Almost all cars that drive the distributor off a chain driven camshaft or
jackshaft would have counter clockwise rotating distributors, but cars with
gear driven cams (two gear systems) have clockwise type distributors. My
Martin engine is one such, as might be other performance modded engines. If
you drive the distributor shaft with a belt, you could just put a single
twist in the belt to make it run backwards.
I suspect that even a sewing machine motor (one of the old ones that you can
pick up for almost free at flea markets) would drive the distributor just
fine, and they come with speed controls built in...can anyone think of a way
to read the advance directly on a gauge, rather than using a timing light?
BTW, now that you've mentioned it, I might make up a machine this winter -
it sounds like a fun project! (my wife brought home a sewing machine table
for her NEW machine that still had the old machine attached, so I've got the
bits already!)
