Before he saved the Corvette, Zora Arkus-Duntov saved the Ford Flathead. In New York after the war, he and his brother Yura founded Ardun Mechanical Corporation. The name combined their two surnames: ARkus and DUNtov. Ardun manufactured aluminum overhead valve cylinder heads for the Ford Flathead V8, the engine that built hot rodding, the engine that every speed shop in Los Angeles was trying to make faster. The Flathead's fundamental weakness was its side-valve architecture: the valves sat in the block beside the cylinders, restricting airflow and trapping heat. Ardun's OHV conversion moved the valves to the top of the combustion chamber, cured the chronic overheating, and dramatically improved breathing. The company that saved the Flathead's top end grew to 300 employees. Then went bankrupt. Duntov's first American engine venture ended in financial failure. His second would define General Motors for seventy years.
In January 1953, Duntov walked into the GM Motorama at the Waldorf-Astoria in New York and saw the Corvette prototype. He was 43 years old. Belgian-born to Russian-Jewish parents. Educated at the Technische Universität in Berlin, where he specialized in engine development and supercharging and graduated in 1934. He had raced motorcycles in Germany. Served in the French Air Force. Fled the German invasion to New York. Built the Ardun heads. Crossed the Atlantic again to work for Sydney Allard in England, helping develop the Allard J2 that won its class at Le Mans in 1952 with a Ford Flathead running Ardun OHV heads. Co-drove for Allard at Le Mans in 1952 and 1953. A Belgian educated in Germany who had already improved a Ford engine, raced at Le Mans, and gone bankrupt once, walked into the Waldorf-Astoria and saw the most beautiful car Chevrolet had ever built powered by a warmed-over version of the six-cylinder that had been in Chevrolet trucks since 1929.
He wrote a letter. Not a fan letter. A technical paper. Addressed to Ed Cole, Chevrolet's chief engineer. The letter appraised the Corvette's strengths and weaknesses with the clinical precision of an engineer who had spent two decades working on performance engines across three continents. The car looked right. The engine was wrong. The chassis was wrong. The two-speed Powerglide automatic was wrong. The Blue Flame six-cylinder was wrong. Everything underneath the fiberglass body was wrong. Cole read the letter and hired Duntov on May 1, 1953, as an assistant staff engineer. The man who had built OHV heads for Ford was now working for Chevrolet. The man who had raced at Le Mans for a British manufacturer was now developing a car in Detroit. The most improbable hire in General Motors history turned out to be the most important.
Duntov pushed the V8 into the Corvette. Cole's new 265 small block, the engine we covered in the Turbo-Fire post, replaced the six-cylinder for 1955 and transformed the Corvette from a styling exercise into a performance car overnight. Duntov designed the solid-lifter camshaft that bears his name, the "Duntov cam," which pushed the 265 to 225 HP in 1956 with aggressive valve timing that no Chevrolet production cam had previously attempted. He drove a Corvette at Pikes Peak in 1956 to prove the car could compete in real motorsport. He set a two-way flying mile record of 150.583 mph on Daytona Beach in a modified 1956 Corvette. He developed the CERV I (Chevrolet Engineering Research Vehicle), a mid-engine open-wheel experimental that tested suspension and drivetrain concepts a decade before mid-engine Corvettes became reality. He fought GM's corporate racing ban from inside the building, secretly supporting Corvette racing teams through back channels the same way Vince Piggins supported Camaro racing through COPO orders.
He retired as Corvette chief engineer in 1975 after 22 years. He died on April 21, 1996, at age 86. His ashes are interred at the National Corvette Museum in Bowling Green, Kentucky. The Father of the Corvette is buried inside the building dedicated to the car he saved. A Belgian. Educated in Berlin. Who built heads for a Ford. Who raced for a British manufacturer at Le Mans. Who wrote a letter to the chief engineer of Chevrolet and spent the rest of his life proving that the car he saw at the Waldorf-Astoria deserved better than a truck engine and a two-speed automatic. Everything the Corvette became, from the 265 to the LT2 in the C8, started with that letter.
