2.8L to a 5.7 LS1

I have an 89 camaro with at the moment a 2.8L v6 with an auto trans. I just bought a LT1 for it and i am wondering what i need to change and if there is a kit for swapping tbi for a tpi wiring harness??

Re: 2.8L to a 5.7 LS1

are you talking about LS1 or LT1? heading says one, post says another... and why are you looking for a TBI or TPI harness?? going 2.8 to LS or even LT for that matter, you would need the engine harness meant for LS or LT
