Welcome to Crow Cams

For over 30 years Crow Cams have maintained the most advanced cam development and CNC grinding facilities in Australia which have been used by car companies and our most successful racers to great effect.

Over the past 12 months Crow Cams have taken these facilities to the next level with new valve train simulation software developed to produce profiles that offer aggressive acceleration and maximum area under the cam without compromising valve spring lift or quiet valve train operation.

The new Crow Next Gen cam profiles deliver more .200 duration for improved mid-range power and torque over other cam profiles with similar 050 duration and lift. Crow Next Gen profiles are extremely smooth and accurate over the lobe nose to minimize stress on valve springs for improved service life.

Crow Cams' world class CNC grinding and inspection facilities have also been upgraded to ensure an even greater degree of grinding accuracy in terms of surface finish and cam position. These characteristics are checked on every cam on our CNC checking machines, which are regularly calibrated on our in-house Adcole camshaft coordinate measuring machine.

Many of Crow Cams' popular profiles have been redeveloped using the Next Gen process so even profiles you may have used for years will show noticeable improvements in accuracy and performance.

This technology applies equally well to Hydraulic cams, solid lifter cams, hydraulic roller cams and solid roller cams and in this catalogue you will see many new grinds to fully capitalize on the range of cylinder head and manifold options now available to you.

Our Products 

Next Gen Camshafts

Crow Cams' unique Next Gen cam design and CNC grinding technology is applied to a huge range of hydraulic lifter camshafts, solid lifter, camshafts, hydraulic roller camshafts and solid roller camshafts for maximum torque and power in street or race applications.

In addition to the huge range of profiles available in stock Crow Cams can custom grind a camshaft to you exact requirement using the free cam selection questionnaire on the website.

Next Gen Stainless Roller Rockers

Crow Cams' stud-type stainless steel roller rockers offer an unbeatable combination of strength, rigidity and value for money

With more aggressive cam profiles and heavier valve springs now common in street and race applications, the limitations of extruded alloy as a rocker material are clearly evident. The flex alloy rockers exhibit reduces valve lift and horsepower potential and the stresses can lead to arm failure.

These problems have lead to a move to steel rocker arms in the upper levels of motor sport and now the strength and stiffness of steel is within the budget of every performance engine builder.

Crow Cams' new stainless steel stud type roller rockers offer virtually zero arm deflection for maximum valve lift and unrivalled resistance to arm breakage. The oversize rocker shafts allow for 7/16 studs to be used without comprising shaft strength. The larger shafts and needle roller bearings also offer greater load capacity for high valve springs pressures.

Every set comes complete with poly locks for added value and simple, secure valve lash adjustments. Crow Cams' screw in studs and guide plates will be required to fit these rockers to many factory cylinder heads.

Our Process

Over more than 30 years Crow Cams have developed unique camshaft grinding, inspection and finishing facilities using CNC technology to ensure the ultimate in product consistency and accuracy.

Every Crow Cam is ground using the highest quality cast iron or steel cam billets sourced from the leading suppliers in the USA and Europe. Prior to grinding every billet is straightened to correct any distortion that normally occurs in the heat treatment process.

Crow Cams is one of the few cam companies in the world who have in-house capability for cam lobe design and production. It is not well known that most cam companies simply copy existing profiles from companies like us who design their own profiles.

Crow Cams are ground on unique CNC controlled camshaft grinding machines developed in-house by our engineering staff. These machines computer control grinding speeds and feed rates to achieve exceptional accuracy and surface finish of the cam lobes.

Every cam is inspected in CNC controlled inspection equipment that checks every lobe for such critical element as lobe taper and base circle run out. Master cams are checked using the world’s most accurate cam inspection machine – the Adcole. We are the only Australian cam grinder to have such a machine in-house.

Camshaft surface finish is critical to long term durability and every cast iron cam goes through a phosphate and CNC buffing process. All steel roller cams are finished using a CNC lapping machine to produce a very fine cross hatch finish to ensure perfect roller lifter tracking.

Full cam specifications are supplied with every Crow Cams product, which are packed securely to arrive in perfect condition worldwide.

The same facilities and attention to detail that are applied to record setting race cams, for competitors such as 6-time Doorslammer champion John Zappia, are used on the Crow Cam you will receive for your road or race combination.
