I think V12 Jaguar Bell Housing is what you meant?

Looking around at specs, it looks like even the WC versions are only rated to 300 ft/lbs, that doesn't leave much wiggle room does it?

 

They sell high strength gearsets for the t5. But I also know people with stock economy t5s behind 460bbf with no problem

 

That's the bell housing supplier I've been looking at.

I'm told you need to stay away from the T5 trannys that came in the Chevy S10's. They have a smaller input shaft that isn't strong enough for the torque of the V12.

 

unfortunatly the only case that will fit right is the mustang case. so IMO buy a ford t5 core and rebuild with gm gears. It can be done, and they are not hard to rebuild
