18. Yenko Camaro 427
The Yenko family started a Chevrolet dealership in Canonsburg, Pennsylvania, in 1949. In the late ‘50s, when Don Yenko managed the business, the company turned to the performance car market. They started with a series of race-prepared Corvettes Don raced himself and then moved to full conversion jobs based on various Chevrolet models.

With the Camaro’s introduction in 1967, Yenko started converting it to 427 V8 power, selling them as Yenko Super Cars. In addition to more power, wild graphics, and a long list of options, Yenko even offered a factory warranty, heavily promoting his models. That’s why those Yenko Camaros were the most popular choice in a custom 427 V8 conversion on the regular SS. But they only produced those 427 Camaros for just a few years. The total production number was around 600 with just a handful left.
