Putting an 85 350 TPI in my 89 Iroc that had a 305 TBI in it. I just obtained a 88 350 TPI ECM and computer last night off of a member of this forum, Now I just need harness, TPI fuel pump and lines, rubber air filter intake boot, and maybe a mass air flow setup since I'm going from an 85 to a 88 setup? I need to do a little more research but for now just a engine harness since the one given to me with engine might be off an 85 and not compatable with the 88 ECM.

Thanks, if you have any of these parts please let me know prices. -Gary

Specificly an 86-88 harness. I don't believe anything else will work. Thanks.

Harness no longer needed. Going with speed density.
