First generation Ford Mustang enthusiasts know that the fastest 1965-66 Ford Mustangs are the Shelby GT350 2+2's. Most of these limited production Shelby's were thinly disguised SCCA race cars that were built for the street for homologation purposes. A scant 36 of them were full-on racing machines that dominated SCCA B production racing in 1965 and 1966. These beauteous beasts are still vintage raced to this day. They're often competing heads-up against 1963-65 Shelby Cobra 289-powered roadsters.
