Umm, maybe you should actually look at a focus. It has a larger engine bay. It has also has a tunnel under the car that is perfect for the RWD driveshaft. And have you seen a 302 in a focus? It looks more at home in the engine bay than a zetec does. Though yes a v8 conversion can be done on a contour, it will take a LOT more work than it does to make it work on a focus, and a LOT more money.
