In the early 1980s, the best combination to bring to the Indianapolis 500-mile race for some hot competition was a March Cosworth with a chassis by March Engineering and a Cosworth-Ford power plant. During that era, a series of Cosworth-powered cars dominated Indy Car competition. Cars of this type took the 500-mile race starting in 1983 and continuing through 1987.

The March-Cosworth was basically a turn-key entry for any racing team to run in the Indy 500 during that time frame. There were a dozen of these cars at the starting line up at the 1983 version of the “Brickyard Classic.”

A British based engine builder, Cosworth had roots going back to 1958 in London. That’s when Mike Costin and Keith Duckworth founded the firm. The company had a long-standing association with Ford that started with modifying Kent engines for Formula Junior racing. Cosworth also developed engines for Formula B competitors, sports racing cars and street cars like the Lotus Cortina.

The Double Valve Four (DFV4), or “double four-valve,” engine was an iconic Cosworth creation. It was developed at the urging of Colin Chapman of Team Lotus and aimed at the Formula 1 Grand Prix race market. The DFV4 won 167 races over a 20-year period. It is considered a legendary motor.

In 1975, the DFV4 was de-stroked to 161.7-cid. and fitted with a turbocharger. Designated the DFX after that, it became the favorite engine of Indy Car racers and dominated that series throughout the 1980s.
