                Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. COMP Cams® Steel Retainers are the perfect solution to this problem. COMP ® engineers used 3D CAD with FEA to design retainers with a modern and advanced contoured top profiling for lower stress, increased lift and a reduction in mass. The retainers are CNC-machined to exact tolerances using CAD/CAM software. All COMP ® retainers use only high-grade SAE 4140 chromemoly steel with no lead, <0.04% sulfur and a black oxide finish to prevent corrosion. COMP Cams ® Steel Valve Spring Retainers offer both unmatched looks and superior performance that set the industry standard.

    Speedway Small Block Chevy Solid Lifter Tight Lash Cam, 2750-6500 RPM
    x
                Speedway Tight Lash cams produce a broad range of power due to the short amount of cam degrees it takes to go from .020" lift to .050" cam lift. This is known as major intensity. The shorter the span the more torque the lobe will produce, and for the lobe to run excellent up at higher RPM, it must have an excellent area under the curve. You can tell these do because of the very high duration at .200" cam lift. 

    Compare our numbers to other cam profiles and you will find that these are far superior!

    For the enthusiasts who choose a solid lifter cam, COMP Cams offers the highest quality mechanical lifters available today. These lifters are manufactured using the tightest tolerances in the industry ensuring optimum performance. The crown of the lifter is ground to a precise radius for proper break-in and to guarantee long life. The oil metering band is milled to the correct depth to prevent too much oil from being delivered to the top of the motor, robbing precious horsepower. Remember, the lifter is the most important component between the cam profile and the valve, so make Comp Cams Solid Lifters your choice for maximum power and warranty protection.

    Probably one of the best kept secrets...the best engine builders use break-in roller rocker arms. With the extreme valve spring pressures racers use today, the initial run time can kill a camshaft in the first minute of running.

    The big time engine builders use these 1.3 ratio rockers to allow a run-in time for the camshaft, then the 1.3 rockers are removed and the normal rockers are reinstalled and the engine is ready to race or dyno.

COMP Cams has answered the challenge with the new Oil Injection solid mechanical lifters that feature a precision 0.012” oil feed hole in the cam face. The added oiling capacity creates a boundary layer that protects both the lifter and cam lobe from excessive wear.

    Have you ever been to the races and heard how nasty the cams sound? COMP Cams has developed the Thumpr series of cams that give you every day drivability but have that nasty race engine sound. Pick the cam that fits your application, add a set of COMP Cam hydraulic lifters and you will be the talk of the town. 

    Thumpr Camshafts are a new series of retro-fit hydraulic roller and hydraulic flat tappet cams designed for use in a variety of small and big block V8s. The aggressive exhaust note of a Thumpr cam comes from a combination of early exhaust valve opening, long exhaust duration and a generous amount of intake and exhaust overlap - maximizing the rough-idling characteristics of the cams without negatively impacting power or streetability.

    These camshaft / lifter kits are perfect for use with SBC 377 to 390 CID with Air Flow Research 190 to 210 heads. Max Power 6200 rpm, Peak torque 3600. This cam is designed for engines using 3.750" stroke with the AFR Heads and their high Intake the Exhaust flow ratio. This cam maximizes the power potential of these heads by taking advantage of the RAM Effect caused by piston velocity at low rpm. Increase header size of 1.750" is highly suggested to take full advantage of the power band of this camshaft.  Adding 1.6 ratio rocker will increase rpm to 6400. We recommend a 3000 stall, an 850CFM carb, and a minimum of 10:1 compression.
