Having used 4.7-liter engines in the MkI, Shelby switched to 7.0-liter units for the MkII. The powerplants were actually taken from the NASCAR-spec Ford Galaxie, but modified for road course use and bolted onto heavy-duty, four-speed transmissions. The original engine was rated at 485 horsepower and 475 pound-feet of torque and had a 7,400-rpm redline.
