AC produced only 23 AC Cobra 427 competition roadsters. In 1966, one was selected and converted into a special model called the 427 (CSX3015) “Cobra to End All Cobras.” The first one of these was originally part of a European promotional tour before its conversion. This conversion called for making the original racing model street legal with mufflers, a windshield and bumpers amongst other modifications. But some things were not modified, including the racing rear end, brakes and headers. The most notable modification is the addition of Twin Paxton Superchargers, TPS. Shelby crafted two 427 models by himself adding a TPS.
