I have a engine block with following numbers...In the valley is 117 011 04 01 and on the upper driver's side is 117 983 12 311186....The bore is between 3-9/16 inches and 3-5/8 inches. It has a nice crank with new bearings...What is it for-what application...sounds like either a 450 or 500 series...thank you....Jim
