On the subject of coils
- twin coils wouldn't help much because the high voltage would be the same (same dwell from the dizzy, same output)
- dual points help by getting more dwell ... but this mainly needed at higher rpm
- Instead of a new dizzy, you could install a Pertronix kit, then the points trigger the blackbox which fires the coil
- The newer coils (without ballast) have a higher voltage output, so they can run big plug gaps to fire lean mixtures. But a points setup would burn up from the extra current (hence need for electronic ignition retrofit)

But if you don't need it, don't bother ...
