Ok i know this sounds pretty basic and you might have already checked it but are all of the plug wires plugged in? Are they connected to the correct spot on the distributor? Remember this one turns ccw instead of clock wise. The jumping signal is probably just the msd. It fires over 20 degrees of crank shaft rotation. Back in the 80's i had a 455 pontiac with a msd7 and when i put it on a SUN machine i could see that the plugs were each firing 5 times instead of just once. Imagine what that looks like on a timing light. Oh and bosch has stopped making the igniter coils for these distributors. So if yours goes it might be time to just give up and go to EFI.
