HEI old school distributor

The way to do that is to use a Mopar breakerless dist as used in the early 70's and later, and use it to fire an HEI module. You can use the stock coil or not, and eliminate the ballast resistor. There are hundreds of posts on this subject, a few guys have even gutted a Mopar box and installed a GM module inside

A nice diagram done by a member here for a 4 pin. Pay attention to the pickup coil wiring polarity. You must break/ file a locator "tit" off the bottom of the module, mount it "flat" on an aluminum heat sink, and make sure the mounting holes are GROUNDED
