I'm not 100% certain, but I'm reasonably certain it won't.

One thing I am certain of, even if it could bolt up, that 5 speed (probably a TK5, though it could be either of the Mitsubishi transmissions) wouldn't hold up very long to the torque of a V8.

Correct on both counts. It will not bolt up and your trans wouldnt handle a v8 if it would. The m5od was put in the explorers behind the 4.0 and also in broncos and f150's with a diff bellhousing and it is pretty marginal. Stout behind the v6's though

In my build I've got a 302 with a C4/C5 hybrid. And it's taken the test of time and use.
Make sure about the tooth count on the flex plate. If I remember correctly they have a 164 and a 157 tooth. Then make sure the engine plate that goes between bellhousing and block matches or the starter won't bolt up. Of course use the right starter also.
For a donor I used a 1980 or might have been an 81 Merc Cougar for the 302, bellhousing and the engine plate. C4 came from a friend that I bought it off of that was in a 302 Mustang.

4.0, its a hell of an engine in my rig, I'm severely undergeared when I'm not shifted into double low and it will still light both back tires up, I'm locked with 35's. simple swap really, it will bolt right in and then requires some wiring. very simple wiring, hell I figured it out, and I'm half not there 80% of the time
