I read an article one in a car mag about some dudes that headed out to the junkyard determined to come up with the wackiest combination they could. They ended up taking a Ford Pinto and cramming a Cadillac 472 V-8 they found in it. Apparently they had to do a fair bit of body modification because they needed to remove the front seats and move the dash and firewall back enough to fit the engine in front and then drove it from the back seat.
