LT1 T56 Transmission to LA 360 swap

I appreciate the input. It looks like it will cost me approx 500 in parts to convert it back to an LS type t56. Out of curiosity, why do people look for viper t56 and Challenger tr6060s over LS Camaro t56s? Other than being stronger, they don't seem to make the swap any easier since the bellhousings can't be used unless I'm mistaken.

Considering it will cost me $2000+ not including clutch/flywheel for all the parts to make the swap It doesn't seem worth it unless Im missing something.
