A V-shaped cylinder block for a V-type engine includes a main oil gallery elongating in an axial direction of a crank shaft; a subordinate oil gallery elongating in the axial direction thereof; a linkage passage interconnecting the main oil gallery to the subordinate oil gallery; a first feed passage feeding oil from the subordinate oil gallery to a predetermined crank journaling portion disposed at least on one side of the cylinder block in the axial direction thereof without passing through the main oil gallery; a second feed passage feeding a lubricating oil from the main oil gallery to the crank journaling portions other than the predetermined crank journaling portion; and a pump chamber having a rotary shaft disposed in parallel to the crank shaft. The main oil gallery disposed in a middle portion between the left-hand and the right-hand banks and at a position above the crank chamber, the main oil gallery being in a length elongating in the axial direction thereof and failing to reach the predetermined crank journaling portion. The subordinate oil gallery is disposed on an outer side portion of the left-hand and right-hand banks. The pump chamber is disposed at one end portion of the cylinder block in the axial direction thereof and formed on an imaginary line extending from the main oil gallery.
