Vin numbers on big blocks

They didn't put VIN's on them at all before 1968, then in 1968 it was on the top rear of the block near the oil galley, by where the bell housing bolts on. Starting in '69 they started putting it on the side just above the oil pan rail. I can't answer the whole vs partial VIN question, I'm not sure. I've never seen one with the whole VIN that I can remember.
