DIYAutoTune.com customer Jay Brown of Minneapolis, MN, has become a household name in Drag Week competition. His 1969 Mustang “Shelby 500 Clone” graced the cover of Mustang Monthly Magazine and continues to impress with its unique naturally aspirated combination, powered and controlled by MS3X Engine Management.
Engine & Power
Jay’s Mustang runs a 585 cubic inch SOHC Ford Cammer engine, making a staggering 992 horsepower naturally aspirated. Developed on Jay’s own home engine dyno, the engine showcases his relentless innovation and passion for building outside the box.

Why This Build Stands Out
What makes Jay’s Mustang special isn’t just the rare SOHC powerplant, but how he uses MS3X to harness and refine nearly 1,000 horsepower in a reliable, repeatable package. With three Drag Week class championships under his belt, Jay has proven both the durability of his build and the capability of MS3X in real-world competition.
