Electronic ignition upgrade.

Best to detail your engine and car whenever asking an engine question. I had to scroll down to post #46 to learn. Easiest is the 8-pin GM HEI module (1985-95) with their coil and cable which connects the two. Many posts and TrailBeast here use to sell as a kit for those who don't go to salvage yards. The Mopar e-distributor can trigger it. Losing the ballast is one advantage. Mopar ECU's tend to fail and replacements today are suspect.

For those with a points distributor, the Ningbo "ready-to-run" HEI distributor is simplest, paired with an e-core coil. Check Steve White Performance on ebay. A kit should be <$100, but only avail for SB & BB, not slant.
