Any engine in any car what would it be?
#15
12cyl Rolls-Merlin(P51 mustang engine)in a '38/39 Chev/Ford/GMC cabover truck. Once saw one in a semitruck(cab part/tractor only), at a drag strip. It had NOS, 10 tires, threw two foot flames from all 12 stacks and was even fast down the strip. With a good turbo set up your looking at 2000 to 3000hp!:-)
