Any Pertronix experts here?

Totally going crazy with this car, I had a friend that is very knowable about cars, engine, wiring of cars, he came over, rechecked the timing, got number 1 up to top dead center, started with number 1 plug wire on cap, found I was 1 position off on the cap.

Tried to start, nothing, would not even try to start, my friend pulls out his handy danie spark plug tester light, hook up to number spark plug, crank have yellow/red spark, he states we should have a blue/white spark, feels bad coil, check to see what voltage is going to the coil while cranking drops to just under 12 volt [11.7] . I removed the ballast resister so full 12 volts to the coil. None Mopar ignition. Have all new spark plug wires.

I am running a new Pertronix 60115 dist. per them need a .6 ohm coil so I order 45111 which is a tower type coil, 45000 volts , get all installed, retest with spark plug tester light while cranking, still no blue/white spark, car no start.

Really running out of items to check, replace Grrrrrrrrrrrrrr!.
