I doubt very much that the painted engine block is insulating ground from the distributor. You may notice that the bottom of the dizzy has a collar that sits on top, but under that is still a thick aluminum ledge that makes contact with the bore in the engine block. If that bore is clean and unpainted, your dizzy is grounded. Aside from that, the dizzy hold-down bracket gives electrical continuity from the bolt, thru the bracket to top of engine block. Scrape paint off under that bracket, and bolt it back down. It will be grounded.
I am betting on bad condensers right out of the box. Gotta keep you fingers crossed nowadays when buying these chinese made junk condensers. If you have a known good one, keep it till hell freezes over. Are you sure you have the right capacity?
Make sure rotor arm is making good contact with lead pile on underside of center of dizzy cap. If rotor is not touching that lead, it won't start. Lot of new ones now are smashed down too much and don't touch. You may need to pull up a little on that arm, but not too much or it will wear the lead off that center tower in the cap.
How about a coil test to see if it's any good. Autozone may text it for you for nothing.
