Corvette Timeline: The 1960 Debut of Zora Duntov’s CERV-I
November 20, 1960 – Duntov debuts his CERV I at Riverside International Raceway in California
Zora Arkus-Duntov always knew how to make an entrance. During the United States Grand Prix weekend, he rolled out his newest experimental machine—the CERV I. This sleek car was nearly the same size as an Indy racer, and it certainly didn’t look anything like a Corvette. So, what was Duntov planning?
Duntov builds an Indy 500-sized race car for engineering purposes
Size wasn’t an issue. If Zora had wanted to enter the CERV I in the Indy 500, the car would have met the technical requirements. Chevrolet and GM were never going to field an Indy race car, but Duntov liked to compare performance on equal terms. That’s why the CERV I matched Indy car dimensions. The mid-engine layout was also forward-thinking. Indy would not see its first mid-engine (or rear-engine) entry until the 1961 Cooper T54.
The CERV I also served as a test bed for independent rear suspension. This was an early version of the system that would eventually reach production on the 1963 Corvette Sting Ray—though the production unit was far stronger and more robust. And then there was the all-aluminum small-block Chevy engine.
Zora Arkus-Duntov’s big dream for the Corvette, a lightweight, all-aluminum engine
Duntov had wanted an all-aluminum SBC since 1957. However, simply casting the existing small-block design in aluminum turned out to be much harder than it looked. The lightweight and inexpensive SBC had been engineered for cast iron. Early aluminum versions struggled with strength and durability, especially in racing conditions.
(You can read more about this in my story on the 1963 all-aluminum 377 SBC engine—HERE!)
Chevrolet finally found a successful approach with the Mark IV big-block. This led to the legendary 427 ZL-1, an engine that collected plenty of racing wins. Remarkably, it took 37 years after the CERV I for an all-aluminum small-block to become standard in a production Corvette. That milestone arrived in 1997 and marked a major turning point in Corvette engineering.
