That would stand for Don Yenko. He would be kind of like Shelby is for Mustangs. He built special edition Camaros, Corvairs, Chevelles, and Novas. I believe they were pretty popular in the SCCA circuits, and considered some of the hotest stock Chevys ever put on the market. They have become pretty rare now so an original can fetch a pretty penny.Originally Posted by TheGreatSatan
This would be a striping job that is unique to Yenko.
As for the different packages .. There was the RS, SS, and the Z28.
Those packages can actually be combined such as the RS/SS or RS/Z28 etc etc. The car you have shown appears to be a RS/SS. The RS package is what gave it the headlight covers.
Z/28 package alone didn't have the covered headlights.
So instead of searching for the 427 Camaro you should probably look for the RS, SS and Z28 designations. The 427 wasn't available in the Camaro in 1969 through normal dealerships. It was considered a COPO (Central Office Production Order) car and was only available to certain dealerships, race teams, and organizations such as Yenko.
Hope this helps and really looking forward to what you come up with.
