Engines assembled in Flint with the single digit year code were used in both passenger and Corvette applications. All cylinder blocks, cylinder heads and cast iron intake manifolds cast in Saginaw, Michigan, for the Flint, Michigan, engine assembly plant would have a single-digit year date code. These were the Flint, Michigan, and Tonawanda, New York, plants. There were two plants that were casting cast iron parts for Chevrolet engines during this time period. What we hope to accomplish with this article is to familiarize you with how and where to look for casting numbers on the 1970-75 Camaros. These casting numbers were compiled from the original Flint Engine Plant build records and extensive Tonawanda records as well. This 2nd Generation Camaro casting number breakdown list is the first to ever be published anywhere. Both the information pertaining to each engine component and all pertinent information relating to each specific engine option are listed below the model year headings. In this article we will cover the identification of all these major engine components for all Camaro engines from 1970 through 1975. The 1970-75 Camaros used a variety of blocks, cylinder heads, intake manifolds, exhaust manifolds, and waterpumps.
