Not Champion spark plugs I hope....
I had an ignition module bad that would only hit on every other cylinder. or every 3rd cylinder anyway...

I think you might have set the timing 180 degrees off. This is a common mistake when rebuilding an engine and have done it myself. Usually you will get a slight backfire. Try turning the distributor slightly if it don't start try moving it 180 degrees.
If you have compression spark and fuel + air it should run.

was any work done on it before this happened ?

any symptoms lately ?
