Anyone Running A Mechanical Voltage Regulator 67 Dart 273 2bbl

One day it would be interesting to run a points regulator with the cover off and see how quickly (or slowly) the points move between the positions.
Back in about 69, I did just that on my 57 Chevy; it's amazing. tiny sparks flying around,yet the points seem to just quiver, moving to fast for the eye to follow.

sorta like points in a distributor machine.
