Switched plug wires with another one, still had the same problem. Checked to make sure the spark plug with the wire attached has spark, and it did.

Since you posted *proper testing* has confirmed there is sufficient compression and fuel delivery (?) - the only thing I can think of is the long spark plug boot has failed and is letting the spark jump through it to a metal ground when it is installed on the spark plug - as in the metal spark plug tube .... Also be sure there is no oil ponding up inside the spark plug tube as that will also cause a misfire .. Based on posted information - I strongly suspect the spark plug wire is the culprit! (Ignition coil is 'inside' the distributor) Good luck with it!

Coil location??? Rotor installed correctly.
