I would rally like to see how you make a V8 fit. I really don't think there is room for this to be practical.
Given enough money and sufficient lack of common sense, a way could be found, but I don't know how much of a Contour you would have left.
This sort of reminds me of the guy that in the late 60's had a Chevelle running around Bakersfield with an Allison aircraft V12 installed in it. The engine took up so much room that the driver had to sit it what was once the back seat. When he could get the tires to hook up, it really screamed.
You could also do what a few have done in the past and just install a second engine. This has been done on cars a little as a Mini Cooper (Twini Mini) and as big as a Cadillac. One engine in front, and another engine in the rear.
I like a lot of engine as much as the next guy (or maybe more), but if it is to be a daily driver, you need to stop short of turning it into drag strip funny car.
