History 

It started as a one-man, part-time operation 

making engine parts for himself and his hot rod buddies 

over 50 years ago. Today it has evolved into a multimillion 

dollar, multifaceted manufacturing operation, producing 

high performance engine equipment for a wide variety 

of applications, including cars, trucks, boats, tractors, 

motorcycles and antiques. 

Crower Cams and Equipment Company, Inc., is a 

leading producer of aftermarket camshafts and valve train 

components. But over the years Crower has developed a 

more diverse line of products. Today, Crower is the world’s 

largest manufacturer of aftermarket crankshafts and 

connecting rods, and the Crower line of clutches has been 

dominating the drag racing and tractor pulling series for 

nearly four decades. 

A young Bruce Crower, left, in his first shop in 1949 near Phoenix, Arizona. 

EARLY THOUGHTS 

Bruce Crower, president of Crower Cams, is the 

thinking man’s racer, saying, “People don’t think as much 

as they should. If you think hard enough, the answer will 

come.” Born in 1930 to a church going family in Phoenix, 

Arizona, he has been thinking about, and implementing 

ways to improve the internal combustion engine for nearly 

six decades. 

INTRODUCTION TO FAST MACHINES 

In 1949, a fast, 80 cubic inch Harley led to a 120 mph, 

300 cubic inch Merc-powered Deuce roadster that Bruce 

says was, “the first Arizona car to beat the bikes,” and his 

own successful speed shop near Phoenix, Arizona. Uncle 

Sam, however, had other plans and he was drafted for the 

Korean war. 

After 18 months on a ground crew in the Air National 

Guard, developing his mechanical skills in a machine shop 

at Luke Field Air Force Base, he followed his parents to 

San Diego and landed a job as a machinist at Paul Schiefer 

Clutches. All over California, especially at Paradise Mesa, 

people were burning up the quarter mile. 

THE CHRYSLER HEMI 

And despite the legendary Bean Bandits’ quantum 

leap from 120 to 140 mph with a Bruce Crower built 

engine, the flathead’s reign was over the day Chrysler 

introduced its OHV Hemi. Bruce was quick to realize the 

Hemi’s potential, and by 1954 he was shakin’ em up on the 

Bonneville salt flats with a 157 mph record breaking run 

behind the wheel of his Hemi-powered Hudson. Credited 

with being the first to top-mount a GMC blower, Bruce had 

fashioned his own intake manifold and a pulley system 

cast in coffee cans using old pistons as material. 

THE “U-FAB” INTAKE MANIFOLD 

The intake/blower combo was a success, and not 

only put Bruce in the record books but also in the manifold 

business. There followed the phenomenally successful 

Crower “U-Fab” do-it-yourself manifold. Consisting of two 

cylindrical runners joined with hoses and clamps, the 

“U-Fab” was designed to hold four, six or eight Stromberg 

carburetors.It was simple, inexpensive and extremely 

popular. “We sold thousands of them,” according to Bruce. 

The mega-popular “U-Fab” 

intake manifold. 

During high school, Bruce found that other hot 

rodders would buy parts that he made for his own ’32 Ford 

roadster. As new ideas came to mind, instead of making 

just one part for himself, he would make several at a time 

and sell them to his fellow hot rodders. It was simple 

arithmetic to see the profit of making thousands of such 

parts and selling them nationwide. 

1955 - THE BEGINNING OF CROWER EQUIPMENT CO. 

With $312 in the bank Bruce booked a sixth 

page ad in Hot Rod for $300. That one ad generated over 

$10,000 dollars worth of orders, and suddenly I was, 

“controlling my own destiny with my own two hands, and 

the harder I worked, the more money I made.” He worked 

until the wee hours of the morning assembling those kits, 

and finally hired his brother, Dave and eventual brother 

in-law, Loren in order to keep the production up with the 

demand. Thus the formation of Crower. 

Bruce ran 157 mph in this Hemi-powered Hudson. 


 


THE “GLIDE” 

Other speed merchants eventually followed his 

lead, tapping into Crower’s market share. But Bruce and 

the boys had been thinking ahead, this time about a double 

disc clutch first seen in a Fiat. Crower combined this 

technology with a Schiefer clutch and applied it towards 

drag racing and, once again, enjoyed another overnight 

success with the “Crowerglide” centrifugal clutch. It quickly 

became the most popular clutch in drag racing. 

CAMSHAFT TECH- 

NOLOGY 

Crower, however, 

was already moving 

on, this time in the 

direction of cam 

technology where 

once again they An early model “CrowerGlide” centrifugal clutch. 

took advantage of 

an industry in low gear. The industry’s shortcomings have 

always provided the impetus for Crower’s ideas. Only the 

experiences at the Indianapolis 500 Brickyard have caused 

him to reevaluate his direction. 

Bruce built this outside port 

design V8 Chevy to improve 

breathing efficiency. 

History 

STATE-OF-THE-ART 

MANUFACTURING 

Today, Crower Cams 

and Equipment 

Company is still 

family owned and 

operated, employing 

over 200 people in our 

new 110,000 sq ft building. 

Utilizing the latest in computer 

assisted design (CAD), 

Crower engineers render multidimensional 

blueprints that are then 

downloaded into one of Crower’s state-of-the-art CNC 

machining centers. This allows more flexibility, with tighter 

tolerances, and gives the customer more choices. Crower 

offers over 10 different styles of steel billet connecting rods 

and five different crank designs for the small block Chevrolet 

depending on the customer’s particular application, 

rpm range and budget. 

THE INDY EXPERIENCE 

In 1954, Bruce Crower was invited to 

work on the Offy-powered Dean Van Lines 

Indianapolis racing car with Jimmy Bryan. They 

qualified on the front row and finished second. 

Six years later, working on Jim Rathmann’s 

team, all of their hard work paid off as they 

went on to win the 1960 Indy 500. He went 

on to win again as a member of Graham Hill’s 

team, and again in 1967 as part of the A.J. Foyt 

team. 

Subsequent years saw Crower cars 

equipped with engines as diverse as a downsized 

small-block Chevy and a custom designed flat-eight 

with Cosworth heads, which received the 1977 SAE “Louis 

Schwitzer Award” for race car design. But over the years, in 

order to remain competitive, teams started preparing year 

around for the race, and Bruce decided that his time and 

money would be better 

spent investing in 

his own business in 

the area of high 

performance 

engine parts 

and engine 

research. 

Bruce, third from right, was on Jim Rathmann’s 

1960 Indy winning crew with Smokey Yunick. 

This downsized 209 

c.i.d. stock block 

Chevy produced over 

850hp at Indy. 

Crower’s new, state-of-the-art of the art building 

features 110,000 sq ft and over 100 CNC machining 

centers. The goal will be to dramatically reduce 

leadtimes on all Crower products. 



History 

RESEARCH & DEVELOPMENT 

Although Bruce Crower is 

no longer involved in the day-to-day 

manufacturing operation, he spends his time 

designing and developing new products at the 

company’s research and development facility 

located at his Jamul ranch. This R&D facility houses 

a complete machine shop and a fully operational, 

computer controlled Heenan-Froude engine 

dynamometer, capable of generating high levels 

of horsepower and torque on just about any type 

of engine. Before Crower introduces a new product 

to the market, you can be sure it has undergone a 

rigorous cycle of testing under dyno simulated racing 

conditions. Each 

Crower product 

is then evaluated 

for maximum 

horsepower and 

torque figures, 

as well as rpm 

specifications to 

insure product 

reliability. 

This 700hp straight-8 Nash was put in 

a Model-T roadster. 

THE BONNEVILLE SALT FLATS 

In addition to product testing and development, both 

of Crower’s Bonneville race cars were completely 

designed and constructed at the Jamul facility. 

A 1927 Model-T roadster equipped with a 700hp 

1931 straight-8 Nash engine, and a state-of-theart 

streamliner powered by a turbocharged small 

block Chevy and a pair of prototype Crower 4-valve 

cylinder heads. He first touted the idea of a four-valve 

production head for the small-block Chevy back in 

1965 after inventing a head with an inlet port on the 

same plane as the exhaust port. Chevy engineers 

were so impressed they had prototypes drawn and 

cast within 30 days. Unfortunately, the various race 

sanctioning bodies indicated that they would have to 

ban it because it would have given certain racers an 

unfair advantage. The streamliner, however, is in the 

Unlimited Class and with the help of the heads and 

some other radical design solutions, it is projected 

to run over 440 mph at 1150 horsepower on the 

Bonneville salt flats. 

The streamliner’s pair of 4-valve cylinder heads were handcrafted by Bruce. 

RECOGNIZING HIS DEDICATION 

In recognition of Crower’s innovative products for 

drag racing, Bruce Crower was inducted into the Drag 

Racing Hall of Fame located in Florida. An honor and 

privilege that is the direct result of his hard work and 

dedication to the industry that he loves so much. 

USING QUALITY, AMERICAN MADE MATERIALS 

The secret to Crower’s lasting success, according to 

Dave Crower, vice president and general manager 

of Crower, is that basically “we make what people 

ask for. We do it with better quality than anyone 

else, plus we do it lighter, which is the key to quicker 

elapsed times.” Not one to compromise the strength 

and integrity of Crower’s products, Crower uses USA 

milled materials in its manufacturing. Although 

cheaper products can be imported from other 

countries, the Crower philosophy has always been 

that “If a product is made right the first time, using 

the highest quality materials and the latest 

production methods, it will perform flawlessly to it’s 

intended ability.” 

Crower’s custom built 

streamliner is powered by a 

turbocharged SB Chevy 

with 4-valve heads.

Camshaft Selection 

VEHICLE PACKAGE 

It is the complete vehicle package that will determine how well your vehicle satisfies your 

performance preference. 

By complete vehicle package we mean the interaction of all a vehicle’s components and 

subsystems, including the engine and its related parts (such as the carburetor, intake manifold, 

exhaust system, camshaft and ignition), the transmission, rear end gears, wheel and tire 

combinations and diameters and suspension pieces. All of these components must work in 

unison to produce the desired performance results. 

RPM POWER RANGE 

Before thumbing through the collection of profiles listed on the following pages you will need 

to formulate a definite idea of your motoring requirements. Doing so will dictate what rpm 

power range you will be operating in most often (see Fig. 1). Because camshaft selection as well 

as carburetion, manifold choice and gearing are based on it, knowing your rpm power range is 

the key to building a successful vehicle package. 

Be realistic when examining your driving style, the vehicle’s present engine/drive train 

components and your pocket book. Be sure you can afford to purchase all of the components 

necessary to complete the desired vehicle package at your performance level. Remember, 

the further from stock you deviate in the engine department, the more modifications will be 

required elsewhere in the vehicle. 

Refer to the five performance levels listed below for an idea of the components required to 

produce a successful vehicle package at the performance level you desire. 

Approximate RPM Power Range: 

Hydraulic camshafts - Idle to 3500 / Redline: 4500. 

Solid camshafts - 1000 to 4000 / Redline: 5000. 

LEVEL 1 CAMS 

MILEAGE & TORQUE 

Level 1 indicates a good stock replacement camshaft. These profiles are designed to enhance 

throttle response and low end torque in vans, trucks, passenger cars and mild marine 

applications while delivering fuel efficient motoring. High vacuum, smooth idle and maximum 

efficiency are characteristics of these cams. Stock or small cfm carburetor, small diameter 

tube headers and dual exhaust are recommended for maximum benefit. Intended for stock or 

near-stock engines and drive trains, 8.5:1 compression, 2.70 to 3.25 ring and pinion, automatic 

transmission with stock converter or four-speed manual transmission. 


Hydraulic camshafts - 1500 to 4000 / Redline: 5500. 


LEVEL 2 CAMS 

MILEAGE & POWER 

Level 2 profiles are for individuals that require more power and an extended rpm range. Works 

well with stock or near-stock engines and drive trains. These camshafts provide excellent low 

end and mid-range power for spirited street and off road driving and mild marine applications. 

Modifications that should accompany installation of these cams include small diameter tube 

headers, low restriction dual exhaust, aftermarket manifold, increased cfm carburetor and 

reworked or performance ignition. Increased compression (9.5:1) is recommended for maximum 

output. Aftermarket torque converter with slightly higher stall speed is recommended because 

stock factory converters do not allow the engine to provide adequate idle speed and off idle 

performance. Works well with four-speed manual transmission. Designed for lightly modified 

street engines. 

 



Camshaft Selection 

LEVEL 3 CAMS 

HIGH 

PERFORMANCE 




Hydraulic roller camshafts - 2000 to 4700 / Redline: 6250. 

Level 3 camshafts are designed for moderately modified engines. Intended for performance hot 

street/strip and performance marine applications, these profiles have a moderate lope at idle and 

offer an extended rpm range with emphasis on upper bottom to top end power and a strong midrange. 

These higher lift, longer duration camshafts demand close attention to rear end gearing and 

tire diameter combinations. The secret here is to pick a ring and pinion gear set and tire diameter 

that keeps the engine in its optimum rpm power range (see Fig. 1). These profiles perform well 

with four-speed manual transmissions or automatic transmissions if a high stall torque converter is 

employed. Headers, dual exhaust, larger than stock carburetor, performance manifold and increased 

compression (9.5:1 to 10.5:1) are required. Mild porting and larger valves will improve performance. 

LEVEL 4 CAMS 

ULTRA 

PERFORMANCE 




Hydraulic roller camshafts - 2200 to 5000 / Redline: 6500. 

Level 4 camshafts are designed for heavily modified engines. They have a definite lope at idle and 

are best suited for dual purpose hot street/drag strip, hot marine and oval track applications. These 

grinds exhibit strong mid-range to top end torque and horsepower. Headers, dual exhaust, large 

cfm carburetor, performance ignition and increased compression of 10.25:1 and above are required. 

Cylinder head modifications would be beneficial. Use with standard manual transmission or 

automatic with high stall torque converter. Again, close attention to proper ring and pinion and tire 

diameter selection is imperative. 

LEVEL 5 CAMS 

COMPETITION/ 

RACE ONLY 

Level 5 camshafts are designed for fully prepared, high compression, all-out racing engines and 

chassis. Extensive cylinder head modification, bigger valves, lightweight valve train, titanium valves, 

maximum flow carburetion or fuel injection, racing gas, alky or nitro, magneto or electronic ignition, 

performance rod and crank assembly and increased engine clearances are required for maximum 

benefit. 

The wide selection of level 5 profiles enable the experienced engine builder to choose the proper 

camshaft for his particular application, whether it be drag racing, oval track competition, tractor 

pulling or performance marine. If you are uncertain as to which cam profile best suits your needs, 

please contact our technical support staff at 619-422-1191.

BE SMART! Crower performance camshafts feature high lift, fast action features that 

can cause stock or other aftermarket valve train components to fail. Be sure to use a 

Crower engineered kit to avoid possible damage. 


CROWER CAM BREAK-IN PROCEDURE 

This applies to all hydraulic and solid lifter camshafts using higher than 

stock spring pressure: 

• Do not use block restrictors in the oil galleys. This severely limits oil flow 

to the cam, lifters and overhead. 

• Break-in cam and lifters with low pressure springs only. Do not exceed 225 

to 250 lbs open pressure. 

• During break-in run engine for 35 to 45 minutes and vary rpm from 

2000 to 3000. 

• For break-in procedure Crower recommends 10W/30 motor oil. Heavier weight oils 

do not cold flow. 

• Do not use synthetic oils during break-in period. 

• For further information, please refer to the Crower Installation booklet that accompanies the camshaft.

Level 1 - These cams are designed to enhance 

throttle response and low-end torque in vans, 

trucks and passenger cars while delivering fuel 

efficient motoring. High vacuum, smooth idle 

and maximum fuel efficiency are characteristic to 

these profiles. Stock or small cfm carburetor, small 

diameter tube headers, dual exhaust, and ignition 

rework are recommended for maximum benefit. 

Intended for low compression engines operating in 

the “economy zone.” 

RPM Power Range: Idle to 3500-3700 / Redline:

POWER COMPU-PRO / Performance Level 2 

- These cams provide excellent low end and midrange 

power and extended rpm range for spirited 

street and off-road driving. A perfect combination 

of mileage and power. Modifications should include 

small diameter tube headers, low restriction 

dual exhaust, aftermarket manifold, increased 

cfm carburetor and reworked or performance 

ignition. Increase in compression ratio to 9.5:1 is 

recommended for maximum output. 

Works well with automatic transmission or 

4-speed.

* These cid engines (383, 406) require a smaller base circle for 3.750" or larger stroke cranks. Add an “S” at the end of 

desired cam part number (example: 00275S) if smaller base circle is desired. 

Note: Small base circle cams are available if using 3.750" stroke and 350 style rods. Specify “S” after part 

number. If using 400 style or stroker rods the above base circle will work.

For rpm up to 6500 max. Race only. 



For rpm up to 6500 max. "Cam Saver" Lifters 

For severe duty applications, Crower offers a high-lube “CamSaver” lifter that channels more 

oil to the cam lobe and lifter surface. Specify X3 after corresponding component kit. 






Note: If using 3.750" stroke or above cranks, contact Crower for smaller base circle camshafts for more 

rod clearance. 

BE SMART! Crower performance camshafts feature high lift, fast action features that can cause stock or other 

aftermarket valve train components to fail. Be sure to use a Crower engineered kit to avoid possible damage. 

CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance at 

full lift (minimum .050"). 

LIFT RULE CAMSHAFTS: Crower has a complete line of camshafts that will satisfy any max lift requirement.

See pg. 180 Spring seat cutter 

Pg.146-149 Pushrods 

Pg's.150-165 Rocker arms (1.5) 3⁄8 


See pg. 136 Timing gear kit 

Note: If using longer than stock valves you 

may require spring and retainer modifications. 

See specs or contact Crower. 

REMEMBER! Increasing rocker ratio on intake 

(1.6) will make the cam approximately 

3° duration and .030" more lift. 

HIGH RPM! Crower highly recommends the 

use of rollerized rockers. See rocker section for 

ratios and stud diameters. 

These camshafts will work with the following 

carburetor sizes: 350 (210 cfm), 390 (410 cfm), 

500 (350 cfm). 

If you can supply cylinder head flow data, 

engine specs, operating power ranges and 

exhaust manifold configurations we will be 

able to grind you a camshaft that is far superior 

than any other brand currently available.

*86781-16 and 86767-16 retainers require Super 7° keepers. Titanium valves required to achieve high rpm. 

Due to the wide variety of valve train combinations (i.e. lifter bore diameters, offsets, valve lengths, installed 

heights, etc...), we highly recommend that you contact Crower for your specific valve train needs. 

HIPPO Note: For severe duty roller lifter applications, we highly recommend using our roller lifters with 

Hippo “High Pressure Pin Oiling”. Specify “H” in the part number. 

Ex. 66290X874H-16 

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. For strokes of 3.900" or larger contact Crower for .850" base 

circle camshafts. 

HIGH RPM! With today’s high engine rpm and increased rocker ratios, valve train life is extremely critical. 

Increased spring pressures are mandatory for insuring reliable valve train life. Contact Crower’s technical assistance 

department for proper high rpm recommendations. 

INTEGRAL CAST IRON GEAR OPTION: Premium 8620 steel billet, copper plated cam cores with integral cast 

iron cam gear are available from Crower on a special order basis (specify part number 00050). Valve timing 

events are available online at: www.crower.com/valvtime.html

Due to the wide variety of valve train combinations (i.e. lifter bore diameters, offsets, valve lengths, installed heights, etc...), we highly recommend 

that you contact Crower for your specific valve train needs. 

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. 

For strokes of 3.900" or larger contact Crower for .850" base circle camshafts. 

HIGH RPM! With today’s high engine rpm and increased rocker ratios, valve train life is extremely critical. Increased spring pressures are mandatory 

for insuring reliable valve train life. Contact Crower’s technical assistance department for proper high rpm recommendations. 

INTEGRAL CAST IRON GEAR OPTION: Premium 8620 steel billet, copper plated cam cores with integral cast iron cam gear are available from 

Crower on a special order basis (specify part number 00050). Valve timing events are available online at: www.crower.com/valvtime.html

*86780 and 86781 retainers require Super 7° keepers. Titanium valves required to achieve 

high rpm. 

Due to the wide variety of valve train combinations (i.e. lifter bore diameters, offsets, valve 

lengths, installed heights, etc...), we highly recommend that you contact Crower for your 

specific valve train needs. 

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. For strokes of 3.900" or larger contact 

Crower for .850" base circle camshafts. 

HIGH RPM! With today’s high engine rpm and increased rocker ratios, valve train life 

is extremely critical. Increased spring pressures are mandatory for insuring reliable 

valve train life. Contact Crower’s technical assistance department for proper high rpm 


INTEGRAL CAST IRON GEAR OPTION: Premium 8620 steel billet, copper plated cam cores 

with integral cast iron cam gear are available from Crower on a special order basis (specify 

part number 00050). 

HIPPO Note: For severe duty roller lifter applications, we highly recommend using our roller 

lifters with Hippo “High Pressure Pin Oiling”. Specify “H” in the part number.

CROWER CAM BREAK-IN PROCEDURE 

This applies to all hydraulic and solid lifter camshafts using higher than stock spring pressure: 

•Do not use block restrictors in the oil galleys. This severely limits oil flow to the 

cam, lifters and overhead. 

•Break-in cam and lifters with low pressure springs only. Do not exceed 225 to 

250 lbs open pressure. 

•During break-in run engine for 35 to 45 minutes and vary rpm from 2000 to 3000. 

•Recommend adding Engine Oil Supplement (EOS) or equivalent to fortify oil. 

Use Crower #86084. 

•For break-in procedure only, Crower recommends 10W/30 motor oil. Heavier weight 

oils do not cold flow. 

•Do not use synthetic oils during break-in period. 

•For further information, please refer to the Crower Installation booklet.

excellent low end and mid-range power and extended rpm range for 

spirited street and off-road driving. A perfect combination of mileage and 

power. Modifications should include small diameter tube headers, low 

restriction dual exhaust, aftermarket manifold, increased cfm carburetor 

and reworked or performance ignition. Increase in compression ratio to 

9.5:1 is recommended for maximum output. 

Works well with automatic transmission or 4-speed. 

RPM Power Range: 1300-1500 to 4000-4200 / Redline: 5500 plus.

HIGH PERFORMANCE COMPU-PRO / Performance Level 3 - Intended 

for the performance oriented hot street application. These cams offer an 

extended rpm range with emphasis on upper bottom to top end power 

(strong mid-range). Performance gears, headers, dual exhaust, larger than 

stock cfm carburetor, performance manifold and increased compression 

(9.5:1 to 10.5:1) are required. Works well with automatic transmission if 

matched with proper ring and pinion gears and/or high stall converter.

IMPORTANT! Stock big block Chevrolet 

single springs are designed for cams with 

approximately .400" lift. When stock valve 

springs are used with performance cams 

over .400" lift, coil bind and retainer to 

valve guide interference will occur. 

Note: Rocker arms available in Aluminum 

& Stainless steel. 

BE SMART! Crower performance camshafts feature high lift, fast action features that can cause stock or other aftermarket valve train components to fail. 

Be sure to use a Crower engineered kit to avoid possible damage. CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve 

guide clearance at full lift (minimum .050"). Do not exceed .550" gross lift using stock rocker arms. 

Note: Early 348-409 cid 1958-1965 cam cores are available from Crower on a special order basis.

Flo” head design delivers a significant increase in cylinder head flow figures, 

while the tip area is hardened to RC50, including past the critical keeper groove 

area for added strength. Fully CNC machined and swirl polished to insure that 

you will get the best performance valve available on the market. Choose from 

standard and 1mm oversize. Titanium valves also available.

ADJUSTABLE SPROCKETS 

Crower's new cam sprockets are made from premium 6061-T6 

billet aluminum and incorporate a four bolt ARP® fastening 

system to prevent the slippage found in other brands. For the 

ultimate tuner, Crower sprockets feature 5/16" diameter, 12 

point ARP® fasteners with a hardened washer to prevent galling 

and stripping. The lightweight design reduces unwanted 

harmonics which could cause valve train failure.

Note: If your installed height does not fall withtin these dimensions, contact 

Crower for a recommendation. 


Note: If using Boss heads contact the Crower for special spring and retainer recommendations. 

Boss 302 engines employ a 1.73 rocker ratio, so the gross lifts 

will change for the Boss 302. To figure the correct gross lift for Boss 302 heads 

divide the gross lift listed by 1.6 (lobe lift) then multiply the lobe lift by 1.73 (Boss 

302 rocker ratio). 

Note: Camshafts for 289/302 cid engines can be used in 351W engines by changing 

the firing order to 1-5-4-2-6-3-7-8. 

Some early Ford heads use 5⁄16 valve stems. Please specify when ordering as the 

above kits are designed for 11⁄32 stems. 

CAUTION! When using high lift cams pay close attention to retainer, oil seal and 

valve guide clearance at full lift (minimum .050"). Valve timing events are available 

online at: www.crower.com/valvtime.html

68670S-16 Seat: 1.900" @ 180 lbs / Nose: 1.200" @ 654 lbs / Coil bind: 1.010" 


Note: If using Boss heads contact the factory for special spring and retainer recommendations. Boss 

302 engines employ a 1.73 rocker ratio, so the gross lifts will change for the Boss 302. To figure the 

correct gross lift for Boss 302 heads divide the gross lift listed by 1.6 (lobe lift) then multiply the lobe 

lift by 1.73 (Boss 302 rocker ratio). 

Note: Camshafts for 289/302 cid engines can be used in 351W engines by changing the firing order 

to 1-5-4-2-6-3-7-8. 

Some early Ford heads use 5⁄16 valve stems. Please specify when ordering as the above kits are 

designed for 11⁄32 stems. 

CAUTION! When using high lift cams pay close attention to retainer, oil seal and valve guide clearance 

at full lift (minimum .050").

REMEMBER! 

When installing new camshaft please remember that the contact surface of the follower must be free of 

wear/smooth surface. 


Crower's new cam sprockets are made from premium 6061-T6 billet aluminum and incorporate a four bolt 

ARP® fastening system to prevent the slippage found in other brands. The lightweight design (327g) reduces 

unwanted harmonics which could cause valve train failure. To have the full potential of your cam performance, 

cam sprockets are required. 


Made from the highest grade stainless steel, this Crower valve is a must for high horsepower, 

high boost and high rpm applications. The exclusive “Pro Flo” head design delivers 

a significant increase in cylinder head flow figures, while the tip area is hardened to RC50, 

including past the critical keeper groove area for added strength. Fully CNC machined 

and swirl polished to insure that you will get the best performance valve available on the 

market. Choose from standard, 1/2mm, 1mm oversize. Titanium valves also available. 

Note: Valve guides may require honing to size. All Crower VTEC valves are 5.5mm 

stem diameter. Factory guides may vary depending on specific engine.

As of last count we have accumulated 

over 80 different combinations of proven 

drag racing cam profiles and lobe center 

configurations. So rather than list each 

profile and lobe center, we felt that it 

would be more beneficial to encourage 

you to call our experienced technical 

support staff with your accumulated data 

and specifications. In a joint effort, that 

will be kept in the strictest of confidence, 

we will formulate the right combination 

of intake and exhaust lobe characteristics 

designed specifically for your application. 

We are currently involved with some of 

the top racers and engine builders and are 

achieving tremendous success with this 

style of format.

critical keeper groove area for added strength. Fully CNC 

machined and swirl polished to insure that you will get the 

best performance valve available on the market. Available

increased cfm carburetor and reworked or performance ignition. 

Increase in compression ratio to 9.5:1 is recommended for maximum 

output. Works well with automatic transmission or 4-speed.

CAMSHAFT REGRINDS 

If you’re lacking performance, send Crower your used or damaged 

camshaft for complete lobe analysis and regrinding or repair. Cams will 

be straightened and then checked-out (sample shown above) to establish 

original specs. A Crower technician will analyze all of the data and, based 

on your performance parameters, regrind your cam to desired specs. 

Description 

#1 TOURING PROFILE (250F) 

(Solid Lifter) Improves entire rpm range from 1000 to 6000. 

Smooth idle. Stock applications with no more than 10.5:1 

compression. 

#2 RALLY SPORT PROFILE (264F) 

(Solid Lifter) Slight lope at idle. Improves rpm range from 1500 to 

6500. Greatly improves high gear acceleration for passing and hills. 

#3 SLALOM/AUTOCROSS PROFILE (270F) 

(Solid Lifter) Slight lope at idle, but smooth into the throttle. Improves 

rpm range from 2000 to 6700 plus. More power for passing and hills. 

#4 CLUB RACER PROFILE (284F) 

(Solid Lifter) Racy lope at idle. Extends rpm range from 2500 to 6500 

with redline at 7100 plus. Increased compression, valve pocketing 

in combustion chamber and added carburetion will enhance total 

power. 

#5 COMPETITION PROFILE (290F) 

(Solid Lifter) Race only. Very rough idle, especially with added 

carburetion. Higher compression pistons or head milling advised as 

peak horsepower develops in 5500 to 6500 rpm range. 

#6 ROAD RACING PROFILE (304F) 

(Solid Lifter) Race only. Requires extensive modifications like 13:1 

compression, grouped exhaust system, individual carburetion, inlet 

valve pocketing and engine balance. Rpm range from 4500 to 8000.

CAMSHAFT BUSHINGS 

Using Crower camshaft bushings is 

the easy way to “tune” your camshaft 

timing. You’ll receive five advance or 

retard bushings that are individually 

stamped to display amounts advance/retard 

in cam degrees (0°, 1°, 

2°, 3°, 4°). Features a shouldered lip 

that retains the bushing and eliminates 

fallout.

LIGHTWEIGHT 

FUEL PUMP PUSHROD 

The Crower fuel pump pushrod is 

manufactured from lightweight steel 

tubing that is heat-treated for added 

strength. The bronze tip insures proper 

surface mating with the fuel pump 

eccentric lobe on 8620 steel billet 

camshafts. This surface compatibility 

eliminates the wear problems associated 

with stock designs. For cast iron 

hydraulic and solid cams we offer a 

lightweight model with a steel tip at 

each end to protect against wear.

CAM THRUST PLUGS 

Roller cam lobes are ground flat, 

without the taper found in hydraulic 

and solid lobes. The cam thrust plug 

sits between the front of the timing 

gear and the back of the front cover 

and prevents forward cam travel and 

ignition flutter in roller grinds. Available 

in choice of two styles: phenolic 

(non-galling material) or fully rollerized 

for reduced friction.

CAMSAVER HYDRAULIC LIFTERS 

The maximum in cam lobe and lifter life. 

If high spring pressures or extreme and 

unusual operating conditions have you 

worried about lobe scuff and lifter wear, 

insist on Crower “high-lube” CamSaver 

lifters. These lifters deliver 20% to 30% 

more oil to your lobe and lifter faces 

for the best possible insurance against 

premature lobe and lifter failure. Specially 

machined flats put 12 to 16 ounces 

of additional oil per minute at each lobe 

without adversely affecting engine oil 

pressure (nominal drop of just 1 or 2 

pounds). Crower CamSaver lifters incorporate 

the same precision ground radius 

face and finish as our standard lifters to 

insure quick break-in and trouble 

free operation.

CROWER EDM OILING 

Electronic Discharge 

Machine allows Crower 

engineers to place precision 

holes without the use of a 

drill bit. Delivers more oil to 

critical, high load areas. 

With today’s high rpm, high rocker ratio 

and high spring pressures, cam and lifter 

failure is at an all time high. Crower’s all new 

“CoolFace” lifter option is a must for these 

applications. Features a small diameter 

oil metering port (.024") that is precision 

machined in the face of the lifter. No 

significant oil pressure loss, but significantly 

improved cam and lifter longevity. 

Crower has a complete inventory 

of .842", .874", and .903" diameter lifters 

to choose from, including piddle valve, 

edge orifice, small chamfer, no chamfer and 

lightweight designs. Call Crower for pricing 

and availability. Crower also offers the 

“CoolFace” option on competitor’s solid lifters 

as well. Send your competing brand lifters in 

to Crower for precision EDM machining.

Lifters – Roller 

Precision ground oil metering 

holes deliver plenty of oil flow 

to the overhead, vital for longer 

pushrod and valve spring life. 

Captive blades are secured 

with Crower’s exclusive 

orbit formed locking 

mechanism for permanent 

spool attachment. 

Crower’s “beefy” blades 

are made from premium 

steel alloy to insure 

the absolute strongest 

fastening system 

available. 

Crower rollers are 

available in all popular 

designs (full body and 

cutaway) as well offsets, 

body diameters. 

HIPPO 

(High-Pressure Pin Oiler) 

Hi-Pressure Pin Oiler allows Crower engineers to place a 

precision .024" hole directly from the oil band to the needle 

bearings. Delivers more oil to critical, high load areas for 

greatly improved cycle life. Specify “H” after lifter part 

number to order (ex. 66200H-16). 

HIPPO oiling features 

.024" oil metering 

hole that delivers 

plenty of lubrication 

to the needle 

bearings and pin. 

Redesigned bearing slot 

provides more shrouding 

around critical bearing 

area reducing tappet and 

lifter bore wear. 

Utilizes longer, “control 

contoured” tapered needle 

bearings that deliver 

unsurpassed load capacity and 

correct for irregular tappet 

alignment. 

Crower roller lifter tappets 

feature crowned bearings 

and crowned outer race 

that greatly reduces lobe 

tracking. 

Integral one piece body 

reduces weight without 

compromising strength 

and delivers the utmost 

in rigidity and axle 

trueness. 

CNC machined, heattreated 

body for best 

possible wear resistance. 

Unique orbit formed pin 

eliminates snap rings that 

could come loose.

in achieving proper valve train 

geometry. Crower precision checking 

pushrods guarantee accurate 

measurements for determining the 

optimum pushrod length. Precision 

crafted from steel alloy with a black 

oxide finish for added durability, 

Crower checking pushrods are 

extremely easy to use. Each complete

lightweight aluminum alloy bars, 

spacers, and springs required for 

quick and easy installation. Available 

for both standard and cutaway 

design Crower roller lifter tappets. 

Cutaway designs must specify intake 

and exhaust rocker offsets.

Crower pushrods. All 

ends are heat-treated to a 

surface hardness of RC60 

for maximum durability 

and wear resistance. 

Crower’s standard pushrod 

design features an end-totube 

spot weld fastener 

for extended use. For 

severe duty or guide plate 

applications see our vast 

assortment of RC60 Series 

pushrods. 

ADJUSTABLE PUSHRODS 

When going from hydraulic 

to solid lifters, adjustable 

pushrods are often required 

if there is no adjustment 

provision at the rocker 

arm. The overall length of 

Crower adjustable pushrods 

is listed with adjustable 

end in the middle of the 

adjustment range. 

NON-ADJUSTABLE 

PUSHROD KITS 

Non-adjustable pushrod 

kits include the following: 

• 16 non-adjustable 

pushrods (1⁄4" longer than 

stock) with one end out. 

• 16 pushrod ends. 

• One adjustable pushrod 

(two if intake & exhaust are 

different lengths).

CUSTOM LENGTH 

PUSHRODS 

Crower is one of the 

world’s largest producers 

of custom pushrods and 

can fabricate a pushrod 

set for any engine make. 

Specify overall length, tube 

diameter, tube strength and 

type of ends you require. 

Three piece pushrods are 

available on a special order 

basis. 

CORRECT VALVE TRAIN 

GEOMETRY 

Correct pushrod length is 

critical in achieving proper 

valve train geometry. 

When measuring pushrod 

lengths, be sure to consider 

any head or block milling. 

We recommend using 

a checking pushrod 

for the most accurate 

measurement (refer to 

pushrod accessories 

located later in this section). 

ORDERING 

When ordering Crower 

pushrods, please include 

the part number, cubic 

inch, model, make and year 

of engine, type of rocker 

arm and lifter used, as well 

as the overall pushrod 

length, tube diameter, tube 

strength and type of ends 

desired. This information 

is critical in order to 

manufacture the correct 

pushrods required.

Rocker Arms 

Back in 1957, Crower 

pioneered the very first 

shaft rocker arm assembly 

mounted on a stock small 

block Chevy cast iron 

cylinder head. The race was 

the Indy 500 and Crower 

has been making high quality rocker arms ever since. 

The weak link in any pushrod engine is the rocker arm 

and rocker arm flex. Eliminating flex is an important 

factor toward developing maximum horsepower. Crower 

has made significant improvements toward perfecting 

shaft rockers for use in high performance engines. 

Over the decades of working with you, the racers and 

engine builders, we’ve learned to study the problems 

you encounter. We’ve made note of your wish lists. 

We’ve scrutinized failed components...done our home 

work! Consequently, we’ve been able to offer solid, 

viable, cost effective solutions that do not compromise 

strength. You’ll find that all our stud and shaft mount 

rocker arm systems achieve the critical balance of 

weight considerations without compromising 

enduring strength. Crower valve train components 

are characteristically strong, able to maintain 

dimensional integrity under load and at high 

rpm so valve actuation is extremely accurate. 

Our rocker systems are well thought-out with 

regard to proper geometry, minimizing friction 

and heat build-up so the parts live and rpm 

freely. The shaft setups are user friendly so 

they are easy to work on at the track and 

provide accurate, repeatable valve adjustment. 

Crower rocker systems (stud or shaft mount) 

are available for most popular cylinder heads, 

often in your choice of material, stainless steel 

or aluminum. Crower Cams & Equipment Company... 

aero space materials, state-of-the-art production 

facilities and savvy engineers solving problems with 

creativity, technology and common sense. The 

result? The finest valve train componentry you can 

equip yourself with! You’ll find no better rocker 

systems available at any price!

Anatomy of a 

CROWER ROCKER 

Our 2024 aluminum bodies 

deliver maximum strength at operating 

temperature. 

Our lash adjusters are machined from aircraft quality 

Hi-temp alloy, precision thread rolled after double 

heat treat process. 

Aircraft quality 

12 point nuts. 

Hardened tip wheel 

withstands race 

rigors and minimizes 

scrubbing. 

Needle Bearing Tip Option 

Crower has raised the bar on 

valve train technology with a new 

needle bearing roller tip option available 

on all new Crower stud and shaft 

mount rocker arm assemblies. 

Specify 

#73715R after rocker 

part number for stainless 

steel, #72915R for 

aluminum. 

Results are greatly reduced 

friction for added horsepower and 

reduced valve guide and valve stem 

The lighter tip delivers greater valve 

control for increased rpm and improves valve 

spring longevity by decreasing heat over 

traditional non needle designs. 

Our Axles are “super secured” for 

trouble free operation. 

Fully rollerized precision 

needle bearing fulcrum. 

Crower shafts are CNC 

precision machined 

from ball race alloy 

steels, heat-treated 

twice and micro finish 

ground in-house. 

Ideal rocker 

geometry at 

half valve lift 

Highest unit loading 

on the valve train is approximately at 

half lift (45° @ cam lobe) 

This configuration minimizes 

tip travel across the 

valve stem and keeps contact 

centered on top of the 

valve, reducing frictional 

losses due to valve guide 

side loading and tip scrubbing. 

Pushrod deflection 

is also minimized for more 

accurate valve action. 

Rocker Ratio 

Rocker arm ratio is 

determined by dividing 

the distance from 

the fulcrum to the tip 

centerpoints (Y) by 

the distance from the 

fulcrum to the pushrod 

seat centerpoints (X). 

This theoretical ratio 

may vary from our net/ 

advertised ratio due to 

measured valve train 

deflection under load. 

Long Arm 

Higher rocker ratios 

require extending the 

arm of the rocker. Long 

arm rockers allow proper 

pushrod seat positioning 

in relation to the fulcrum 

point. An additional long 

arm benefit is reduced 

back and forth tip travel 

across the valve stem. Less 

scrubbing and valve stem 

side loading occur and 

associated frictional losses 

are minimized. 

Tip Travel 

No Lift 

contact slightly behind centerline 

When the valve is closed tip 

contact is slightly behind the 

centerline of the valve. 

Half Lift 

centerline contact 1/2 lift 

At highest unit loading (approx. 1/2 lift) tip contact ideally is 

on the centerline of the valve. The valve train is overcoming 

spring pressure and, more importantly, rapidly accelerating 

its mass. To minimize deflection, side loading and frictional 

loss, we want the valve train geometry in its strongest and 

straightest configuration at this point. 

Full Lift 

contact slightly behind centerline 

When the valve is open, tip contact is slightly behind 

the centerline of the valve. The valve train in this 

position (at high RPM) feels the least amount of 

unit loading as float approaches...everything gets 

momentarily weightless.

Determining Which Crower Shaft 

Rocker System Fits Your Needs 

If you’re not sure or don’t know which Crower 

Shaft Rocker System will fit your cylinder head, or 

the type/model of head you have and need help, 

follow these simple procedures: 

1. You’ll need to provide us with some critical 

information and dimensions. 

a. Cylinder head manufacturer 

b. Engine type 

c. Intake and exhaust valve distances from 

cylinder head centerline. 

d. Rocker stud spacing from cylinder head 

centerline. 

Here’s how you do it. 

Measure the distance between the centerlines 

of the two inboard exhaust valves and record the 

value. If you divide this measurement in two you’ll 

know the distance each valve is from the cylinder 

head centerline. 

Now measure the distance between the 

centerline of the exhaust valve and the centerline 

of the intake valve.

Results are greatly reduced friction for added horsepower and reduced valve guide and valve stem wear. The 

lighter tip delivers greater valve control for increased rpm and improves valve spring longevity by decreasing 

heat over traditional non needle designs. Specify #73715R option for stainless steel (stud or shaft) or #72915R

Shaft-Mounted Rocker Arms 


For those of you that feel most confident running 

a steel based valve train, we offer you the 

Crower collection of shaft mounted stainless 

steel rocker arms. Each and every configuration 

has been religiously scrutinized to offer 

extreme rigidity and accuracy while optimizing 

moment of inertia phenomena condition. 

Crower engineers made ease of installation 

and maintenance a top priority so you’ll never 

waste a moment when time is critical at the 

track. Our stainless steel shaft rocker systems 

are a perennial favorite of dirt late models and 

marine endurance competitors. Sustained high 

temperature has little affect on the strength 

properties of stainless steel so components 

made from this material should have a longer 

life expectancy than similar components made 

from aluminum.

All Crower stud and shaft mount rocker arms are available with 

Crower’s new needle bearing roller tip option. Results are greatly 

reduced friction for added horsepower and reduced valve guide 

and valve stem wear. The lighter tip delivers greater valve control for 

increased rpm and improves valve spring longevity by decreasing 

heat over traditional non needle designs. Specify #73715R option for 

stainless steel (stud or shaft) or #72915R option for aluminum (stud 

or shaft) when ordering rocker arms.

Each of our Aluminum Shaft Rocker 

configurations is impeccably designed 

and produced to maximize valve train 

rigidity and accuracy while offering a 

minimal amount of reciprocating mass. 

We have utilized the longest arm 

lengths practical for each application. 

The results are minimal rocker tip 

travel and associated frictional 

losses as well as the capability to 

accommodate large diameter valve 

springs with ease. 

Speaking of ease, these set-ups 

allow for the quickest at-the-track 

valve train modifications around. Any 

task that requires rocker removal can 

be performed without concern for 

absolute accuracy and repeatability 

upon reassembly.

LASH CAPS 

Crower lash caps protect the ends 

of your valves from excessive wear 

and help to correct rocker geometry 

by increasing rocker arm to retainer 

clearance. Machined from high 

grade chromoly steel and heattreated 

for added strength, Crower 

lash caps give your valves an added 

.060" margin of protection. Highly 

recommended for performance 

applications, and a must for costly 

stainless steel or titanium valves. 

Also available in singles by replacing -16 with -1. 

BILLET PERFORMANCE 7° 


Crower billet performance valve stem

Connecting Rods 

THE CROWEROD DIFFERENCE 

An extensive effort in CAD (Computer Assisted Design) & F.E.A (Finite Element 

Analysis), as well as rigorous dyno and track testing have been expended 

through perfection of our strongest yet lightest rods available. When you 

employ a set of genuine Crowerods you do so with the knowledge and 

peace of mind that each rod will perform flawlessly. That’s why they are 

hands down, the favorite of professional and amateur engine builders 

throughout the world. 

IT’S THE MATERIAL... 

While other manufacturers are 

cutting corners, using inferior 

or low grade materials, Crower 

has kept costs down without 

lowering our standards. 

Crowerods incorporate only 

the finest aircraft quality steel 

and titanium materials. They are 

heat treated to obtain that perfect 

balance of strength and durability , 

to insure the best quality and 

reliability possible. 

AND THE DESIGN 

Take a close look at a Crowerod and you’ll notice that it is shaped like no other 

rod in the industry. Every contour is designed to enhance overall strength and 

reliability at high engine rpm. Crower connecting rods incorporate an “I-beam” 

design that eliminates pockets of excess material and delivers exceptional 

longitudinal and horizontal strength. The cap screw design assures true 

roundness and a positive bearing seat under severe load factors, in which 

eliminating rod bearing failure. Tolerances are to an exacting ±0.0001" of an 

inch to insure trouble free installation. For those who prefer an “H-beam” 

design, Crower also offers this style of rod on a custom order basis. 

CROWER, your # 1 source for rods. 

CROWER makes rods for 

almost any application. 

THE BOTTOM LINE 

When you install a set of genuine Crowerods in your high performance engine, the design expertise, material and 

craftsmanship are working hard to maximize your racing effort. It’s the kind of dependability and confidence that 

can put you in the winner’s circle. Crowerods are available for most domestic and foreign applications, as well as 

motorcycles, industrial, vintage and one of a kind prototypes. Our Crowerod design is often imitated, but never 

duplicated. For any new enthusiast we have an excellent staff that can help you on any particular design you may 

want. Protect your investment by insisting on only genuine Crowerods for your high performance needs.

“RBT” Steel Billet Connecting Rods 

Aircraft quality, 12-point cap 

screw fastening system provides 

added security at high rpm. 

Crower’s all new Radial Beam Technology design ( “RBT” ) is the 

ultimate connecting rod, often copied by competitors, but never 

replicated to Crower's engineered standards. The radial shape 

beam delivers unsurpassed beam support while reducing overall 

weight for greater throttle response...quicker deceleration into 

the corner and faster acceleration off the corner. 

Drilled and chamfered pin oil 

hole on all Crowerods provides 

additional oil at the pin end to 

prevent galling. The high alloy, 

aluminum-bronze, one piece 

bushing delivers long, reliable 

service. 

H11 - Tool Steel bolts rated to 

220,000 p.s.i. come standard. 

For extreme duty, Crower highly 

recommends the AMS5844 rod 

bolt upgrade rated to 280,000 p.s.i. 

for ultimate clamping ability. 

Extra strength at the critical web area 

reduces the big end pinch found 

in other inferior designs. Big end 

roundness is paramount for long 

bearing and connecting service. 

Pin boss dynamics are essential 

when designing a high 

performance connecting rod. To 

maintain trouble free operation, 

Crower beefs up the pin eye area. 

The Crower Maxi-Light is a 

proven performer on the race 

track. Tapered beam design 

delivers the strength you need in 

a lightweight, yet reliable profile. 

Hollow dowel alignment 

fastening system provides 

positive cap alignment and 

prevents unwanted cap walk. 

RADIAL BEAM TECHNOLOGY (“RBT”) 

MAXI-LIGHT DESIGN 

Crower’s exclusive “RBT” Maxi-Light design is a 

revolutionary new beam shape that removes excess 

material from noncritical stress areas for the lightest, 

yet strongest connecting rod available on the market. 

Choose from a wide variety of weight configurations, 

depending on your individual horsepower and rpm 

requirements. 

AMS5844 ROD BOLT UPGRADE 

Crower’s AMS5844 rod bolt upgrade is available 

for all steel billet and titanium rods. Highly 

recommended for extreme duty rpm 

and endurance applications. Rated at 

280,000 p.s.i., these bolts are corrosion 

resistant, nonmagnetic and deliver 

ultimate clamping capabilities for the 

highest cycle life. Specify desired rod bolt 

part number when ordering. 

Proper bolt torque: Torque rod bolts to 10 ft lbs on both sides, 

then torque to proper spec with one pull. 

Upgrades: 280,000 p.s.i. rod bolts, specify #90842 for 3⁄8

STEEL BILLET ROD WITH 12 POINT CAP SCREW BOLT 

Unquestionably the most critical part of a high performance, internal combustion 

engine is the connecting rod. Connecting rods support the primary tension loads 

caused by engine operation in each revolution or cycle of the crankshaft. Therefore, 

it is of utmost importance that the rods you choose to put in your engine are made 

from only the finest quality materials, manufacturing methods and fastening systems 

available on the market. For over 30 years, Crower has been 

meeting this challenge by using the finest quality steel in 

the production of our steel billet connecting rods. Every rod 

is fully CNC machined to remove all surface imperfections, 

100% magnaflux inspected, checked for hardness and then 

machined to finalize the exact tolerance within 0.0001" of an 

inch. Each set of rods is fully balanced and then shot peened 

to achieve the ultimate in strength and reliability. Choose 

from premium H-11 tool steel rod bolts or available as an 

upgrade, AMS5844 bolts. 

An assortment of computer 

designed beams are available 

for different horsepower and 

weight requirements. 

Crower’s RBT beam features 

a radius beam design for 

the utmost in strength 

capabilities while reducing 

overall weight of the rod for 

improved throttle response. 

Drilled and chamfered 

pin oil hole on 

Crowerods provides 

additional oil at pin 

end to prevent 

galling. Available in 

aluminum/ bronze 

bushed or pressed 

fit pin. 

Pin boss dynamics 

are critical when 

designing a high 

performance 

connecting rod. To 

maintain troublefree 

operation, 

Crower beefs up the 

pin eye area. 

CROWER H-BEAM DESIGN 

Hollow dowel alignment 

fastening system provides 

positive cap alignment and 

“no hassle” removal. 

Integrally threaded beam 

can be made to accept 

bolt diameters of 5⁄16, 3⁄8 

and 7⁄16. 

Deep, double-ribbed 

cap guarantees 

superior strength 

and reliability at high 

engine rpm. 

Only Crower offers you, the engine builder, 

the choice of “I-Beam or H-Beam” design. 


Crower’s AMS5844 rod bolt upgrade is 

available for all steel billet and titanium 

rods. Highly recommended for extreme 

duty rpm and endurance applications. 

Rated at 280,000 p.s.i., these bolts are 

corrosion resistant, nonmagnetic and 

deliver ultimate clamping capabilities 

for the highest cycle life. Specify desired 

rod bolt when ordering. 

Proper bolt torque: Torque rod 

bolts to 10 ft lbs on both sides, then 

torque to proper spec with one pull. 

Extremely reliable H-11 

tool steel bolts, rated at 

220,000 p.s.i. or aircraft 

quality, AMS5844 alloy 

bolts that are corrosion 

resistant and rated at 

280,000 p.s.i. Both feature 

12-point heads. 

MAXI-LIGHT DESIGN 

CROWER “H-BEAM” CONNECTING RODS 

Although Crower is known mostly for it’s “I-Beam” rods, we also build a variety 

of European influenced “H-Beam” designs as well. The thicker cross sections 

of the H-Beam are better suited for the EDM oil hole that runs the length of 

the beam delivering added oil to the pin. Weights are equivalent to Crower’s 

standard “I-Beam” billet rod. Specify H-Beam when ordering. For Pressure Fed 

Pin option specify #90798 after rod part number.

bolts to 10 ft lbs on both sides, then

Titanium Connecting Rods 

TITANIUM RODS 

Crower uses only aerospace quality, 

titanium in the manufacturing 

of our billet Crowerods. Titanium 

has a lower thermal expansion 

rate than steel and much less than 

aluminum, which allows the racer 

to hold closer tolerances within the 

engine. Crower offers a wide variety 

of applications. Everything from a 

4 cycle motorcycle to a 8" long big 

block Chevrolet for Pro Modified. All 

Crower titanium connecting rods 

are equipped with cap screw 

bolts and stroker designed to 

insure plenty of camshaft 

and case clearance, also 

reducing weight in 

noncritical areas. 

Special “pressure fed” oiling hole from big 

end to pin end is available on all titanium 

and premium steel billet Crowerods. 

Specify this option when ordering. 

All titanium rods come 

standard with aluminum/ 

bronze bushings. 

Crower uses only titanium, 

with a composition of 6% 

aluminum and 4% vanadium. 

Custom rods available in 

most center to center pin 

end size and big end I.D. 

Crower is a complete 

production facility. 

Every step of manufacture 

is performed under rigid 

quality control standards 

Hollow dowel alignment fastening 

system provides positive cap 

alignment and “no hassle” removal. 

Special plasma sprayed sides 

prevents galling that occurs 

when titanium rubs with steel. 

Extremely reliable H-11 tool steel 

bolts, rated at 220,000 p.s.i. or 

aircraft quality, AMS5844 alloy 

bolts that are corrosion resistant 

and rated at 285,000 p.s.i. Both 

feature 12-point heads. 


Crower now offers a new AMS5844 rod 

bolt upgrade option available for all 

steel billet and titanium rods. Highly 

recommended for extreme duty 

rpm and endurance applications. 

Rated at 280,000 p.s.i., these bolts 

are corrosion resistant, nonmagnetic 

and deliver ultimate clamping capabilities 

for the highest cycle life. Be sure and specify 

upgrade option when ordering.

STROKER 

Separate 

forging dies 

for each 

length (5.7" 

and 6.0") to 

establish 

better grain 

flow. Lesser 

designs try 

and get by 

with just 

one die 

for several 

lengths, then 

cut to size. 

Stroker 

design 

offers more 

cam-to-rod 

clearance 

and is 

intended 

for strokes 

of 3.750" 

and up. Can 

also be used 

in shorter 

stroke 

engines if 

7⁄16 bolt is 

desired.

THRU-BOLT 

3⁄8 aircraft quality, 

8740 chromoly steel 

thru-bolt and nut 

adheres to O.E.M. stock 

specs, making it stock 

legal for all major 

sanctioning bodies. 

Properly engineered small end 

guarantees long, reliable pin 

alignment. Available in bushed 

aluminum/bronze or pressed fit pin. 

Stroker design utilizes a 

larger 7⁄16 cap screw bolt 

for ultimate clamping 

ability (#90846). 

Ribbed cap delivers 

distortion free 

performance at high 

horsepower and rpm. 

Experienced engine builders 

know that heavy rods are 

notoriously hard on the wrist 

pin area. Crower reduces 

unwanted loads by minimizing 

overall weight.

SPORTSMAN® THRU-BOLT 


First introduced back in 1987, 

the Crower Sportsman rod was 

the original high performance 

stock replacement rod. 

Features traditional thru-bolt 

and nut fasteners for stock 

legal classes. All Sportsman 

aircraft quality rods are forged 

from two separate dies, each 

dedicated to a specific length 

(5.7"/6.0"). This forms a 

more uniform molecular 

grain flow for a stronger, 

more reliable rod than 

other brands using one 

die for several lengths, 

then cutting to size. 

Includes 3⁄8 8740 bolts and 

nuts (180,000 p.s.i.). 

If Pressed Fit Pin desired, replace “B” after p/n (ex. SP93200PF-8). 

For Cosworth Vega, use #SP93208B-4

Crankshafts 

A TYPICAL SCENARIO 

For years you’ve been running a stock crank and have 

never experienced rod bearing failure. You decide to 

“step-up” and replace your stock crank with an aftermarket 

brand. Immediately you encounter bearing scuff or total 

bearing failure. This scenario happens often, much to the 

dismay of the engine builder. 

Looking from the rod, back up through 

the main, you can see daylight, indicating 

it’s a genuine Crower crankshaft with the 

“straight-shot” oiling system. 

The unique teardrop scoop and exclusive 

Crower “straight-shot” oiling system 

increases critical oil flow from the main 

bearings to the rod bearings. 

Entry holes for the rod feed are located at 

the O.D. of the main, allowing oil to flow 

equally and unrestricted to the bearings. 

This is key to prolonging bearing life. 

THE PROBLEM 

On most aftermarket 

brands the rod feed 

hole is only drilled to 

the centerline of the 

main. This method 

of drilling doesn’t 

deliver enough oil 

to the rod . Creating 

a high centrifuge, 

high pressure 

zone at the main, 

restricting critical 

oil flow intended for 

your rods. As engine 

rpm increases this 

centrifuge effect 

gets worse, possibly 

resulting in severe 

crankshaft damage 

or even total engine 

destruction. Not 

the performance 

characteristics you 

expected when 

you switched to an 

aftermarket brand 

crankshaft. 

THE SOLUTION 

STRAIGHT-SHOT OILING 

After extensive 

research and design, 

Crower engineers developed the straight-shot oiling system 

and virtually eliminates bearing burnout and customer 

complaints. It features two Crower exclusives, off-center 

drilling and the teardrop design oil hole, which scoops oil at 

the main and forces it into the rod feed hole. Although it’s 

time consuming, we feel it’s worth it. 

THE PROVEN FACTS 

It has been proven time and time again, “the lighter the 

parts, the quicker the throttle response.” This is no more 

evident than in the components that make up the bottom 

end of an engine. Reducing a crankshafts counterweight 

mass is critical in getting quicker acceleration and 

deceleration. It also alleviates stress and engine wear and 

improves oil shearing in the pan. 

PENDULUM UNDERCUTTING AND 

LIGHTWEIGHT PIN WEB AREA 

Smaller O.D. design places heaviest 

mass closer to the center of the 

crankshaft for the quickest engine 

acceleration possible. 

Crower’s “counterweight 

correct” design produces 

optimum counterweight 

positioning for the best 

possible bearing loading 

and proper balancing. 

The shorter, 

narrower 

counterweight 

reduces total 

overall mass and 

has less frontal 

area. 

Crower’s exclusive lightweight 

crank pin web area allows 

the counterweights to be 

pendulum undercut to reduce 

weight without the need for 

heavy metal balancing on most 

applications. 

44.3% less frontal area 

improves windage and 

oil shearing in the pan, 

two external forces 

that frequently disrupt 

a crankshaft’s uniform 

motion. 

The “Klose’s Stress 

Concentration 

Reduction” distributes 

stress evenly over the 

entire overlap area. 

CROWER’S 

“Maxi-Light” 

REVOLUTIONARY DESIGN 

The Crower Maxi-Light crankshaft redefines the term “light 

rotating mass” by attaining just the right ratio of a smaller 

O.D. counterweight with an exclusive lightweight crank 

pin web area. By lightening the crank pin web area we are 

able to machine excess material from the center of the 

counterweights without adversely effecting balancing. This 

is Crower’s patented pendulum undercutting. Lighter than 

any other crankshaft like it on the market, the Maxi-Light 

is structurally just as strong and easy to balance. Although 

competing manufacturer’s claim to have comparable 

designs similar to the Crower Maxi-Light, consider the fact 

that it takes much more than just scalloping out the center 

of the counterweight to achieve the correct combination of 

light rotating mass and proper balance. Crower pioneered 

pendulum undercutting the counterweights back in 1989.

Rod & Main Bearings 

ROD BEARINGS 

Crower high performance rod bearings are 

quality engine bearings designed to withstand 

the extreme loads of professionally tuned 

racing engines. Features high strength trimetal 

copper-lead material in the load area for superior 

strength and embedding. Lead overplate 

provides excellent fatigue strength and superior 

conformability to compensate for distortion and/ 

or misalignment. Superlative bearing-to-bearing 

size consistency enables you to “build-in” the 

exact oil clearance you require, while narrowed 

and chamfered versions are available for large 

fillet journals where additional clearance is 

necessary. If running aluminum rods, Crower has 

chamfered rod bearings with dowel pin holes. 

MAIN BEARINGS 

Crower high performance main bearings offer 

professional racers and engine builders the 

extreme accuracy and bearing-to-bearing 

consistency required to build an engine that 

can handle the extreme loads associated with 

high performance racing. Features high strength 

copper-lead in the load area for superior strength 

and embedding. Crower high performance 

main bearings are designed to deliver improved 

bearing-to-bore contact for better heat transfer 

and a reduction in high rpm bearing chatter and 

or failure. Order chamfered bearings, for use with 

large fillet journals. A must when running any 

Crower crank.
