Hypoid offset distance (distance the pinion gear is from the centerline of the axles) on a Dana 60 is the least of all the popular race rear ends. 9" Ford is the greatest. The greater the distance, the greater the angle of the pinion gear teeth making more friction. Here are some hypoid offset specs for you numbers people:

12-bolt Chev, 8.8 Ford, 8 3/4" Mopar, 8.5 10-bolt Chev - 1.50"
Dana 60, Dana 44 - 1.125"
9" Ford - 2.25"

Recently, I was helping to build a Dana 60 for a friend and he had an opportunity to buy a brand new empty housing. Out of curiosity, I weighed the housing when he brought it to me and then weighed an empty 12 bolt '67 Chevelle housing in my shop. There was only 12 lbs difference.
