[YENKO DEUCE REGISTRY]

I also thought these listings were misprints, I can't speak for the ZL1, but the 427 '70 Yenko Nova is a 'maybe'.

There are 6 Gobi Beige '70 Yenko Novas found to my knowledge, 4 are in PA. One of these 4 is a second owner, 4speed, p/s, DEMO car that the current owner purchased by taking over the payments from the original owner. This second owner blew the original LT1, and traded it even up for a 427 engine which he then installed in his Deuce. This particular car is painted black, and the stripes are painted on in silver, with red pinstripes. I would be surprised if this is the same car that TOM406 is referring to, but it's possible.
