Abstract: An engine block assembly and method manufacturing an engine block assembly and related components. A casted engine block assembly includes a cylinder block portion. The cylinder block portion includes a plurality of cylinder block openings disposed therein, a cylinder block flange portion positioned at a top of the cylinder block portion and a cylinder block crankcase portion disposed at a base of the cylinder block. The cylinder block flange portion is configured for coupling the cylinder block to a cylinder head. The cylinder block portion includes a plurality of cylinder block walls extending between the cylinder block flange portion and the cylinder block crankcase portion and positioned about the plurality of cylinder block openings. The cylinder block walls house a plurality of internal channels. The plurality of cylinder block walls are void of enclosed openings extending through at least one of the cylinder block walls in the plurality of cylinder block walls.
