Points or HEI distributor? HEI wants a full 12v while points coil wants ~6V obtained via a resistor wire/block. HEI + resistor = problems. If you have HEI, possible the wire you are using is the OEM resistor wire for the original points setup.

Make sure the ground strap from the engine to cab is in place. They often get lost/left disconnected during valve cover changes or engine swaps. Traditional place is from cab to passenger side valve cover bolt.
