LT bellhousings are not removable while LS style are. I believe the bolt pattern is different as well. Can't use the same converter either. Someone else want to chime in? I'm sure there's more to it than just that.

Input shafts are different so are the converters.

You cannot swap transmissions between LT1 and LS1.
