Well... The problem I think you'll run into is that the 4.0L was never produced with a distributor. You need the computer to control the coil packs. I think you're pretty well stuck. I dont know if the 4.0L block still has the provisions for a distributor or not, but I doubt it.
I'd put serious thought into going to a 302 if there's room for one.

Agreed - so many more options and even when you go 302 EFI. A9L computers are a dime a dozen.
4.0 has a camshaft position sensor, later ones anyway. It also runs the oil pump. Not sure if any distributors were ever designed to pop into this spot at the back right side of the motor.

91 and mybe 92 Explorers used only the crankshaft position sensor then 93+ used the camshaft. Mine is a 93 CA truck and it has the cam sensor. Maybe, not sure, but maybe all year CA had the camshaft sensor. Reason is CARB and smog control. I know CA used sequential fuel injection (each injector fires independent) and Fed used multiport (each R/L bank fires injectors at the same time). So perhaps a cam sensor is more accurate for use on the sequential?

No one has ever produced a carb manifold specifically for the 4.0, unless it was a one of that I haven't heard of. The only thing that might come close is the 2 and 4 barrel manifolds made by offenhauser that were produced for the earlier 2.6 cologne v6. I've heard that these manifolds work on the 2.9 with some modification, and considering the similarities between the 2.9 and 4.0 it might be possible, although I don't know how the ignition system can be overcome. The 2.8 with a fairly aggressive cam and a 4 barrel offenhauser intake with a 390 holley can actually make lots of power, so modifying what is already installed might not be a bad idea. Just a thought.

I have looked into carbing a 2.9 extensively and The 4.0 would not be much different. The 4.0 Never came with a distributor. The 4.0 block is just a modified 2.9 block and the 2.9 distributor will work, only the deck height is different on the 4.0. The bad news is that nobody makes a standalone 2.9 distributor for use without the computer. The 2.8 distributor wont work because it has a different gear and oil pump drive. I have tried to modify a 2.8 distributor by putting the 2.9 gear on it, but the shaft diameter is different. this was the point that I gave up because just making the distributor work entailed almost a complete fabrication of a new dist. Another difficult aspect of this conversion would be the intake because the manifold also partially covered by the valve covers, so even a custom sheet metal manifold would require some machine work as well as welding.
