Having wiped the floor with a Dodge Viper, this awesome McLaren 650S has been on the hunt for more American machinery to make a fool of. And what better than a gorgeous Ford GT that's been tuned by Heffner Performance to deliver over 700 horsepower from its 5.4-liter supercharged V8. According to Drag Times, the McLaren is totally stock, with its 3.8-liter twin-turbo V8 continuing to deliver 641 hp.
Despite having almost identical power-to-weight ratios, the ten years of tech that separates these supercars looks more like 20 when they hit the street.
