Since its introduction in the early 60’s, the Ford Mustang has experienced periods of highs and periods of lows. The good thing about the Mustang is that Ford has never taken its eyes off this iconic car. It is a testament to good old-fashioned engineering backed by powerful engine muscle. There have been many variations of the Ford Mustang during the years, and we’ll have a look at a few that seemed more special than the others. Some of these cars are limited-edition (less than 5,000 units) and some have large production numbers (more than 100,000) but they have one thing in common. They are the among the best muscle cars in the world.

Engine swaps have been around as long as there have been different manufacturers making a variety of models. Whether it’s putting a flathead V8 in your Model A Ford, or injecting some modern power into your aging musclecar, an engine swap can define an entire vehicle. Such is the case with this spectacular 1967 Mustang that’s dressed up like a Shelby GT500 and packs a 2004 Mustang Cobra power plant under the hood. That means 32 valves, a supercharger, and drivability that they couldn’t imagine back in the good old, bad old days.

The rest of the car was updated as well, but the basic goodness of the Mustang shape was retained, along with the very best Shelby upgrades, creating a Pro-Touring fastback that has to be seen to be believed. Built by the guys at Pro Touring Super Cars (a division of Speed, Inc.), this was a cost-no-object car from the beginning. Speed, Inc. specializes in putting late model power into vintage muscle, and bringing the latest technology to bear on the cars of the past. What better way to do that than build a Shelby GT500 tribute with one of Ford’s most potent late-model powertrains? Read more!
