...........Doesn't sound like he has a HEI compatible coil or do u not need that?.....or like others say the pick up in the dist........if u have the vac line on the dist unplug it and see what happens.........kim.........
Before I tore mine down for paint I was simply running the factory Mopar coil. HEI does not seem to be fussy on coils. You CAN get better performance by using an optimal coil with them.
