8.75 741 case strength?

Hootie, I can't comment on the going rate these days, but the 741 case is plenty strong for your combo. As long as your getting a "A" body housing that's a bolt in, your in good shape. If it comes with backing plates, brakes, drums, etc.....all the better. It should be fine to get you down the road for now. Keep in mind, driveshaft length will be a issue with the swap also.
