Ok so i got this TPI setup and it comes with basically everything except the wire harness. Now i dont know much anything about ecm's, and the different systems ive been reading about on here. What would i need to do to get this TPI setup to work on the 350 im building, considering i have the 305 TBI right now? Will the TBI harness work, or can it be repined maybe someone could explain that one to me cause im not sure what the exactly means either...Anything helpful would be nice.

Thanks alot
John

 

The main page has a "TBI to TPI" swap.

Search function is also a valuable tool.

 

What year is your car and what year and car did you get the TPI set up off of?

 

My car is a 91, and the setup said it originally came off a mid 80s camaro when i purchased, but than the guy said he took it off a Small Block Grand National. The setup came with 30lb injectors.
