    According to www.mortec.com it could be any of these three..

    3970010....302.....69....4...Z-28 Camaro
    3970010....327.....69....2...Trucks and industrial
    3970010....350...69-80...2 or 4

    Have you pulled the pan to see if it's 2 or 4 bolt mains?

    It seems that he found its a '75 so it would fall into the last category... to bad its not one of those '69 DZ 302 engines.

    The date casting should be on the passanger side back of the block.

    Find the casting numbers on both heads under the valve covers.
