305 vs 350 TPI - DIFFERENCES? Alrighty, i have a quick one for you all. is there any physical difference between the 305 and 350 TPI top ends? are the TB's, plenum, runners, base, ECM, etc the same? i know the injector sizes and chip are different. are the units physically interchangable? would a 305 TPI top end bolt dirctly to a 350 with an injector/chip change?

Stealth Ram, AFR's, and a healthy cam (and a good tune) and you'll be just fine.

I agree with Demonspeed, junk the TPI, I had designs on a 350EFI setup in my old thirdgen and the TPI system is too limiting.
