What Are Chevy Engine Numbers?
Chevy engine numbers are serial numbers located on the engine lock of Chevrolet vehicles. These number contain valuable information about where and when the engine was manufactured, as well as its capacity and statistics. Sometimes they also contain the VIN number of the vehicle in which they were originally installed.
All Chevy engine numbers are stamped with the date and location that they were produced. This information is fairly simple to decode. The first letter in the engine number corresponds with the name of the manufacturing plant at which the engine was made. The next four number correspond with the month and day it rolled off the line. The final three-letter code explains what vehicle, including its year, the engine was made for.
