    Vin anywhere on the engine? GM 5.3 Gen V

    I hear a lot of people talk about the VIN being on the block by the head.
    My complete engine has numbers all over the place but they are all 16 digits, there is no 17 digits that corresponds with a VIN. I know my engine came out of a Silverado pickup truck, I have no clue what the vin is.

    GM quit doing that many years ago. If you have the PCM out of the same vehicle the engine came out of the VIN will be in the calibration. Why do you need the VIN?
