    im sure someone could answer this for you but,

    this is mostly a ls based truck forum, i know alot of ppl over at fullsizechevy.com could answer you in minutes might try over there.

    or you could just do a ls swap then put a ls6 cam in there lol

    an Edelbrock performer or preformer rpm package would do wonders. You would also have to get a new chip burned for it though.

    You're going to have to swap other parts of the valvetrain. No matter what.
