tbi to carb
i currently have a 350 runnin with stock 305 tbi manifold and heads, i was thinkin of replacin that with a ported set of heads and carb but dont wanna change the fuel pump, i was just wanderin if i just put in a in-line fuel pressure regulator what the pressure would need to be for a carb or does it just depend on the type and size of the carb

You need to run a return-style regulator set to 4-6 psi.
Don't use a dead-head type regulator. Your pump will hate you if you do.

By dead head he means no return. Like a river flowing up to a dam with a small hole in it. Anything after the hole finds it's way to the motor. The dam being the regulator. Tends to put more stress on the fuel pump seeing as how it was made to be used with a return style.
