RE: 390 Backfires through exhaust on deceleration

I used to have the same problem.....would clean the points and it would go away for a while. Changed to Pertronix and no more trouble. Since you already did this, I wouild check your plugs and wires. Wires dont' last that long (2 years max unless you get high quality ones). Go for 8 mm ones. How's the dist cap and rotor?

This thread, so far...
