I'm not sure exactly when my car was built. But I do know the engine isn't original. Its YD code 400, which wasn't ever offered in a Firebird.

I've already installed the edlebrock intake and it runs like a champ.

The question is whether the original intake that came off my YD engine (and is now sitting on a shelf in my garage) is worth repairing, to the tune of several hundred $$$.
