Need a little swap advice

[Old Dude]

Greetings motorheads. i'm a nubie on this site and need a little advice. My 94' 3.0 Ranger is on the downside of 265k and running good but I need to think about new blood under the hood. I want to go with a 4.0 but I'm leaning towards a SOHC versus working over a late model OHV motor to get added horsepower without a serious loss in MPG. What's the downside here? Other than electrical? I would appreciate your comments if you have done this swap or didn't and why. Peace

get a 97 up ohv. Best running years for them, and to my knowledge the least amount of problems.
