1988 trans am problems

i own(ed) a 1988 Pontiac Trans am gta 5.7L TPI. since i was having p0roblems with the tpi, i decided to convert to carb. here is a list of new replacement parts:

edelbrock intake(#2104) and carb (1406)
msd hei distributor (#8362)
jegs fuel pressure reg (#15911)

the problem i am having is flooding - the carb is over flowing with gas. i am heading into my third carb because my mechanic said this should not be happening. please help me!!!!!!!

Sounds like the FP is too high, what is it ? Shouldn't be over about 6-7 psi max.

after discussing my problem with edelbrock techs, it appears that my fp exceeds the handling fuel psi of my fuel pressure regulators. looks like i will be pulling the fp and installing an external (aeromotive or holley) fp.
