Dana 60 S60 or Ford 9"

I'm not a Dana hater, as I've said before I have a S-60 in my car and it's been flawless.


Guys keep stating the Dana is stronger and takes less power to run but never have any numbers to back it up.

How much stronger does a good aftermarket 9" case need to be? There are plenty of guys going 1.0-teen 60' that aren't having any issues breaking them, so apparently they are strong enough. How about the power to run them? If there was any ET to be found by dumping a 9" and going to a Dana the fast heads up guys would be doing it. Also if the Dana was faster, changing the gears out at the track wouldn't be an issue, these guy are smart enough to have the pinion shims set up ahead of time to make the change faster. The aftermarket support for the 9" has been mentioned but don't think that if there was a strong demand for Dana parts, (mainly pro gears) there wouldn't be companies making them.
