Just a wild guess. Have you pulled the cap and made sure the cam is actually spinning the distributor shaft/rotor? Rotor center button contacting the cap when seated?

You might have power with the key on, but do you have 12v to the battery positive on the distributor while cranking?

Just to see if your problem lies elsewhere or with the dizzy/wires/plugs, I would suggest running a wire directly from the battery to a standard 1/4" female spade and plugging it into the BAT spot on the dizzy. This will give it full 12v constant. You'll have to pull the wire to shut it down, but this will tell you if the problem is in your wiring somewhere, or the actual ignition system.

If ground were the problem the starter wouldn't crank. If the distributor clamp is missing he may not have a ground to the distributor though.
