454 Southwind Popping back at carburetor solved-- revised

Anyone with the 454 and HEI ignition (OEM) should always check the distributor cap when issues arise. You need to turn it over and with good lighting look at the plastic near all 8 of the plug wire contacts on the inside of the cap. They were notorious for cracking, then arcing between each other. If you have a bad cap, replace it with a higher quality aftermarket model.

The 454 with the HEI ignition and quadrajet was a great set up when everything is working.
