coil without ballst resistor?

I did this just as an experiment. The GM HEI does "manage" dwell and current and that might be what makes the difference. I cannot of course guarantee this as this WAS just one car, one coil. But I also had a GM HEI module on a Toyota 22R engine I'd installed in a dozer. Same deal, the coil was there --likely stock Toyota--so I ran with it. The old girl is gone now.
