Maybe less work than you think. I wouldn't bother undoing your dizzy mods. You say the problem happens with the car just idling. If you wired up the MSD with a connector plug, you could make up a few jumpers to temporarily hook into the stock CDI unit. Set static timing at something reasonable (I don't know, maybe 20 BTDC) and see if your problem persists. Maybe it's this rotor phasing thing, or maybe it's a wiring problem with MSD, or maybe the MSD unit itself is wonky.
