I think the hp/torque rating of rears is primarily a function of ring gear diameter, the larger the radius/diameter, the more torque it can handle. Dana 44 is 8.5", which is what's in vipers. Chevy 12 bolt I think is 8.875". I think a Dana 60 is about 9 1/2", which is what was in hemi cars.
They're all strong enough.
