So far I have rebuilt the fuel pump, replaced cell foam, filter, installed MSD box, new coil, cap, and wires. I put in new float valves, reset float levels, checked and re-checked timing. Adjusted and re-adjusted carbs. Changed pertronix, distributor with only minor results. CHecked alternator voltage, upped fuel pressure. Added fuel, etc.
This problem does not occur until the engine is under load. No break up in the garage and will rev to 7k.
I am at a loss. This problem seems heat related. I had a thought last night that I am wondering if I get a voltage loss through the master switch since the MSD box is connected there.
