Chevy V8 Hei dist. starts and runs fine at idle at higher rpm starts minimal back firing? When on gas hard and let off pedal big back fire? Could problem be bad stator/igniton part that fires off of star...

Yes...timing. Adjust the distributor...back it off a little and set the timing....also check your carb setting for rich/lean mix....air mix will cause this also.

What have you done to the system to cause this or were you trying to adjust something?

93 chev 1500 won,t start

typical fuel pump issue.. Usually around $600 to have it done. The tech would check for pressure and then test the ground and the power souce for a voltage drop. If all this is not done to verify you need a 600 dollar pmp you cold be just throwing parts at it as you go.
