The 4.0 ohv is a good little engine. The 4.0 sohc is also a good engine. The ohv is very dependable as is the sohc. The early sohc is prone to timing issues. But the sohc is the more powerful of the 2. The sohc has a higher rpm range and more bottom end power. However the ohv seems in my opinion to get better mpg's. If I was going to swap one for the other considering the time and money involved. I would go with a 5.0
I agree 5.0L. I had rangers with both the OHV and SOHC. Both were great. 200k on the OHV before I sold it. 140k on the SOHC and still going, but soon to be a V8. SOHC is a bit more peppy than my OHV. The one thing about the SOHC is it has lots of plastic internals that can get brittle over time. I wouldnt reccomend swapping a high milage SOHC as a replacement. If you are going to pull your engine you are halfway to a V8 swap. Some members even claim better mpg afterwards.
I had a v8 expo that got the same mileage as my 4.0. To me it seemed the 5.0 had more down low but the 4.0 had more top end. But keep in mind it was a factory 5.0. It shifted right when it was making good power
