Beginning to think my problem is in my wiring, as when it ran fine before was before I wrapped and bundled to make it look pretty, and the battery is on the passenger firewall now. So I have a chevy 1 wire alternator wire running across there as well as all the MSD and other stuff bundled into about a 1" group.
Perhaps the coil fix was a part of it, but this might be another big part as I have read that alternator is the worst for interferance. That, the plug wires in parallel on the 5 &7 and the dizzy and coil and alt wire in that bundle, even if they're not next to each other.
So I'll go through the valve adjustments looking for any gremlins and then tear apart my sweet wiring job. If I go with that other dizzy I'll need to pull all the MSD wiring out anyway. so I'll get it back to ugly and seperate and see what happens.
Edit: and also adjust the idle air/fuel mix
Might also note the alternator wire is in that bundle as is the power main for the car, and I have 3 electric fans on it.
