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
