Fifty years after the original Shelby GT350 a new one is now available in dealerships. Ford rates this 2016 Shelby GT350 at 526 hp but it wasn’t until we drained out the premium pump gas and put 98 octane Sunoco race fuel through it that we were able to see those numbers. To our surprise switching fuels netted a gain of 25.5 horsepower with this car.
