Here is some more info on that.

An altered 1/2 distributer base and shaft was installed. It was the base with just the shaft sticking up. The original timing gear was put on the test shaft. The motor was turned over without plugs. The shaft was just held in by gravity. This procedure was done with a small amount of lateral pressure put in the side of the exposed shaft and then agin with no pressure. There was absolutely no pulsing or any other type of irregular movement on the exposed shaft. It spun straight and true.

So still open to suggestions because we are out of ideas on this one.
