Mike,
Check header pipes and flanges for cracks or air leaks that will do it.
cheers,
Bryan

I agree. Leaky exhaust headers are a common cause of this problem.

Exhaust leak will do it every time!

Ultra copper on the header gaskets helps a lot.

You can get a backfire from a loose plug wire, or any other cause of weak spark to one plug. Unburnt fuel ignites in the pipe on the side with the spark problem.

Be sure to check your distributor. I just had an MSD break a roll pin on the bushing above the timing gear. My car was also just backfiring on the right side.
