stock bore is 3 3/16, .125 over makes it 3 5/16, a 1/16 =.067. i think you read the measument wrong, who knows what crank was installed, no easy way to know with out pulling the pan or one head, 3 3/4 " stroke is ford ,4"stroke is merc, a good merc crank adds $400 to the value of the engine, good block and merc crank = $800
