Block VIN   |   Application Codes   |   1962-63   |   1964   |   1965   |   1966   |   1967   |   1968   |   1969   |   1970   |   1971   |   1972   |   1973   |   1974   |   1975   |   1976   |   1977   |   1978   |   1979

Engine identification may be determined by finding the engine block VIN and the engine application code in the following tables. On 4- and 6-cylinder engines, the code is stamped on a pad on the passenger side of the block to the rear of the distributor and above the fuel pump. V8 engine codes are stamped on a pad forward of the cylinder head on the passenger side of the block.

Along with the engine code you will find the engine block VIN. Block VIN codes were started as early as 1962, and became manditory in 1968. Some early blocks may not have the GM division stamped.

The codes have been compiled from many sources to make this page as correct as possible. There is no guarantee that the codes are complete or accurate, therefore, I cannot accept any liability or responsibility for damages incurred from the use of this information. It is my intention to help you as much as possible in deciphering your Novas engine code.

Good Luck and Happy Motoring!
