Backfiring

I was out today driving my 73 and it was running great with all its usual power and it was idling smoothly, but as I was driving along a flat street at 30 in second gear with a constant throttle, it backfired. After driving a couple more miles, it did the same thing. The engine was warmed up. It was running perfectly except for the backfiring. The car is a very original low mileage car with the original MFI.
