1957 Chevy 283 with all new ignition components backfired thru exhaust prior to change and also after. What could be the cause? Replaced plugs, rotor, cap, condenser, plug wires...

Engine ran great on an 8 mile drive then started backfiring and missing on the way back home after being shut off for about 40 minutes.
It is backfiring through the exhaust, I've replaced all ignition components and checked timing several times in search of the problem.
