Forty years ago it took a lot to get a car to run 10s in the quarter-mile. You needed a BIG engine, open tuned headers, a giant gas sucking Holley carb, slicks, ear plugs, and a lot of NERVE! Today, it’s no biggie for a performance car to run low 11’s. Lingenfelter Engineering has been able to get a mildly modified ZR1 to run low-to-mid 9s with ALL of the stock creature comforts. All you have to do is HOLD ON!
July 4, 1971 was a great day for America, Corvettes, John Greenwood, and Bob Johnson! At Michigan International Speedway, Greenwood and Johnson picked up a big win in a 4-hour endurance race in a field of 36 cars.
But when Zora and his team unleashed the all-aluminum ZL-1, jaws dropped and eyes popped! The thought of a solid-lifter, 12.5:1 compression, big carb 427 that weighed as much as a small-block was just OUT’A SIGHT! FAR-OUT! GROOVY, MAN!
Explore how John Greenwood transformed the C4 Corvette into the radical G Supercar series — wide-bodied, aerodynamically aggressive and engineered for extreme performance. Blending racing heritage with street presence, Greenwood’s G Corvettes reimagined the C4 as a world-class machine capable of standing alongside elite European supercars.
