Actually Shane, you are both right. Autolite and MC plugs are like Motorcraft and Bosch TFI modules. Made by the same company to two different sets of specs.
You gotta watch those cheapo plug wires too. I had some awful misfire issues right after I put a fully dressed (right down to plug wires) engine in my truck. I finally found it while I was adjusting the PS line trying to get a pinch out of it. I brushed the coil wire without touching the body and got the zap of my life.
Grabbed my low-mileage MC plugs wires off the old engine and she's been fine since.
