<br />
the production of our steel billet connecting rods. Every rod<br />
is fully CNC machined to remove all surface imperfections,<br />
100% magnaflux inspected, checked for hardness and then<br />
machined to finalize the exact tolerance within 0.0001" of an<br />
inch. Each set of rods is fully balanced and then shot peened<br />
to achieve the ultimate in strength and reliability. Choose<br />
from premium H-11 tool steel rod bolts or available as an<br />
upgrade, AMS5844 bolts.<br />
An assortment of computer<br />
designed beams are available<br />
for different horsepower and<br />
weight requirements.<br />
<strong>Crower</strong>’s RBT beam features<br />
a radius beam design for<br />
the utmost in strength<br />
capabilities while reducing<br />
overall weight of the rod for<br />
improved throttle response.<br />
Drilled and chamfered<br />
pin oil hole on<br />
<strong>Crower</strong>ods provides<br />
additional oil at pin<br />
end to prevent<br />
galling. Available in<br />
aluminum/ bronze<br />
bushed or pressed<br />
fit pin.<br />
Pin boss dynamics<br />
are critical when<br />
designing a high<br />
performance<br />
connecting rod. To<br />
maintain troublefree<br />
operation,<br />
<strong>Crower</strong> beefs up the<br />
pin eye area.<br />
CROWER H-BEAM DESIGN<br />
Hollow dowel alignment<br />
fastening system provides<br />
positive cap alignment and<br />
“no hassle” removal.<br />
Integrally threaded beam<br />
can be made to accept<br />
bolt diameters of 5⁄16, 3⁄8<br />
and 7⁄16.<br />
Deep, double-ribbed<br />
cap guarantees<br />
superior strength<br />
and reliability at high<br />
engine rpm.<br />
Only <strong>Crower</strong> offers you, the engine builder,<br />
the choice of “I-Beam or H-Beam” design.<br />
AMS5844 ROD BOLT UPGRADE<br />
<strong>Crower</strong>’s AMS5844 rod bolt upgrade is<br />
available for all steel billet and titanium<br />
rods. Highly recommended for extreme<br />
duty rpm and endurance applications.<br />
Rated at 280,000 p.s.i., these bolts are<br />
corrosion resistant, nonmagnetic and<br />
deliver ultimate clamping capabilities<br />
for the highest cycle life. Specify desired<br />
rod bolt when ordering.<br />
Proper bolt torque: Torque rod<br />
bolts to 10 ft lbs on both sides, then<br />
torque to proper spec with one pull.<br />
Extremely reliable H-11<br />
tool steel bolts, rated at<br />
220,000 p.s.i. or aircraft<br />
quality, AMS5844 alloy<br />
bolts that are corrosion<br />
resistant and rated at<br />
280,000 p.s.i. Both feature<br />
12-point heads.<br />
MAXI-LIGHT DESIGN<br />
CROWER “H-BEAM” CONNECTING RODS<br />
Although <strong>Crower</strong> is known mostly for it’s “I-Beam” rods, we also build a variety<br />
of European influenced “H-Beam” designs as well. The thicker cross sections<br />
of the H-Beam are better suited for the EDM oil hole that runs the length of<br />
the beam delivering added oil to the pin. Weights are equivalent to <strong>Crower</strong>’s<br />
standard “I-Beam” billet rod. Specify H-Beam when ordering. For Pressure Fed<br />
Pin option specify #90798 after rod part number.<br />

Titanium Connecting Rods<br />
TITANIUM RODS<br />
<strong>Crower</strong> uses only aerospace quality,<br />
titanium in the manufacturing<br />
of our billet <strong>Crower</strong>ods. Titanium<br />
has a lower thermal expansion<br />
rate than steel and much less than<br />
aluminum, which allows the racer<br />
to hold closer tolerances within the<br />
engine. <strong>Crower</strong> offers a wide variety<br />
of applications. Everything from a<br />
4 cycle motorcycle to a 8" long big<br />
block Chevrolet for Pro Modified. All<br />
<strong>Crower</strong> titanium connecting rods<br />
are equipped with cap screw<br />
bolts and stroker designed to<br />
insure plenty of camshaft<br />
and case clearance, also<br />
reducing weight in<br />
noncritical areas.<br />
Special “pressure fed” oiling hole from big<br />
end to pin end is available on all titanium<br />
and premium steel billet <strong>Crower</strong>ods.<br />
Specify this option when ordering.<br />
All titanium rods come<br />
standard with aluminum/<br />
bronze bushings.<br />
<strong>Crower</strong> uses only titanium,<br />
with a composition of 6%<br />
aluminum and 4% vanadium.<br />
Custom rods available in<br />
most center to center pin<br />
end size and big end I.D.<br />
<strong>Crower</strong> is a complete<br />
production facility.<br />
Every step of manufacture<br />
is performed under rigid<br />
quality control standards<br />
Hollow dowel alignment fastening<br />
system provides positive cap<br />
alignment and “no hassle” removal.<br />
Special plasma sprayed sides<br />
prevents galling that occurs<br />
when titanium rubs with steel.<br />
Extremely reliable H-11 tool steel<br />
bolts, rated at 220,000 p.s.i. or<br />
aircraft quality, AMS5844 alloy<br />
bolts that are corrosion resistant<br />
and rated at 285,000 p.s.i. Both<br />
feature 12-point heads.<br />
AMS5844 ROD BOLT UPGRADE<br />
<strong>Crower</strong> now offers a new AMS5844 rod<br />
bolt upgrade option available for all<br />
steel billet and titanium rods. Highly<br />
recommended for extreme duty<br />
rpm and endurance applications.<br />
Rated at 280,000 p.s.i., these bolts<br />
are corrosion resistant, nonmagnetic<br />
and deliver ultimate clamping capabilities<br />
for the highest cycle life. Be sure and specify<br />
upgrade option when ordering.<br />

Crankshafts<br />
A TYPICAL SCENARIO<br />
For years you’ve been running a stock crank and have<br />
never experienced rod bearing failure. You decide to<br />
“step-up” and replace your stock crank with an aftermarket<br />
brand. Immediately you encounter bearing scuff or total<br />
bearing failure. This scenario happens often, much to the<br />
dismay of the engine builder.<br />
Looking from the rod, back up through<br />
the main, you can see daylight, indicating<br />
it’s a genuine <strong>Crower</strong> crankshaft with the<br />
“straight-shot” oiling system.<br />
The unique teardrop scoop and exclusive<br />
<strong>Crower</strong> “straight-shot” oiling system<br />
increases critical oil flow from the main<br />
bearings to the rod bearings.<br />
Entry holes for the rod feed are located at<br />
the O.D. of the main, allowing oil to flow<br />
equally and unrestricted to the bearings.<br />
This is key to prolonging bearing life.<br />
THE PROBLEM<br />
On most aftermarket<br />
brands the rod feed<br />
hole is only drilled to<br />
the centerline of the<br />
main. This method<br />
of drilling doesn’t<br />
deliver enough oil<br />
to the rod . Creating<br />
a high centrifuge,<br />
high pressure<br />
zone at the main,<br />
restricting critical<br />
oil flow intended for<br />
your rods. As engine<br />
rpm increases this<br />
centrifuge effect<br />
gets worse, possibly<br />
resulting in severe<br />
crankshaft damage<br />
or even total engine<br />
destruction. Not<br />
the performance<br />
characteristics you<br />
expected when<br />
you switched to an<br />
aftermarket brand<br />
crankshaft.<br />
THE SOLUTION<br />
STRAIGHT-SHOT OILING<br />
After extensive<br />
research and design,<br />
<strong>Crower</strong> engineers developed the straight-shot oiling system<br />
and virtually eliminates bearing burnout and customer<br />
complaints. It features two <strong>Crower</strong> exclusives, off-center<br />
drilling and the teardrop design oil hole, which scoops oil at<br />
the main and forces it into the rod feed hole. Although it’s<br />
time consuming, we feel it’s worth it.<br />
THE PROVEN FACTS<br />
It has been proven time and time again, “the lighter the<br />
parts, the quicker the throttle response.” This is no more<br />
evident than in the components that make up the bottom<br />
end of an engine. Reducing a crankshafts counterweight<br />
mass is critical in getting quicker acceleration and<br />
deceleration. It also alleviates stress and engine wear and<br />
improves oil shearing in the pan.<br />
PENDULUM UNDERCUTTING AND<br />
LIGHTWEIGHT PIN WEB AREA<br />
Smaller O.D. design places heaviest<br />
mass closer to the center of the<br />
crankshaft for the quickest engine<br />
acceleration possible.<br />
<strong>Crower</strong>’s “counterweight<br />
correct” design produces<br />
optimum counterweight<br />
positioning for the best<br />
possible bearing loading<br />
and proper balancing.<br />
The shorter,<br />
narrower<br />
counterweight<br />
reduces total<br />
overall mass and<br />
has less frontal<br />
area.<br />
<strong>Crower</strong>’s exclusive lightweight<br />
crank pin web area allows<br />
the counterweights to be<br />
pendulum undercut to reduce<br />
weight without the need for<br />
heavy metal balancing on most<br />
applications.<br />
44.3% less frontal area<br />
improves windage and<br />
oil shearing in the pan,<br />
two external forces<br />
that frequently disrupt<br />
a crankshaft’s uniform<br />
motion.<br />
The “Klose’s Stress<br />
Concentration<br />
Reduction” distributes<br />
stress evenly over the<br />
entire overlap area.<br />
CROWER’S<br />
“Maxi-Light”<br />
REVOLUTIONARY DESIGN<br />
The <strong>Crower</strong> Maxi-Light crankshaft redefines the term “light<br />
rotating mass” by attaining just the right ratio of a smaller<br />
O.D. counterweight with an exclusive lightweight crank<br />
pin web area. By lightening the crank pin web area we are<br />
able to machine excess material from the center of the<br />
counterweights without adversely effecting balancing. This<br />
is <strong>Crower</strong>’s patented pendulum undercutting. Lighter than<br />
any other crankshaft like it on the market, the Maxi-Light<br />
is structurally just as strong and easy to balance. Although<br />
competing manufacturer’s claim to have comparable<br />
designs similar to the <strong>Crower</strong> Maxi-Light, consider the fact<br />
that it takes much more than just scalloping out the center<br />
of the counterweight to achieve the correct combination of<br />
light rotating mass and proper balance. <strong>Crower</strong> pioneered<br />
pendulum undercutting the counterweights back in 1989.<br />

Rod & Main Bearings<br />
ROD BEARINGS<br />
<strong>Crower</strong> high performance rod bearings are<br />
quality engine bearings designed to withstand<br />
the extreme loads of professionally tuned<br />
racing engines. Features high strength trimetal<br />
copper-lead material in the load area for superior<br />
strength and embedding. Lead overplate<br />
provides excellent fatigue strength and superior<br />
conformability to compensate for distortion and/<br />
or misalignment. Superlative bearing-to-bearing<br />
size consistency enables you to “build-in” the<br />
exact oil clearance you require, while narrowed<br />
and chamfered versions are available for large<br />
fillet journals where additional clearance is<br />
necessary. If running aluminum rods, <strong>Crower</strong> has<br />
chamfered rod bearings with dowel pin holes.<br />
MAIN BEARINGS<br />
<strong>Crower</strong> high performance main bearings offer<br />
professional racers and engine builders the<br />
extreme accuracy and bearing-to-bearing<br />
consistency required to build an engine that<br />
can handle the extreme loads associated with<br />
high performance racing. Features high strength<br />
copper-lead in the load area for superior strength<br />
and embedding. <strong>Crower</strong> high performance<br />
main bearings are designed to deliver improved<br />
bearing-to-bore contact for better heat transfer<br />
and a reduction in high rpm bearing chatter and<br />
or failure. Order chamfered bearings, for use with<br />
large fillet journals. A must when running any<br />
<strong>Crower</strong> crank.<br />
