I had posted a topic under fuel delivery but didn't get a whole lot of answeres there.
Setup is an l28 w/ triple webers, holley red fuel pump, cheap regulator from the auto parts store.
If I mash the pedal it will cut out until I let off. I can go full throttle if I'm nice to it and and gradually step on it.

In short it says use a fuel pump with more volume, not pressure, don't run a Vacuum hose into the manifold (which I am) but I've seen people using the same pumps and not have theseen issues.
I bumped the psi from 4psi to about 6psi because it seemed to help a bit.
