Then it sounds like the problem is ahead of any cap or rotor or plug or plug wire problem. That leaves me suspecting low voltage on the coils high input terminal BUT THE HOT WIRE THE COIL TRICK should have eliminated that one such as a high resistace ignition switch etc.

Next possibilities (you claim a different coil made no diference) are a weak condensor or a high resistance shorting path somewhere between the coils low (to distributor) side terminal and the igniton points terminal,,,,,,,,or burned points,,,,,,,,or a resistive ground path in the distributor to its ground.

Hot wire the coil again to insure a good voltage supply to its input,,,,,,,,try a different condensor,,,,,,,,,,check the wires from coil to distributor n to the points for any weak links or shorts including the insulated pass through wiring stud on the side,,,,,,,,,use a jumper wire to establish a good ground for the points,,,,,,,,,,,give her 2 aspirins n call me at the Office as Im about runnin out of smarts here lol
