It’s without a doubt one of the best horsepower bangs for your buck on the market today. In fact, the Ford
Mustang has always been a bargain since it first premiered in mid-1964. But say if today’s stock Mustang GT doesn’t quite do it for you? Sure it’s got a wonderful V8, but you just gotta have more. Fortunately there are options, and two of them are the Shelby GT500 and the Roush Stage 3, producing 662 and 675 horsepower respectively.
