Hahaha good luck with that! I think the only MAF 351's that were OBD-I/EEC-IV (95 and earlier) were from California! Everybody AND their brother are looking for that computer my friend!

I'm honestly not sure. If they were an aftermarket item, they would be so high in price because of a high demand. Your options at this point are to find that PCM, do a MAF conversion by using what I believe is a Mustang PCM, with a standalone controller for the E4OD, or get a 96 351 with MAF and settle for the OBD-II/EECV,

I have heard that some of the 5.0 PCMs will cause leaning above 4500 RPM on the 5.8. If I were convinced there were no problems, I suppose that would be an option as well.

The truck will start and run with a 5.0 processor, and a little aftermarket tuning can help to dial it in for a 5.8; which basically consists of changing the displacement values so load calculations are correct for fuel and spark.
Is this just a stock swap (no modified/aftermarket parts) or are there are go-fast goodies involved with this swap?

It is an Accel system that provides spark through 12 degrees of crankshaft rotation. It smooths the idle, provides more torque and improves fuel economy. At least that has been my experience. It is a piggy back system that plugs into the stock ignition system and works through the stock distributor with no changes to the computer.

FWIW, I've never had aftermarket ignition components make a major difference, over stock TFI components, unless they were bad to begin with.
I still use the stock ignition system, on my supercharged truck, and it idles great and performs quite well. Those aftarmarket ignition components/systems aren't cheap either, and can be a little overkill for a stock motor.
