A highly desirable 1966 Shelby 427 Cobra Roadster is scheduled to cross the block at Mecum’s Glendale 2026 auction, giving collectors a shot at one of the most iconic American performance cars ever produced.
One of Only 260 Ever Built
Identified as CSX3355, the roadster is one of only 260 Street 427 Cobra models built, a figure that places it among the most sought-after variants in Shelby’s entire lineup. Finished in red with a black interior, the car carries the unmistakable presence and raw performance that defined the big-block Cobra era.
Power That Built a Legend
Power comes from a 427 cubic-inch side-oiler V-8 paired with a 4-speed manual transmission, a combination closely tied to the model’s reputation for aggressive performance and hands-on driver engagement. The Cobra’s lightweight roadster body and powerful engine helped establish it as a benchmark for American sports cars throughout the 1960s.
A Documented Production History
The vehicle is equipped with bucket seats and knock-off wheels, details that align with the period-correct character expected of a genuine Street 427 Cobra. Its production background adds real weight to its appeal. Records indicate the car was billed to Shelby American on Dec. 14, 1966, before being stored at Crown Auto throughout 1967. It was later transported to S&C Motors of San Francisco alongside CSX3320 and CSX3325, and invoiced by S&C Motors on April 26, 1968.
The Cobra’s documented history includes recognition in the Shelby Registry, further supporting its provenance and authenticity, factors that carry significant weight among serious collectors and enthusiasts alike.
Crossing the Block in March
Scheduled to cross the block Saturday, March 21, during the Glendale 2026 auction, the car represents a rare chance to secure a genuine big-block Cobra with verified production details and period-correct specifications intact. With limited production numbers and enduring demand for original Shelby-built examples, this offering underscores the lasting significance of the 427 Cobra as a cornerstone of American performance heritage.
Mecum Glendale will be selling over 2,000 collector vehicles at the State Farm Arena March 17-21. Visit their website to see all consignments and collections, buy tickets, and register to bid onsite or online.
