Ceteris paribus, more displacement equals more power. Despite their obvious differences, if you added exact components two each, ie. a turbocharger system, the Duratec would be better. But you have to add in other factors, an important one being the size of the engine bay. If you were building the ultimate performance Contour, factoring in the size of the engine bay, you would use a four cylinder. But no one is trying to build the ultimate Contour, and each engine has its place.
Sleeper, I've said it before and I'll say it again, nice passes!
