Putting GM stuff on a Mopar. I see plenty of posts with people trying to figure out HEI installations. MSD is as simple as you can get! Two power wires, two pick up wires and two for the coil. And it will outperform any ignition mentioned here. The MSD6A fires six times for every one of a conventional ignition(hence the name 6A). Better performance faster starts it's a no brainer.
