    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

    I also have an ‘88, mine is tbi. Will this work with my existing tbi setup? Will an adapter plate be needed?

    Asked by: Phototrekkin
    An adapter is required to retain the TBI , but be advised this will not work on a 305

    I have an 88 tbi 350 I'm planning on running this kit on, what would be a good sized carburetor to run?

    Asked by: Brandon95
    A 600cfm carb would be good to run on this setup.
