I’ve been doing a little hunting lately about the 1981 Yenko Turbo Z Camaros. You can blame this affliction on video games…I hadn’t thought about the Turbo Z cars in years, but while building up a 1979 Z28 in Forza, I found someone who did great Yenko liveries and next thing I know, I’m twenty open tabs deep into all things Don Yenko. And during this information binge, I came across two cars that he tweaked on that I knew absolutely nothing about:

This Nova that ran in IMSA, done up like a police package vehicle, and…

…a Citation X-11.

While I’m still struggling to see a Citation X-11 as a successor to the Yenko Stinger Corvairs, the IMSA Nova looks properly badass and could’ve been done up as a street car with minimum impacts…the 9C1 suspension was stout and V8s were still in place.

Just when I think I can’t learn any more about what’s been put out there, I’m always surprised, so today, I want you to hit me with what one-off builds from the factories or tuners that I may not know. Indulge this information binge, please.
