Dana 60 under 73 swinger..need id

There’s a hot rod article from 90 something titled “the flying anvil” about swapping a Dana for an 8-3/4 with the same gear ratio and drag testing before and after in a dart. The times were very close to the same, meaning that the extra weight of the Dana (unsprung weight at that, the worst kind!) was offset by the increased efficiency and reduced housing flex. It really doesn’t get any better when it comes to an axle for performance usage.
