I was flipping through the Grand Wagoneer Performance Portfolio last night (bed time light reading...) and in the early 1980s the carbed 258 engined FSJs were getting ~20mpg (+/- 2 MPG).
A modern 4.0/AW4 in one of these beasties must be a decent setup for MPG. I think the modern 4.0 has better hp/tq then the stock 360 IIRC - or close to it. You wouldn't be losing anything I think.
