3.0 taurus engine

The 2.5/3.0L Duratec V6 engine is Ford designed. The 2.0L/2.3L 4V 4-cylinder Duratec is Mazda designed. The new 3.5L 4v V6 Duratec is Ford designed but I believe Mazda is involved in design responsibility for the 3.7L version.

So, what point about compatability are you making here??

For clarification: At this time, only the 3.0L Duratec is a known swap candidate.
