Thanks for all the good info input guys. Playing around with some mopar HEI Conversions here. Helps to understand things better.
Yes the HEI with the full 12 volt E Core coils do put out the hotter spark. Setting my plug gaps at the .040 ths range, as have heard you don't need the wider gaps as long as there is fuel there to burn. Wider gaps they were using in the lean burn smog area.
Fun to experiment with things.

95 Ford F150 has a nice simple 2 prong + - e core coil that is easy to wire in, runs cool on the full 12 volts, and runs correctly with the HEI setup.

Grabbed some parts from the local You-Pull-It yard to experiment with.
