A cylinder block assembly (300) for an X-engine includes a first block half (302) having two cylinder banks (453, 454) and valley openings (361, 362) between the two cylinder banks (453, 454); and a second block half (304) fastened to the first block half (302), the second block half (304) having two cylinder banks (451, 452) and valley openings (361, 362) between the two cylinder banks (451, 452). The valley openings (361, 362) in the first and second block halves (302, 304) allow an X-engine crank train assembly (10, 100) to be assembled within the cylinder block assembly (300).
