How do you Convert HEI to Mopar

I did many years ago. Took one of the old Corvette breakerless distributors with a tach drive and shortened it, had a machinist tang the shaft end and redo the shortened casting for a bushing. It sat into the bottom of a collar cut off the bottom of a junk Mopar dist machined to fit the GM distributor.

This was a Chev dist redone for a SB Mopar, as they both rotate CW

This was in the early seventies, and was used to trigger a Mopar ECU. This was before I knew about rotor phasing and it did not run well. I'm sure if I'd played with it some I'd have found the trouble. This was also before some of us realized you could adapt the HEI module.

That is kind of what I was thinking when I heard about HEI conversion. I had always heard and still hear that the original Chrysler electronic ignition was one of the best . I could really only assume that the advantage of the HEI was the size of the cap and the simple hook up . You learn something new every day.
