Intake, camshaft, exhaust, y-pipe, cylinder heads, all sensors, ECM, engine wiring harness.

You can keep your short block if you ditch the peanut cam.

Allright, this may be a dumb question, but what is B-O-P?

Add fuel pump to that list. Probably easiest (best advised) to just drop the tank in the receptor car and put in a new TPI pump.

Did you read the tech article on this website that describes the procedure? Its outdated now but it will get you started. Not to mention the hundreds of other threads on this topic should help you out.

Good luck and get ready to enjoy all the new power and torque the TPI swap will bring you!
