Throwing my hands up on this ignition!

People will hate me for this, but...
Ditch the MSD. Get a nice older chrome box, and new coil. And throw a spare ballast in your glove box.

No hate from me. I cannot STAND anything MSD. The stock ignition can be much better through distributor mods and upgraded modules.

...yet, so far the one person who disagreed with you is the one person who could benefit from your advice. lol
