It may not always be practical to check, and I don't know exactly when the tradition started, but the Willys blocks are generally hand-stamped on the oil pan gasket surface as to the day the bottom end was assembled for the first time, or maybe the day the machining was completed. It's usually stamped near the rear main bearing cap, or right around the corner from there on the side, but the oil pan gasket conceals it.
