what kind of oil filter do you use?
This knock is typical of Ford 302's. Usually a weak pump will cause it. Also if your running a crappy oil filter without a anit-drainback check valve, that could do it, but from seeing the mile on this block, it is time for a rebuild or a new pump but who knows what the bearing looking like.
