I've read that there is an adapter plate available to mate a Duratec 3.0 V6 to a MT75 gearbox, but has anyone done this with the 4x4 gearbox?

Does the sump just bolt up with the front diff or is it going to need a custom-built item?

The other engine I'm being tempted by is the Mustang V8 but the same questions would arise there.

And is it worth the effort for either of these?

I need more power...
