The most "significant" Chevrolet performance car.

[copo69]

I agree with Verne on the '63 Z11. By significance, this car had to be a major influence on the popularity of later Chevrolet muscle. Car was more competitive and much more specialized than the ZL1 plus they were easier to sell. Many ZL1's lost their motors to boats and other race cars or were motors were pulled just to sell the cars. While they had a weight advantage even Jenkins said the iron motors made more power. I'm a Camaro person but feel that big Impala was more significant. I think the runnerup would be the early Z28's in TransAm.
