    I posted this quesiton in some Scout forums, but since I'm on here so much I thought I would give it a try.


    "We are rebuilding a 72 Scout 258 cid 6 cylinder with D44 axles. The
    stock ratio is 4.27. We are planning 33"-35" tires for mostly local
    off road use but also some driving on pavement around the area in a 50
    mile radius on an infrequent basis. Any suggestions as to 4.88 v.s.
    5.13 ratio for the new gears? Does anyone know what the stock ratio
    engine rpm would be at 55 mph, or 65 mph, if it will even go that
    fast?"

    5.13's are pretty steep. Id go with the 4.88's. Also, I'd dump the 258, and drop a V8 in. The 304 is a good motor, and would give more torque to aid in spinning the tires. Cant give input on the rest, as you didnt give tranny info.

    Transmission is a Warner T-18 4 speed. Low gear 4:1. Transfer case is a Dana 20 low gear 2:1. All Stock.

    A V8 would be nice. I kind of like the sounds of a turbo diesel though. Unfortunately the budget isn't going to allow for an engine swap anytime soon. Way too many other issues to address.
