I'm about out of ideas except maybe try a few things

1...Post a photo? of the module mount, make sure it is flat, mounted and heat sinked

2...Just because the pickup polarity ran much better one way, does not mean you don't have rotor phasing problems, which I'd suspect

3....You should be able to disable the charging system by yanking off one field wire either at VR or alternator, and the car should run fine.

4....How long are the dist. pickup wires and are they twisted? Are the pickup wires run away from other high current or high voltage wiring, and cross at close to a 90 angle?

So far as a coil, I just used the stock Mopar coil on mine, ran fine.

2. I tried reversing wires, the car would only run with W hooked to orange. Drastic difference. Seems unlikely that I would have rotor phasing problems with both my chinese reman distributor, and my custom-curved rebuilt OEM distributor. They both did the exact same thing. Intermittent spark and backfiring at higher rpm. Regardless of timing setting, swinging all the way from 0btdc to 15. Car would respond as you expect to the timing changes, but they did nothing to change the intermittent run condition.

3. I will try this, but I don't understand how it would effect the ignition system. Tested the ignition control module feed wire and the coil feed wire, both were getting full voltage at idle and higher rpms. No dips or surges.

4. Pickup wires are as short as i could make them and reach. Picture posted. I had both distributors hooked up to the module this way, maybe thats my issue? Can't twist around the portion where the butt connectors are. There are no other wires around in the area, its the back right corner of the distributor behind the kickdown bracket. Closest thing is the wiring harness on the firewall.

Do you have another module to try? I have a tester for them if needed also. Stupid question can you bring it back to the oem mopar ecu just to give a starting point again?

I never had a mopar ecu, converted from points. I really wanted something 100% solid state, no ballast resistor. I tested the module yesterday morning 5x and it passed every time.
