It was used on older manual transmissions. The z-bar pivot ball goes there. Its a linkage that would operate the clutch fork before hydraulics got popular.
The one in the very center of the pic, the dark one with the rust around it, is where the horizontal oil passage was drilled through, from the oil filter output to the vertical passage in the center rear of the block. It either gets a pipe plug (as in Joe's pic), or in some applications, the oil pressure sending unit. It is at the left end of the passage with the long arrow pointing to the right in this diagram. You can also see the head of the plug (hex head, rather than square drive) in the drawing, with a smaller arrow pointing at it.
The one up toward the top right, that you can see light through in your own pic, is the later-introduced one of 2 in the block for the old skool clutch bell crank shaft stud, starting in about the late 60s. I've actually made a bracket to put the stud on in that location, in a late 60s car, that I was putting a much older 283 into. The one down low to the left of that was the original one in earlier cars. Evidently they abolished it in at least some later blocks. There is also a 3rd possible location, on some bell housings, that ends up right behind the one Joe's pic shows the stud in.

Some of you guys might be old enough to remember driving without a Power-Assisted (Hydraulic Slave or Throwout-Bearing) Clutch...
A heavy-duty Pressure-Plate would mean that your left leg muscles were going to end up much larger than your right leg!
It is definitely nice to have a Hydraulic Throwout-Bearing today!
It does not matter how firm that Pressure-Plate is... the Clutch-Pedal feels like butter!
Good bye to the old mechanical-linkage (Z-Bar and all)!
Kids today will never know what it was like to have to kick the ever-loving-**** out of the Clutch-Pedal to shift your hot-rod/ muscle-car!
