Bellhousing Breakage

[Tom Goldman]

I see way more BOP cases with cracked bells than Chevys, so either the case is weaker or the big BOP's just have too much torque.
I'd start with a fresh case and go with an Ultrabell. Stronger ,safer and a lot easier to get than the multifit cases.
I'd definitly check the driveline alignment and the mount either way.

Manual trans guys are used to checking bell housing alignment and installing offset dowels. I just wonder how much is the bell and how much is the placement of the dowels in the block. I don't know if you can use an empty T350 case and check its alignment to the crank centerline, but I'd try something to verify it.

Also, you might look into motor mounts with restricted flex (or steel mounts) with the stock type trans mount.
