Yes it was "rated" at 380hp but it actually made close(r?) to 500hp. Supercharged AND based on the Cobra R engine?! Lol.. that's why C&D and MT got 102-104mph trap speeds.
Ford did that on purpose to avoid taking sales away from the Mustang.
Ford's "new" F-150 5.0 regular cab short box weighs 4100-4200 lbs and makes 400hp... it does 13.9-14.1@103mph...
