yes the HEI will clean up your wiring + you get to throw the ballast away for good if the module goes up you can just pick anouther one up at a parts store really cheap and the mod will only cost you about $30 the only other thing you will need becides the module is a few butt connectors (or I like to solder and heat shrink them) also you could really benifeit from going with an msd blaster coil. I did the mod a few years ago 4? somthing like that and I'v never had a problem with it yet

You only get to throw the ballast away if you go the full HEI with the coil in the cap. If you use one of the distributors with the HEI module hung on the side and a conventional coil you still need the ballast recommended by the coil manufacturer. If you purchase a coil that does not need an external ballast you you could use it with a mopar system without the ballast too.

Mopar modules, pickups and such are just as easily picked up at the local parts store and are just as cheap as the HEI parts. Other than eliminating a couple of wires there is no advantage to the HEI system over a mopar electronic system.
