305 to 350 (can't find what I'm looking for)
1st off I have a 85 IROC with the 305 TPI and I'm going to be swapping it for 350. What I need to know is if I change the injectors and ecu can I use my TPI set up on the 350?
Thanks

You can use the TPI from the 305 plus other external parts plus you will need the following.
Knock sensor
22# fuel injecters
New chip for the computer (not a new ECU)

The '85 TPI ECM wasn't their best effort. You might be better off getting a later MAF ECM while you're at it.

More hardware to change than if you just stick with MAF.

The TPI setup itself is exactly the same on 305 and 350 engines.
