i copied some info: look the 70 wins hands down

DANA 44
All domestic manufacturers have used Dana axles, and the 44, with its 8 1/2-inch ring gear, is likely to be a step up on anything smaller than a 1/2-ton. A narrowed 44 could be the hot ticket for vehicles smaller than a full-size sport-utility. It was standard under the front of pre-1976 Chevy Blazers and 1/2-tons, solid front-axled F-150s and Broncos, and Jeep J-10/J-20s and Grand Wagoneers.

DANA 60
A Dana 60 looks deceptively similar to a Dana 44, but the 60's 9 3/4-inch ring gear diameter is a major factor in strength. It can be found in many 3/4-ton pickup and van rear ends.

DANA 70
Almost identical in appearance to a Dana 60, the Dana 70 is standard in heavy Dodge pickups and GM duallies. The large 10.54-inch ring gear diameter will tolerate much torque, and is suitable for diesel power and/or big tires.

Bah, its still small. Look under the rear end of my truck and compare ;)
