if the 396 would fit into a 92 camaro
Yep.
with out too much work
Nope, but easier than some.

82 - 92 Camaros are samo-samo, so the big V-8 will fit. Use standard small block frame stands and motor mounts. You will need to beef up the rear suspension, stiffen the chassis with subframe connectors and probably put in some stiffer front springs. Trans and rear end need to be strong enough to handle the load.
