I just watched the video that they have on line and it describes the car accurately. It indicates a Berger sold Nova SS that was originally equipped with a 350 and a 4 speed. The man made it quite clear that he was unaware of exactly when the 454 was installed. I would say that would be an accurate representation of the car.
