Hei conversion troubleshooting

The overcharging issue is fully resolved. I ran a ground strap directly from the new VR to the alternator. It is now showing steady 14-14.5 v in all modes.

Unfortunately, the car is still running like complete ****. Same problem I had originally. I tested the ignition module, passed 4 tests in a row. I have hang tested a brand new coil and that did nothing. The weird thing is sometimes the car decides to run right, revs up cleanly but won't do it every time. The condition is very intermittent which makes me think electrical. When I first put the new distributor in, it ran good that night but when i fired it up the next morning back to normal. No major temp variations, and it does it whether the engine is cold or warmed up. I am stumped.
