A833 O/D What will it handle?

You were talking about the gears being wide it works pretty good for what I am running right now. Its in my truck but the 318 magnum that is in it is a low end torque maker anyway the cam I put in it is good from like 1500-6000ish I dont pull it much above 6k on the stock bottom end. It has 4,56's in the rear. I just wanted to see because I plan on rebuilding my a833 but with future engine upgrades planned I didnt want to rebuild it to just snap it.
