    • Adds up to 30 HP over stock rockers
    • Excellent replacement for stock or sportsman engines
    • Eliminates noise & slop associated with worn or high mileage rockers

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
    (Part #91515001)
    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!
