For timing, use manifold vacuum, under the throttle plate. Advance the timing to the maximum steady vacuum, then back off just a bit, maybe 1/2 inch of vacuum. Tighten down the dizzy and test drive it. During the test, lug the engine just a bit and listen for ping. If no ping, you are finished. If it pings, back it off just a bit more.
