The Shelby GT500 is one of the most storied Mustangs ever built. If you wanted an original in primo shape, you’re going to spend well into the six-figures and you’ll have a rare machine that you might be hesitant to drive because of its value and lack of modern driveability. Today at the ROUSH Performance booth at the SEMA Show, Revology Cars unveiled its latest creation — a 1967 Shelby GT500 powered by a Roush-supercharged Coyote engine.
