And if that HEI was popping like it should, you probably would feel it in your arm as well if it was touching anything metal.
Sounds like your HEI isn't putting out the power. Check the wiring going to the distributor cap to make sure they're seated. Just grabbing straws here, if the cap has been changed a lot or messed with a lot, those plugs into the bottom of the distributor cap get cracked/broken where the clips don't always survive and the plug can work its way loose. It might LOOK hooked up, but may not be.
Also, take the cap off and check condition of the coil button to the rotor. I've seen those literally disintegrated before. Plust the general condition of the cap/rotor.
As pagrunt says, it could be the module. Those things hum along happily until they simply just quit. VERY often HEI distributors simply quit without warning due to the module. Although rare to have issues like that, it happens. Ensure if you do find out that's what it is, that you put dielectric grease on the bottom mating side to the plate. Need a good heat sink for it.
