I knew I forgot some info ... the snap was heard with the engine not running, ignition on. Because the exhaust is so loud, I can't hear what the ignition system is doing at idle or hear any snaps. I wish I had turned out the lights last night and looked for a lightining storm in my engine bay! Also, it seems like the engine hesitates at low to moderate engine speeds, however when I go full throttle, it seems OK. I say seems because when I back off at 5000 RPM, I get a barage of backfires. Cool for the racetrack, but not the street. That's why I've always concentrated on the carbs, but since they're clean, something else is out of whack.
Warren, My intentions have always been to move the fuel pump to that location! I have a larger capacity fuel pump from another car that I'll give a try. The coil I replaced the original with was another original from another problem solving exercise. I'll check both for resistance.
Superman, Your diagnosis sounds good to me. I'll replace the cap and rotor and try to make sure the plug wires are not resting against any metal surfaces.
Unfortunately, I have to go to work now, so I'll check in with you guys later!
