305 tpi in a car that had a 350
Hi guys. I’m putting a 305 tpi in a 88 camaro that originally had a 350 tpi. I have all the front of the motor brackets from the 350 and all of the accessories-alternator ac smog power steering, but will the wiring harness be the same? Will there be any modification needed?

If everything is still there then yes, a tpi 305 can go where a tpi 350 was. Injectors should be changed to the 19lb 305 injectors and the ecm tune would need to be changed to a 305 tune. (Swap chips in the ecm)
there's a couple things that were 305 specific as I vaguely recall, knock sensor was different, icm maybe was different. Regardless the wiring is all the same.
