    I assume by 350t you mean 350 ft-lbs of torque?

    If done correctly a 7.5" can handle more than that.....
    I'm told mine will take over 500 in it's current form. The locking unit is rated for 800....

    Then again I see you were talking about the 7.8.....

    As said before a similarly built up 8.8 will be stronger than a 7.5 barring some part defect.

    Look..... you can make a 7.5 do crazy things if you build it right..... Take mine.... it's a 7.5 with a detroit Tru-Trac locker, Ford Racing 4.10 gears, Moser C-Clip Eliminators, Yukon Axles, T/A performance rear end cover with main supports and fully welded Axle tubes..... I am pushing over 500 RWHP and close to 500 ft. Tq. to the wheels with 295/45/17 M/T drag radials. CHE upper control arms and maximum motorsports lower control anti hop bars. I'm running low 11's with no problems.....

    Now I have snapped axles and c-clips but that was when the rear was in stock form. I have been told that this rear setup the way it is that I can handle 700HP with no problem..... The only problem is will the floor boards.... I have to next weld on battle boxes to prevent the torque from ripping the floor apart....

    any question on these rears, please feel free to ask....

    Yukon Axles
    I'm hearing REAL good things about Yukon products. The whine fro the Richmonds I threw in ('cause NOBODY had a set of FRPP 3.45's) @ 40 MPH is ever so slight, but it's enough that I want to swap them out....and yes they were installed correctly. The whine has been constant. Hasn't changed a bit.
