Perhaps one of the rarest of muscle cars, the 1969 ZL1 Camaro featured a jaw-dropping 500 horses under the hood in an aluminum V-8 engine. This bad boy American beast could go from 0-60 in about 5.3 seconds, which was why some of the 69 models made found their way into drag-racing. Over time, the full complement of cars was sold; however, the package option was never offered again.
