After hinting at a new Shelby GT500 in L.A., it looks like Ford will finally pull the cover off its latest snake in Detroit. We don't know all the details, but reports suggest the new Shelby should have over 700 horsepower (522 kilowatts) when it debuts – widely believed to come from a supercharged version of the GT350's 5.2-liter flat-plane crank V8 – and should tip the scales at around 4,225 pounds (1,916 kilograms).
