    OK... so i am in the process of choosing a new cam...
    anyone have dyno software i can "borrow"

    Can someone give me a run through of how to install a cam... i know basically how but the adjusting the lash is still a mystery to me...

    Difference between Hydriolic, mechanical and roller?
    I know about roller lifters do they require special cams?
    And how do i know if i have 1.5 1.6 or 1.7 rocker arms?
    It's a BBC 454 if that helps?

    Adjusting the lash will depend on what kind of cam you have. Instructions will come with the cam. Read it carefully.

    The difference between hydraulic, mechanical, (solid) and roller cams (which also come in hydraulic and solid) are the kinds of lifters you use. The use depends on your application. Yes, a roller cam is a special cam. The lobes on a roller cam are much steeper than a flat-tappet. Most likely you're going to use a hydraulic flat tappet cam in a truck application, unless your engine had a roller cam from the factory. Solid lifter cams require a lot more maintenence than hydraulics and are usually for high rpm/racing.

    I believe a stock BBC has 1.7:1 rockers.
