4 bolt block oiling Question for my 3rd Gen
I am building a 4bolt truck roller block for my 92' Z. In the manual I am using it shows a plunger plug that goes in the oil passage under the oil pump. I realize the engines used in this book might not 87' and newer engines but I have not found any reference in Haynes or Chilton to this plug.
Do I need one?? The block is a 638 casting.
