Actually, we had an LS7 that we just pulled out of a ZO6, and hoovering it over the H3 on a hoist, it appears it might fit in the engine compartment, if you removed the generator. However, you would have to pull the engine to change plugs, install the dry oil sump reservoir on the right fender, radiator and engine fan in front of the grill. Nice part of the LS7 is it has a small oil pan due to the dry sump system.

The engine upgrade will be in '07, the diesel, as H3 Builder says will be, most likly closer to '08 than first run '07 (if it does come to happen), and the V8 everyone is talking about will not be in '07.
