Ford Racing took a Ford Focus RS and stuffed a 5.0 L Cammer V8 crate motor into it. Ford chose the RS version because of its sportier Euro appearance. The DOHC V8 produces 420 horsepower and 365 ft-lb of torque. Ford Racing sells this engine for $14,995 on their site. They converted the car from FWD to RWD using a Tremec five-speed manual transmission and a Ford Racing 8.8-inch rear end.
