I have a 91 Camaro 305 TBI and want to know if a TPI intake off same year car with 305 also would work, providing I swap wiring harnesses, computer chip, and fuel pump??

Yea it will work but if you do all of that and leave the stock LO3 heads and cam on there you will only gain about 10 or 15hp.

Well you would be right near what the 305 TPI makes. That would be anywhere from 190 to 225. You are going to need a full ehxaust and chip burning as well. I would use the TPI heads but would not use the TPI cam. Go with something bigger.
