You're correct, I've seen a few cars with yenko emblems. the most memorable was a 1968 z-28, with a sticker on the valve cover and on the drivers side back glass. The stickers read, "Tuned by Yenko, Cannonsburg Pa."

This corvette has the same sticker. But like i said, it is a LS-6 454, and it was phased out in early 71. This is a 72 model. I'll try and get some numbers and more info. Thanks for the help so far!
