In 1966, Don Yenko was impressed 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 and most had blue striping, and were named "Yenko Stingers". 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 at
Willow Run, Michigan. Charlie Doerge wrote a book on the Yenko Stinger and some of Don's escapades in 2011. The book lists many original and subsequent owners, as well as known racing history with much information on all of the cars that were produced. Jay Leno in a video has declared it "the bible for Yenko Stinger owners". When
Camaros, classifiable as a "
pony car", became available in 1967, Yenko transferred
Chevrolet's 427
cubic inch (7 L), 425
hp (317 kW)
L-72 engine (along with other high-performance parts) into some Camaros, creating 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 and
Chevelles. During 1971 and 1972, Yenko sold Yenko Stinger Vegas. Based on the Chevrolet Vega GT Hatchback, Stinger Vegas included front and rear spoilers and Yenko Stinger side striping and a special COPO engine with alloy-plated forged aluminum pistons. The modified Vega aluminum-block 2.3
inline 4 with a
turbocharger and 155 hp required a 50,000 mile test for EPA certification and Don Yenko eventually decided against using the turbochargers. Chevrolet was not interested in the marketing potential of a Turbo version as neither the Yenko-requested higher-compression engine blocks nor factory equipped turbo engines were ever built. The Stinger Vega was offered from Yenko Chevrolet through 1972 without turbochargers installed, but Yenko did offer the turbochargers as an aftermarket kit. The high performance and limited production of all Yenko-modified cars makes them valuable and prized to collectors. ==Production numbers==
