    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!
