Re: Engine Backfired blewout muffler & resonator

I had the same missing and backfiring problem with my 1955 Clipper Super. One backfire blew out the muffler. The problem was the distributor terminal insulator was cracked and allowed the terminal to ground against the distributor body causing the misses and backfires. I had been working on the distributor and must have over tightened the terminal nut which cracked the insulator. I replaced the insulator block and all was well again. It had the Autolite distributor, maybe the Delco is similar. Here are photos of the culprit. Hope your problem is as minor as mine was. Good luck.
