    Check your numbers here

    the 3970010 is just the cating number. It pretty general and will give you the round about year (sometimes) Get all the numbers and check this website

    Get the numbers stamped on the front passenger area of the block. On my truck it's behind and underneath the alternator...there's a machined boss at the part line between the block and the passenger head.

    Then go to www.mortec.com
