Engine miss under load - ignition concerns

I'll 2nd the "yes" for the 5.9L. It still has a single coil and a distributor. The spark driver is built into the engine controller and with more modern electronics (similar to GM HEI), so doesn't need a ballast. But, the basics are the same. The main upgrade is that the distributor doesn't apply any spark advance. That is all done electronically by the computer, which gets rpm & Pman signals. But, that hasn't changed from the 1980's where Chrysler's "spark computer" did the advancing (my 1982 Aries). The Magnum engines use a crankshaft pickup instead of in-distributor as in 70's A's. There is a pickup in the distributor, but that is a "cam pickup" for "sequential" fuel injection timing.
