TBI to TPI SWAP *** HELP***
TBI to TPI SWAP *** HELP***
Hey,
I am looking to do a TPI swap into my 1990 c1500 pickup. I have a 350, and have a Tuned Port that i am about to buy. I want to know all the steps that need to be taken in order to make the swap work (keep it brief). I would like to know what I am getting myself into before I start.
Many THanks!

This isn't an "Engine Swap" topic. Perhaps they'll be willing to help you in the TPI forum.
