Any thaughts, experiences, advise would be appreciated.

Greetings Randy!
Did the engine backfire with the original distributor? Or is this a condition that just developed after you installed the new distributor? If your engine is backfiring through the carb on acceleration, it could be an indication of the engine not getting enough gas, in other words a lean mixture. It can also be an indication of late ignition timing. It's been so many years since I tuned up my old 305 (which I no longer have) that I've forgotten the exact specs on ignition timing, but a good place to start is 6 degrees before top dead center. The vacuum advance should be disconnected and the vacuum source plugged or capped off when setting the timing. I could be of more help if I were there and could observe the engine's behavior up close and personal. Hope this helps you.
