Well, I gave up on the Mallory. I put in a new LED unit and still does not fire. Lined up the arrow on the rotor to the eye and it's dead on #1. Does anyone know for sure if these are compatible with the mopar electronic boxes? I thought about going to an msd or mallory but, I don't want to waste money on it if it's no better than what I got. Currently I'm running the mopar performance without the vac advance. I pulled the distributor apart and locked the vac advance plate in place and completely removed the vac advance stuff to free up a little space. I'm running about 12* initial and goes straight to 35* total at around 2000 rpm. Think I should just leave everything alone? I don't have any issues with the unit that is in there. Just looking to upgrade.
