Hey all!
First post here. I recently bought my dream car, 1976 Pontiac Firebird Trans Am with a 455 engine. The prior owner kept it mainly at stock and appears to have only added a Fitech fuel injection system and duel exhaust. I am wanting to upgrade the engine but see a lot of posts stating that the engine needs to be rebuilt first before upgrades are added or it wouldnt be able to handle the upgrades. Is this actually true? Yes, the engine is old but it appears to be in great shape. Is it more of a better safe than sorry situation?
Thanks!
