    It says up to 575 lift flat tappet camshaft. What size cam would be best for a .30 over 350 ? It will be used for a oval dirt track race engine.

    Asked by: Dewayne333
    Something near .525" lift in the " Comp Cams Oval Track " series will give you constant power to 6500 rpm. We would need to know a little more about the engine and vehicle setup for a more exact answer 1.800.345.4545
