thanx in advance

check out this thread. Tpi to carb swap.

If you use the intank pump, and a adjustable fuel pressure regulator, you should be ok. The stock TBI pump puts out about 15 psi and a carb only requires 5 to 7 psi. The regulator has to be a return style.

I swapped from a 305 TBI to a 350 TPI motor. No I have converted over to carb. Good luck and welcome to the board.

Here is the adjustable fuel pressure regulator (afpr) I used.Mallory AFPR

Yeah I swapped from a 305 TBI to 350 carb and used that unit as well. Works good.
