With what you have under your sig I suggest an electric pump drawing from a sump, 1/2" feed line with a bypass regulator and a 3/8" return line. Sounds race oriented, but it will keep you from having fuel problems down the road.
I would go Electric, I'm running a Holley blue pump and no complaints here. Also like ranchero said, do it right once and you wont have to mess with it again.

I'm gonna bring this one back from the dead after reading through 8 plus pages of reading results from searches...
My combo is a 87 5.0, stroked out to a 331. It has forged pistons, rods, crank, and compression ratio sits right at 10.1-1. Heads are AFR 185's, Air Gap intake, carb is still yet to be desided. It has early style timing cover, so a mechanical fuel pump is needed.
The car is street car, but will see ALOT of drag duty.
Im looking for a mechanical pump that will feed it. People say get stock pumps that flow 30 gph are fine...but the aftermarket pumps flow 80-130 gph..Whats needed for a 420 hp car?
