If that's the reason for the problems, maybe a dizzy from a P6, SD1 or
9.35:1 Range Rover would suit better? There's also plenty of speed shops
that can re-curve them. Otherwise, maybe talk to Mallory about their
distributors. You could also consider a MegaSpark or other programmable
electronic ignition system.

I'll hazard a guess that an regular 8mm lead from coil to cap might fit
OK, but the MSD website shows a bunch of lead options. I'm sure they'll
have a std dizzy to coil lead.

O2 sounds like a fair guess, but check the rest of the system too. Eg,
check the temp sensor, so it's not stuck in warm-up enrichment mode and
so on.
