91 TBI 350 into my 86 Iroc
I have a chance to get my hands on a 350 out of a 91 pickup... 4 bol main tbi....I was wondering what I would need to swap that engine into my 86 Iroc TPI 305, 700r4, and to swap the TPI onto that engine

A set of gaskets. Some different fuel injectors, and a 350 chip for the computer. I think you would probably do best to try to use the 305 heads, as opposed to the 350 tbi stuff, or at least get some different heads.

The 305 heads would work nicely on that 350 with its dished pistons.
You wouldn't "need" 350 injectors or chip, adjustable fuel pressure regulator would do most of it until you got into more performance mods on the 350. 350 knock sensor & module are typically recommended, though.
