Re: Swap question
That was my concern... with the VIN reading TBI, and the motor being TPI... Or is it that the smog tech would see f-body and available motors are v6, TBI, TPI (must have one)

Re: Swap question
imadude .... if you had a LO-3 how come you didn't just re-pin the original harness to run TPI?

Re: Swap question
My old harness was pretty messed up... cut in lots of places and "creatively rewired" (due to who ever owned the car before me)... So I got a new harness with the TPI swap parts, but it was from a 90 Formula... But another harness from a 91Z is coming this week.

Re: Swap question
The 90 to 91 difference was the big one, but there were some differences between the Firebird/Camaro (the big one being the battery location). The Firebird one would work, but the Camaro one will go in quicker and easier
