Born from Anglo-American Collaboration The Cobra 427 was the result of a partnership between British manufacturer AC Cars and American racing legend Carroll Shelby, who installed powerful Ford V8s into AC’s lightweight chassis.
Powered by a Massive 427 Cubic Inch (7.0L) Ford V8 The 427 Cobra was equipped with a Ford 7.0L big-block V8, producing up to 425–485 horsepower, depending on the spec — delivering brutal acceleration in a lightweight body.
Blistering 0–60 Time Thanks to its power-to-weight ratio, the Cobra 427 could rocket from 0–60 mph in under 4 seconds, making it one of the fastest production cars of the 1960s.
Wider Body and Chassis Than Earlier Cobras The 427 version featured a new coil-spring chassis and wider fenders, designed to accommodate the larger engine and massive tires — giving it its iconic muscular stance.
Feared and Respected for Its Raw Power The Cobra 427 earned a reputation as "unforgiving but exhilarating", with massive power, no driver aids, and a tendency to break traction with ease — not for the faint of heart.
Very Limited Production Only around 260 original 427 Cobras were produced between 1965 and 1967, making authentic examples extremely rare and valuable.
Also Available in S/C (Semi-Competition) Trim Shelby offered the 427 in S/C (Semi-Competition) versions, which were lightly detuned race cars for the road — and are among the most collectible Cobras today.
Outperformed Ferrari and Corvette on Track With its raw torque and low weight, the Cobra 427 beat Ferrari and Chevrolet on American and European circuits, helping Shelby win the FIA World Manufacturers’ Championship in 1965.
Spawned Countless Replicas and Continuation Models Due to its iconic status and limited numbers, the Cobra 427 has been one of the most replicated cars in history, with continuation models made by Shelby American and others.
One of the Most Valuable Classic Cars Original AC Shelby Cobra 427s can fetch $1.5 to $5 million or more at auction, depending on provenance — making it not just a performance legend, but an investment-grade classic.

The AC Shelby Cobra 427 (1965–1967) is one of the most legendary and valuable American sports cars ever built, with only approximately 260 original 427 models produced. Its combination of brute power (7.0L V8) and lightweight British chassis makes it a multi-million-euro icon.
