Need help understanding Mopar ignition…no spark

I have to ask the obvious question?

Is your timing set correctly? Did you set top dead center? Are you 180 degrees out?

Timing is good. it fired up fine when I moved it from the garage and then wouldn’t restart. I did check TDC though. Since then I did the GM HEI conversion so it’s not a timing issue but could be a distributor issue. right now I need it generate spark at the coil before I worry about distribution….

I measured the distributor inductive coil output while cranking and was getting an intermittent reading (As it was spinning) of 1 to 2.5 volts which seems right? The gap seemed right too.
