Engine Date Codes

[hardav]

Does anyone -GM-Tech- know how I can tell what year my new engine is? Just put one in.

Is there a place on the block where GM casts in a date of manufactoring code?

IF so where is it and is it a code or does it just say 1-30-2007?

 

Since GM came out with a higher TQ and HP engine for their new 2007 6.0 liter trucks I am just curious if I have this engine.

The engine identification number is located on three locations. There is a label on the front of the right rocker arm cover (1), the rear of the left rocker arm cover (2), and a label on the right side of the engine oil pan (3). The engine identification number is used to track and distinguish the engine prior to installation in a vehicle.

The Vehicle Identification Number (VIN) Derivative is located on the left rear side of the engine block and is a nine digit number stamped or laser etched onto the engine at the vehicle assembly plant. If reading the identification number from the left, the following information can be obtained:

 

 

The first digit identifies the division.

The second digit identifies the model year.

The third digit identifies the assembly plant.

The fourth through ninth digits are the last six digits of the Vehicle Identification Number (VIN) .
