    If you have a 327 the casting number is usually located on the rear on the left or drivers side on top of bellhousing.
    Keep smiling, it only hurts when you think it does!

    on the back upper side there is some med.. size numbers starting with a 3 more then likely like 397 or some thing like that go to this site it will tell you everything you need to know about s/b in
    b/b chevy engines.... http://www.mortec.com/castnum.htm
    go to small blocks casting numbers have yours off the block first.
