It's also important to note that the V6 700R4's, either the 2.8 or the 4.3 versions, used lighter duty clutch packs than the V8 models. There is usually one to two fewer clutches and steels in each group on a V6 trans. They can be modified to accept more, but it requires machine work to the face of the piston in each pack. They will still work behind a V8, just don't be surprised when they burn up prematurely.
