Double check all the rubber suction lines between the tank(s) and the fuel pump. A small air leak in one can cause intermittent running issues. If they are original, they are end of life anyway. An accel pump will work even if the fuel level in the carb is low.

Might double check the power to the HEI. Corrosion or a size mis-match between the power wire end and dizzy terminal can cause an problem. I wouldn't trust the newer China stuff to have the proper terminal size or coating to resist corrosion.
