Ford Super Snake 427 CI V8 – 650 Horsepower
Ford built a lot of great muscle cars back in the day, but it was the engines under the hood that truly transcended the car industry. Although the Mustang wasn’t considered the most powerful, this one was. The 427 cubic-inch V8 engine had a specific tune and design that delivered a serious amount of power (via Motor Authority).
Although this Mustang is an extremely rare one, it broke the mold for performance. There are very few powerful V8 engines from this era that changed the game like the Super Snake. Every inch of the engine was designed to perform better than the competition. Of course, Carroll Shelby was at the helm, so that helped the cause in a massive way.
