My question is, does it worth swapping the 4bbl intake in place of the 2bbl and using an adapter for my tbi?. This is discussed to death in the mustang world, and done all the time. You will need to add an O2 bung to the Y-pipe, and a wire from the fuel pump relay to the fuel. i have the throttle body, and fuel pump. Product Description. I have an 1983 chevy 350 carb motor in the crawler now so the gist what can i or should i rob off this. Also, most people run a dead-head fuel system with no return line with their carburetors. A stock harness has a ton of circuits you won't need for a conversion. This is a new GM fuel pump kit and will only fit 82-92 carbureted and TBI cars. so take off the intake.
