Distributor Issues/ mysteries

On a sbc 350 we have been having an ignition issue where it has been misfiring. We have tried to switch the hei out for a different one which did not take care of the mis. Then we switched to a point type distributor and the mis went away. We have swapped out the cap, rotor, ignition module, plug wires, and coil out of the hei distributor and it still misses. Can anyone think of something that I might be overlooking that can cause this issue

I bet your running this in a car that didnt have HEI on it from the factory.

If so theres not 12V at the coil wire, there is a resistor in the line somewhere.

run a switched FULL 12v line to the hei and I bet your problem will go away.

thanks for the help but we found a little faulty ground. It wasn't enough to stop the starter from working but enough to mess with the hei just a bit
