Pro comp sells lots of stuff (mostly made in China). Post a photo of the distributor you are talking about. Search "ready-to-run HEI distributor" here (and ebay). Many posts w/ experience if that is the distributor you refer to. I don't know how an HEI module would help if an MSD box will drive your coil.

If "stock dizzy" means an electronic one (~1972+), that is as good at driving an MSD box and probably more reliable. A points distributor is not so good. You didn't tell us the year of your car & engine.

If you want to use the HEI to trigger MSD, connect white MSD trigger wire to black HEI wire that would have went to coil negative. Red HEI goes to 12V ignition, that comes from IGN1,IGN2 connecter together by bypassing ballast. Ignition coil hooks to MSD.

Follow MSD instructions, similar to using pertronix, or Mallory Unilite.
