Default What power can a Cosworth 7" rear diff take ?

As above, i am doing a restoration on my saph and its been converted to 2wd but is still running the 4x4 rear end with a 7" rear diff and as the engine is suppose to be around 400bhp i wasnt sure if it would take that abuse for long.

any help would be great
Thanks

Martin, it's the torque not the BHP you need to be concerned about..
