ignition what? coil, swicth,module, lock cylinder? gm Jim
I would replace the ignition module in the distributor.
it does not run smoothly and not all plugs fire when supposed to Addition to above: No spark or intermittent spark, a problem that was fairly common back when distributors had vacuum advances was that one of the wires going to the pickup coil (pole piece) would break from the back and forth movement of the pickup as the vacuum advance would move it to control the timing, symptoms would be no start or that it would start and when you put a load on the engine and the vacuum dropped the vacuum advance would start to move the pickup coil, the broken wire would open the circuit and the spark would die.To check this problem was fairly simple by removing the cap & rotor and tugging lightly on the wires where they go into the pickup coil/pole piece, if one of the wires was broken you could see it and knew you had to replace the pickup coil which GM called a pole piece (magnetic pickup coil and pole piece are the same thing).
You need to replace the Distributor cap with a factory GM cap. be sure to check the coil wire where it goes into the coil, pull it out and it should be shiney on the end. If not replace coil and wire too. That will fix it.
The Hall effect.
The pickup coil in the distributor? !976 should be an HEI distributor. Take the cap off, unplug the wires going to the distributor, remove the rotor and the pickup coil is under the rotor and held in place with two screws.
