Changing tbi 305 to tbi 350 92 camaro rs
 

Im thinking of changing my 92 rs 305 tbi to a 350 tbi what else absoulutly has to be changed could it be ran fine with just the swap or would I have.to change computer
and about how much hp would I gain

idk about the computer but hp would be about from 10 to like 50 hp gain not a hole lot

I'm pretty sure you have to change the computer as well. I was thinking of putting the crossfire onto the 350 that I have for and then found out just how much it would be to get new injectors and a computer.

For one you don't have to change the ECM (computer) but you will require a new Prom (chip) with updated for a 350. Also needed 65# FI , 350 knock sensor.
