Caroll Shelby and Jack Roush, some of the best known tuning experts around came together to create a masterpiece neither one could do alone in the Ford Mustang SR-71. This car will be up for sale and auctioned for charity. This insane ride came to be after inspiration by the Lockheed Martin SR-71 Blackbird with “SR” standing for nothing less than Shelby and Roush. As far as performance modifications, the Roush & Shelby Mustang SR-71 comes with a 5.0L Ti-VCT V8 engine complemented by a 2.3L Whipple Twin Screw Supercharger and a Roush intake. These tuning experts also updated their SR-71 with a new exhaust from Ford Racing, a new handling pack, and reinforced roll cage. We are all waiting anxiously for the release of these Ford Mustang performance figures.
