he is going to need a wiring harness and a ecu for it and not sure if the plugs for the tranny are the same and i think the transmission bell housing is different because on f bodys you cant put a ls t56 behind a t56 i know there manual trans but the bell housing is the same as a auto.

You can put anything into anything. It is just how much work you want to do. We have a big block in a opel for instance.
In this case it does not sound practical though
