You can see pics and read some history on the car at Kevin's site. They claim it was the first 427 Yenko Nova so maybe Yenko just pulled a non SS car off the lot and converted it although they do say it was a 396/375 car. If it was built as a COPO 396/375 you would think it would still have the SS trim like the COPO Chevelles did. It would be interesting to see what the rear end code is - if the original one is still in the car. He has a fantastic collection of cars. Does he have an e-mail address or someone who will answer some questions on the cars?
