*UPDATE: We've received an official press release from Ford quoting power figures of 662 horsepower and 631 pound-feet of torque, making the 2013 Ford Shelby GT500's engine the most powerful production V8 in the world.
Originally, Ford was rating it at 650 hp. If they updated and added 12 hp, they would not under rate it over 100 hp.
Like I said do a little digging, there are numbers everywhere. What amazes me even more than the rwhp of the 500 is the incredible rwtq numbers.
