Hi Folks

I picked up a distributor machine and have been fooling around with it a bit. The picture is the plotting of 4 different distributor advance curves. The associated tech info is from my 1971 Demon with 180lbs cranking compression. Let's hear your thoughts on the different plottings and how they would react in my combo. FWIW, the engine runs with about 17 HG manifold vacuum (idle), and the vac cans will give me another 18 degrees at that level.

Thanks FABO

Edit: The OEM distributor is of unknown origin.
