Cosworth DFV

The Cosworth DFV, short for Double Four Valve, is the 3.0-litre, 90 degree V8 that Cosworth built for Formula One and that, with its whole programme funded by Ford's European division and its engines badged as Fords for championship races, was the dominant engine in the sport for many years. It was the V8 development of the earlier four-cylinder, four-valve FVA, produced from a design by Keith Duckworth for Colin Chapman's Team Lotus, and it won on its debut in the 1967 season with Jim Clark. With a bore and stroke of 85.67 by 64.90 mm and a displacement of 2,993 cc it reliably produced over 400 bhp, reaching 408 bhp at 9,000 rpm and by the end of its Formula One career 510 bhp at 11,200 rpm. DFVs were widely available from the late 1960s to the mid 1980s and variants were also raced in CART, Formula 3000 and sports car racing.
