What are the differences between the 8 3/4 & the Dana 60?

Some 440 GTX's 4bbl got Danas, also, stick cars

Dana is heavy as hell, and if you shorten one out of a "truck" it's even heavier because heavier axle tubes Takes a LOT of HP just to turn it

Consider the "best alternative" a Ferd 9". Stronger than an 8 3/4, better parts availability, and a pumkin' you can easily swap gear ratios. In my opinion, the Ford 9 is easier to deal with, setup, etc, than a Dana

A mech. friend of mine that works in a machine shop after retiring , told me that a 9" ford took more h.p. to turn than a dana 60. He has a low 8 second vega w/ a 350small block , WITH a dana 60 in it ---------jfyi .
He is changing the rollcage and going to add nitrous to it to put it into the 7`s---------------
