gmc,
i'm going to start on my 302 soon and i'm thinking that i will use a water heated clifford intake with a edelbrock 500 4 barrel carb and maybe a nixon repro header. also will use a H.E.I. ignition. i'm sticking to the original cam as this is a N.O.S. short block that i'm using. you may want to go with a little hotter cam, the guys here on the board can help you with the type [lift duration etc]. you might be interested in the inliners international web site [ and joining the club too] lots of helpful people just like here!!!
