I’m thinking of building a twin turbo firebird. I have a 1970 firebird that I was going to build a fairly radical NA engine for. The plan was to have a very fast car to drive on the street. But now I’ve been seeing a lot of turbo cars be faster and more street friendly.
I have an aluminum IAII block, 4.5 steel crank, Oliver 6.8 rods and 4.35 pistons with a 27 cc dish. The block is already bored for the pistons. For heads I have a set of wide port high ports or a set of 380 high ports. Both with 56 cc chambers. KRE told me they can redo the chamber up to 80 cc’s.
I’ve built many na Pontiacs, but never a turbo. Where should I start? I know headers are a problem. I can change most of the above parts if I need to.
