The gears are bigger on a 70.

In a high HP application the Dana 60 gears would be the weak link.

I dont know how much more would a Dana 70 weight....50lbs?? I dont think thats too much specially if its on the rear end...

I wonder how much HP would a Dana 70 Detroit Locker take. It would be the same as a 60 for sure....so how much can it take???

Im asking this because I wonder what could hold behind a pro charged pump gas HEMI making 1600 hp- or 2000hp on pump gas and a pro charger I dont know if thats even possible...
