A833 NP A body trans ID help & intro.

Been missing for a while due to getting hit by a semi rolling about 90 on i10 interstate in Arizona 3 years ago. Concussion, neck injury, and reconstructive surgery to arm and shoulder. Lots of painful physical therapy but happy to get to 85%. While taking my 833 apart I discovered that someone dropped the the trans and on the bottom is a spider crack silver dollar size. Found a aluminum OD case and tail housing that was converted to 307 main bearing. Looks to be excellent machine work and I didn't pay much for it. Hopefully all my regular 833 internals will drop in. Anybody here seen a conversion like this? Strength wise, do you think this will handle the 360 # 5302006 block "roller"
