Yenko Chevrolet was a Chevrolet dealership located at 575 West Pike Street in Canonsburg, Pennsylvania. Operating between 1949 and 1982, the dealership is best known for selling customized muscle cars in the late 1960s. Referred to today as "Yenkos," they are among the most collectible 1960s vehicles.
Yenko Chevrolet's history dates back to 1929, the year Frank Yenko opened a Durant dealership. After Durant folded in 1932, Yenko opened a Chevrolet dealership in Bentleyville in 1934. In 1949, Yenko opened a second Chevrolet dealership in Canonsburg.
In 1957, Frank's son Don took over the dealership. Known for his modified Chevrolets, Don ran the dealership until 1982, at which time he sold the business.
In 1966, Don Yenko was impressed enough with the late model Chevrolet Corvair's handling, and decided to apply for SCCA approval of the Corsa model for racing. The sanctioning body approved the cars with back seat removed and upgrades to the Corsa engine increasing horsepower and torque. The 100 1966 Corsas that received certification were all painted white with blue striping, and were named "Yenko Stinger".
Yenko continued to modify Corvair coupes as Stingers for the rest of the car's production run. The last Stinger was a 1969 coupe, after which Corvair production ceased for good at Willow Run, Michigan.
When the Camaro entered the pony car fray in 1967, Yenko transplanted Chevrolet's 427 cubic inch (7 L), 425 horsepower (317 kW) L-72 engine (along with other high-performance parts) and created the Yenko Camaro. The 1967 & 1968 427 Camaros were so popular that, in 1969, Yenko used Chevrolet's Central Office Production Order (COPO) system to have L-72 engines installed into Chevrolet Camaros, Chevelles, and Novas on the factory assembly lines.
In 1971 Yenko sold the Chevrolet Vega Yenko Stinger II with a modified Vega aluminum-block 2.3 inline 4 with a turbocharger and 155 hp. Chevy did not take the hint on its marketing potential as neither the Yenko-requested higher-compression engine blocks nor factory equipped turbo engines were ever built. The Stinger II was offered from Yenko Chevrolet through 1973. The high performance and limited production of all Yenko-modified cars makes them valuable and prized to collectors.
On October 14, 2009, General Marketing Capital Incorporated (GMCI) announced its ownership of the Yenko trademark and its plans to revitalize the brand and at SEMA 2009, unveiled the 2010 Yenko Camaro prototype.
