Have you verified the cam and valve timing. Sounds like the timing chain may have jumped.

Pull the valve covers and check all the rocker arms for looseness.

While you had the valve covers off, did you give the push rods a spin with your fingers? If they are bent, they will be a lot looser than if they are still straight. If you have a helper, have them crank the engine, while you have the valve covers off, and see if they all move the same....

Now you need to find out what caused the distributor to lock up. It could be internal to the distributor, or the oil pump could have locked up, or the cam locked up (least probable).

also keep in mind that you need to have the correct type of gear on the distributor. If you have one made from the wrong material the cam will eat the teeth off. In this case it sound more like something siezed though...
