Sometimes the distributor cap can be bad. This is sort of common on Chevy small blocks.

The backyard mechanic trying to save money often overlooks simple problems like a cracked distributor cap, faulty coil, loose connections etc etc.
If you can afford 4 cars and buy performance equipment for them, I think you can afford to take them to a qualified mechanic.

If the heads were removed, distributer not set in the cam gear properly, Timing chain off a tooth. Else the firing order wrong (wire crossed). or distributer mis adjusted. Broken rotor button. valves to tight. (Adjusted before they had proper oil pressure).

72' I think plug wires might not be in right orcer
77" I'm thinkin' vaccuum advance is bad
84" I'm thinkin' vaccuum leak
92" thinkin' idle position sensor
at this point, this is all a guess

not enough info on any of them to diagnose correctly, try re-asking each question individually with all the info you can for better (more intelligent) answers
