with my k5 engine dead, and gas prices getting out of hand, i may be selling it and getting a smaller 4x4. i really like the blazer, and it always impresses me offroad. but, keeping it fueled was kicking my butt. are you guys familiar with how many miles per gallon a jeep will get? i'm talking about the various open-top versions, like the cj5, cj7, wrangler, etc, with various engines. 4 bangers, jeep 6cyl, dodge 318, chevy 350 or 4.3L swaps, etc. any info you're willing to give would be appreciated. my friend's 1990 gets crappy mpg (about 12 on our last roadtrip), but we think his wimpy 2.5L 4banger might have a lot to do with it. just has to work too hard. considering my 4.3L gets about 20mpg in my extended cab c1500, i bet it would do great in a little jeep.
