Alan,
I was thinking of changing to full electronic instead of points too. But is an electronic Mallory better than an electronic Lucas dist? What is the gain from using Mallory? So for now, I'll tune the dual point I guess.
I have a Pertronix that I'll put in the 3A so probably use the Pertronix coil with that and take your suggestion and look at the Mallory coil for the dual-point.
