It's all in the gearing; my 232-powered station wagon has a 3.33? axle and runs 65 - 70 mph all day. Air-cooled BW auto trans. Fully loaded hauling a camp trailer and krap four 3 people for a week it'll do 60mph all day on the flat and level. it did that too with a Carter YF. 2.72 seems like a steep axle. Is it 4wd? Is the 4-wheel stuff that much of a power loss? Maybe too-tall tires for that axle? -------------- next part -------------- An HTML attachment was scrubbed...
