Zora at the General Motors Desert Proving Grounds in Mesa, Arizona, behind the wheel of a 1954 Corvette test mule equipped with a small-block Chevy V8. Zora was testing his new “Duntov camshaft” in preparation for an attempt to break the 150-mph mark on the sands of Daytona Beach in January 1956. The Duntov Cam helped the engine produce 240 hp @ 5800 RPM, 15 hp more than the stock engine.
