Ok gathering parts for my camaro swap, going to go with Tpi. My 350 is a 88 Tbi from a chevy truck, i was planning on repinning the wiring harness, but will i be able to modify my 2.8 harness to work? Second i am going to use the 88 swirl port heads as Thats what i got to work with, is their any difference between Tbi heads and Tpi heads, other than the intake is bigger on the Tpi and the exhaust is bigger on the Tbi. Thanks for reading my thred and i plan to keep ya all up dated!
