    Just off the top of your head any idea on the mileage you made to and fro BB03? Been watching all of your upgrades with the engine and what not just curious what a 6.2 did with that highly modified of a flying brick mileage wise /forums/images/graemlins/ears.gif /forums/images/graemlins/thinking.gif 12-13mpg?

    I averaged 16.2 mpg both ways and spent no more than $20 on fuel for wheeling while in Moab.

    I think it could have done a lot better, but spinning 2600 rpm on the freeway isn't the best range for mileage. I'm gonna start either hunting for another NV4500 or look into getting the one I have rebuilt. Whichever is cheaper I guess...

    Then I can bolt up some 35's and still run at a much lower rpm for long trips...and not wear out my 40's. With the NV4500 and 35's it'll cruise at 2050 rpm at 65, which should get me near to 20 mpg.

    I have one...but it's in pieces and needs a few parts. I may just try and see if I can't get that one together and maybe run a 241 behind it. SYE and a really beefy skid pan and I think it'd be just fine.

    Hwat would dictate your decision to go with 241 vs 205? weight, using stock driveshafts, lower 1st gear.....

    Well, the 205 isn't a direct bolt in deal. The 241 is, and it has a lower low range, and it's about 80-90 lbs lighter and a SYE is available and not that spendy.

    My crawl ratio would go from 59:1 up to 70:1...

    The only thing I'd do is find a way to clock the 241 up a bit and build a very beefy skid pan under it.

    Well I am doing something similar, using a klune v in between and that can let me clock it any angle I want plus a little more crawl ratio.
    Only problem here is the $$$$ /forums/images/graemlins/rotfl.gif

    lol try the 3200 rpm I ran at the whole way to Moab from Phoenix. Then 2900 from Moab back to Canada. I am way to scared to figure out what kind of mileage I was getting /forums/images/graemlins/eek.gif

    Yeah, but I have a diesel and the redline is only 3600 rpm. 2600-3000 is OK for a small block...
