The car in the photos has none of the characteristics of a factory BB Camaro.
Once upon a time there were three Yenko lists and that VIN was on a couple of them. The lists were compiled using copies of copies of the hand-written Yenko inventory sheets and were often hard to read. For that reason, there is a disclaimer at the top of the Supercar Registry.
The is the second instance of a car on one of the lists being located that is clearly not a factory 427 Camaro.
