    Because Freightliner ordered the engine in bulk or not for a specific build. Frieghtliner installed the flywheel after they decided what truck it was going in. How to go about getting the frieghtliner serial number is anyone’s guess

    What are you trying to accomplish with this motor?
    That might get you some better advice.

    I wouldn't wish that swap on my worst enemy.
    Go with another 7.3 or at least a DT466.

    Just for starters you will need a custom wiring harness for the CAT ecm to even get it to start.
    Don't know the year of the truck you have but if it has a body module you are in for an even bigger nightmare.
