Crab distributor triggering MSD.

Points from Ford sixes from '49 to about early '70's are easy to come by.. they are also used on old Ford tractors....Bob L

It seems like a smaller point gap would cause the points to open farther up the ramp on the dist cam which would alter the timing by delaying the trigger event.With a crab dist. and not much timing adjustability available, you should stay with stock point gap.

Good reasoning. However, varying the gap could be used to one's advantage. Since the points are no longer responsible for controlling dwell, changing the gap could actually be used a a method of increasing the available timing adjustability without compromising coil saturation.
