That's one reason I stated the 4.0L EFI engine should do better than a 232. Only 10 more inches, but port injection = even fuel distribution, and computer control keeps it in better tune all through the trip. 

The gear thing is a touchy one! To tall a gear and the vehicle may excell in mileage on the highway, but get really bad in town/overall average mileage. I think the 4.0L would be really happy with a 3.31 on the highway, loafing along at 1800-2000 rpm and  60-67 mph (26" tall 205/70R15 tires). As I mentioned before, I know for a fact that 3.08 gears suck gas in a 3500 pound vehicle! That would be 65-70 in the same 1800-2000 rpm range w/3.08 gears. I currently run 3.55 gears, which gives me 56-62 mph in that range. 

The EFI has a slight hesitation when you floor it from a dead stop, maybe 1/3-1/2 of a second. That's just enough the car starts moving before the computer realizes you want as much power as you can get (or maybe it's built in so the engine won't hesitate from the sudden increase of fuel?). So it won't spin on dry pavement unless there's a bit of sand or something to let a tire slip. Then the rear locks (limited slip) and the car slips sideways as the tires spin, so you can't keep it up long. But if the road is wet, or otherwise slippery, it spins to easy if you hit it hard! It would be sort of nice to get a little chirp from a dead stop, but I'd give the chance of that up with 3.31 gears. Still, I may just go to 3.31 gears. Shouldn't give to much feel of power up. And who needs to spin the tires? With a standard diff it was to easy to spin -- dangerously so! I had to be very careful pulling out into traffic with wet roads!!
