305 to 383
Im getting ready to put a 383 in my 91 rs. Im using a 70s 4bolt main block, 90s heads, and an internally balanced crank. Ive been looking around the posts but i havnt found much about what im going to need to change along with the engine. Im trying to do this cheap and im keeping the tbi system. Any help would be greatly apreciated.

Re: 305 to 383
did you mean TBI (Throttle Body Injection), or TPI (Tuned Port Injection)? I would think the 91 RS would be TPI... If that's the case, I can give you some info, because I just finished a 305TPI to 400SBC Carb'd swap
