88 2.8 to 350 swap fuel pressure?
have a 88 camaro with a 2.8 that I'm putting in a carbbed 350 and need to know the fuel presure that the is needed for the carb.
I want to keep the stock fuel pump in the tank and want to add a fuel pressure regulator and ont what what psi to get

Use a return-style regulator like a Mallory 4309 set at 4-6 psi.

A return style allows a constant flow of fuel through the pump. It regulates pressure by restricting return flow to the tank to maintain the set outlet pressure to the carb.
A dead-head style reg (the typical $20-$40 type) controls pressure by stopping outlet flow to the carb.
The in-tank pump needs flow to keep it cool, so using a dead-head reg will eventually burn out your pump.
