1968
Encouraged by the success of the 1967 model, Yenko continued to produce his Camaros. All cars came equipped with the M-21 close-ratio four speed manual transmission. A large, twin-scooped hood replaced the "Stinger" version, and Yenko badges graced the sides and tail light plate. The COPO model came with upgraded suspension, 140 mph (230 km/h) speed and other items but not the 427 ci engine. Yenko swapped the 396 ci engine for these up until 1969 when they were installed by Chevrolet. There is speculation that one 1968 Camaro came from the factory in 1968 with a 427 ci engine making it one of the most valuable collector cars to exist.
As of Sat. Jan. 17th 2009 at the Barret Jackson Auto Auction, a rebodied, silver 4spd Yenko went for $121,000
