Ant,
My 416 stroker puts out over 500 ft pounds torque and I have ran the 8.8 in it since I built the car with only one problem. I broke the Ford posi. I then had it upgraded to 31 spline axels with a heavy duty Eaton posi in it and it is almost bullet proof. A couple of others around here run them with more power than I have and they haven't had any problem.
