Would the newer 3.5l and 3.9l engines possibly be interchangable without any serious modification?? I know on the cougar forums, they are swapping out the 2.5l v6 engines for the 3.0 v6 engines in the taurus. I appreciate any help... -Nate

The engine in the Aztek is OHV, not OHC. The new (2004) 3.5L and the upcoming 3.9L are based on the same block as the 2.8L/3.1L/3.4L 60-degree V6. Depending on where the mounting points are, they should all be interchangable.
In the case of the Ford engines, the 2.5L Duratec engine from the Contour/Mystique/Cougar is basically the same structure as the 3.0L DOHC engine from the Taurus/Sable/Escape/Tribute.
