The Legendary AC Shelby Cobra 427 (CSX3300)

The AC Shelby Cobra 427 is one of the most celebrated and legendary sports cars of all time. Born from a collaboration between British craftsmanship and raw American muscle, it remains a symbol of performance, style, and exclusivity. Among the highly sought-after examples, chassis CSX3300 stands out as a pristine and historically significant vehicle, meticulously maintained and with a well-documented provenance.

A Legacy of Power and Performance

The Cobra 427 was developed in the mid-1960s as an evolution of the original AC Cobra. With input from Carroll Shelby, the goal was to create a lightweight sports car that could rival the most powerful European manufacturers of the time. The 427 version was fitted with a monstrous 7.0L Ford V8 engine, producing between 425 and 500 horsepower, depending on the tuning. With its tubular steel chassis and aluminum body, the Cobra 427 was incredibly lightweight, making it one of the fastest road-legal cars of its era. Its acceleration was blistering, reaching 0-60 mph in approximately four seconds, while its top speed exceeded 165 mph. This combination of brute force and refined engineering solidified the Cobra’s place in motorsport and collector car history.

The Unique History of CSX3300

Chassis CSX3300 has a particularly interesting history, as it was initially registered in the United Kingdom before later being imported to Switzerland. This transition from one country to another is not uncommon for highly desirable collector cars, but the extensive documentation of CSX3300 provides an exceptional level of authenticity. The 2007 UK Registration Certificate officially recognized the vehicle, confirming its legitimacy as an original AC Shelby Cobra 427. Years later, in 2019, it was officially registered in Switzerland, where it has been kept in outstanding condition ever since.
