Henry,
The coil is from Pertronix at the same time I purchased the conversion parts from them. The plug wires are from them also, and while they are supposed to be ok for HEI, they could be the problem, as I bought ones that look like stock, so they are not very large.
I checked the supply wire last night and I have 12.3 volts with the ignition switch on.
I'll try looking after dark tonight for leaks.
