Have to repower my 94 2.5L. I'm running 33's with a 2.5" lift and would like some more power without decreasing my fuel mileage greatly. Currently I'm getting 13mpg and am wondering if a rebuilt 4.0L would get about the same. Also want to know what I would have to purchase to do the swap from the 2.5L and where to get the best price for a rebuilt block. Any suggestions and opinions would be greatly appreciated

Currently I'm getting 13mpg and am wondering if a rebuilt 4.0L would get about the same. My budget is tight and want to know what I would have to purchase to do the swap from the 2.5L and where to get the best price for a rebuilt block.

That's not what I wanted to hear. Do you think a rebuilt 2.5 will have a noticeable power increase compared to the one I have with 178k? Is there any affordable ways to boost power like cold air intake?
I just did a replace my 2.5 with a rebuilt 2.5 was. $1586 for motor and there is a big improvement I'm running 235 75 r 15 and can run 55 at 2500 RPMS in 4 gear big improvement form old motor
Last check I did for MPG on mine was about 12.5mpg with 4.5" lift, 33x12.5's, and 4.0L with 5-speed.
There's not much that you can do for adding MPG's in these. The aerodynamics are on par with a bus. You can try reducing parasitic losses like a better flowing exhaust. You can add a cold air intake, that might add a tenth of a mile per gallon. Removing the mechanical fan and replacing it with an electric fan on a controller relay would add maybe half a mile per gallon. I did that on a 2.3L Ranger that I had and saw a slight increase in mpg.
Hopefully I have some time to think about it. My motor runs ok but noticed some water in the dipstick. Changed the oil and didn't see any in there but it doesn't sound good
