I think the confusion is that we don't know what dizzy you have. If the 1975 car in your sig, then it already had electronic dizzy, so what is this "upgrade"?).
The car was a /6 car. The drivetrain was swapped out for something a bit older IDK what year but I do know it was a points 318. I "upgraded" to a generic mopar electronic dizzy from a guy on CL.
Since rewiring to a two post BR and the proper schematic I have not had an issue. Its been around 800 miles so I m crossing my fingers. She seems cured.
