    The 7w3797 is the group number that contains the 100-7408 cam.

    7w3796 does not exist in cats database.

    My biggest problem with this engine is that somebody went way out of their way to hide the serial #'s. CAT had it down to the bare metal paint free block and their best guess is an 8PN prefix.

    We ordered the cam from an online parts distributor out of Florida(the name eludes me at this moment). The cam looked like it had been dropped on an anvil several times and drug behind a truck so we ordered the actual CAT camshaft. Eventually we did get our $ back on the first one.

    Thanks again for the help guys, this place rocks!
