I have a 1972 440 with a mopar transistorized ignition. The distributor looks like one from a car that has points. It has a vacuum advance which doesn't seem to do much when you run a vacuum line to it. Is it normal to not have a vacuum advance with a mopar electronic ignition? Or does it need to have different distributor to get it to work right?
There does seem to be a little hesitation and some and minor backfireing. This could be carb related or timming but was wondering why no vacuum advance. Is it correct to have it that way?
