Measure the DC Volts between Coil + and - terminals with the key in the 'ON' position.
That just shows a small voltage difference between ground and the negative of the coil.

Coil voltage in the key run position should be at least 6-8 volts. Did you try to replace ballast? You can check continuity of ballast resistor with an ohm meter. Just disconnect two wires and check for resistance across the 2 lugs, should be about 1 ohm.
If it is running like crap it could be a lot of things from problems in the ignition system to a piece of crap in one of or multiple carbs. Since these do not have an ODB port, you are going to have to go "old school" and do some testing and more than likely a process of elimination. Start at the easiest and move to the harder items and you will most likely find it or you may not and it will seem to fix itself. Welcome to old car ownership...
That must be with the original ECU still connected?Ok, will do!
00.00V between +/- poles on coil with KEY in RUN.

I was gonna ask you if it was MSD ign but I take it you have the Mopar ign. I don't know what you have apart now but I was going say to unhook the coil + wire and then check the volts on it with key on. It should read battery volts like that since it would be open circuit. And if it was MSD I could understand the near 0 volts to the coil + with key on since the coil in MSD is not hooked to a 12 volt run wire through a ballast like a stock ign is as both coil wires go to MSD box in that setup and can get up to 300 volts when the capacitor fires the coil in MSD but it may be near 0 with just key on with MSD. Anyway it looks like you have her tore apart. Good luck with it , Ron
