1. Locate the serial number:
The serial number is usually stamped on a metal plate or tag attached to the engine block. It may also be stamped directly onto the engine block itself.
2. Decode the serial number:
- First two digits: The first two digits of the serial number indicate the year the engine was manufactured. For example, if the first two digits are "09", the engine was manufactured in 1909.
- Third digit: The third digit indicates the plant where the engine was assembled.
- A = Flint, Michigan
- C = Tonawanda, New York
- F = Livonia, Michigan
- G = Saginaw, Michigan
- K = Kansas City, Missouri
- L = Romulus, Michigan
- M = Defiance, Ohio
- N = St. Catharines, Ontario
- P = Parma, Ohio
- R = Ramos Arizpe, Mexico
- S = Silao, Mexico
- T = Toluca, Mexico
- V = Flint, Michigan (VIN engines)
- W = Windsor, Ontario
- X = Doraville, Georgia
- Suffix Code: The suffix code typically indicates the month and year the engine was assembled, but this can vary depending on the engine type. For example, a suffix code of "AB" might indicate that the engine was assembled in February of 1970.
By decoding the engine's serial number, you can determine the year it was manufactured and the plant where it was assembled. This information can be helpful when restoring or identifying a Chevy engine.
