Of all the Cobra variants the 427 Semi/Competition or S/C is the most desirable series. Built from Shelby’s competition production line, these were purposeful race-cars that were prepared at the last minute for the road.
The story of the Cobra begins as early as 1959 when Carol Shelby raced for Aston Martin, winning the 24 Hours of Le Mans. Along the way he probably took notice of a well performing AC Ace that would become a foundation for his next venture.
After quitting racing, he return to America to build his own sportscar, turning to Charles Hurlock of AC Cars to supply a chassis and body that was suitable for the new 260 cubic inch Ford V8. After considerable racing success, Ford provided the even larger 427 FE engine. By 1965, chief engineer Ken Miles wanted to fit thengine to win SCCA’s A Production Class and stay ahead of the Corvette Grand Sport.
