22. 1969 Yenko Camaro 427
The Yenko family started a Chevrolet dealership in Canonsburg, Pennsylvania, in 1949. In the late ’50s, when Don Yenko started managing the business, the company slowly turned to the performance car market, first with a series of race-prepared Corvettes. Don himself raced with complete conversion jobs based on various Chevrolet models (via American Muscle Car Museum).

Very soon, with the introduction of the Camaro in 1967, Yenko started converting it to 427 V8 power and selling them as Yenko Super Cars. In addition to more power, wild graphics, and a long list of optional extras, Yenko even offered a factory warranty and heavily promoted his models. That is why Yenko Camaros were the most popular choice if you wanted a custom 427 V8 conversion on your regular SS.
