1967 The V8 Cosworth–Ford DFV (double four valve) engine was important for British motor racing, as Coventry Climax had announced it would no longer produce racing engines. Jim Clark won the Dutch grand prix in a DFV-powered Lotus in 1967. The DFV and its derivatives went on to dominate F1 racing until 1983. It was also used in formula two, three, and junior races with considerable success, and DFV-engined cars won the Le Mans twenty-four-hour race and several American speedway races. The key to the engine's success lay in Duckworth's precision in the use of a narrow angle, four-valve-per-cylinder, twin overhead camshaft cylinder head layout, which other firms had to acquire or develop themselves to remain competitive. Based on an off-the-shelf engine, it was sold to independent firms such as Brabham, Tyrrell, McLaren, Hesketh, and Wolf.
