It is also a great reference when buying an "original" car. As some options for some cars were not identified by the factory apart from the original build sheet, the book only tells you about the numbers that you can find on various components. As an example, a 1970 SS was not identified by any of the numbers as an SS except on the build sheet. However, as any knowledgable enthusiast knows, the build number of the car (6 digits) is also stamped on the front of the block.
All in all a great book. Excellent for the Classic Chevy enthusiast Library.
