An internal-combustion engine includes an engine block, a plurality of parallel cylinders and oil chambers defined in the engine block; intake valves, exhaust valves, overhead valve controls and crankshaft bearings supported in the engine block as well as a pump supported in the engine block for delivering oil through the oil chambers for cooling the engine. The engine block is a single-piece cast component in which the oil chambers extend adjacent and parallel to the cylinders and are accessible from opposite sides of the engine block where the crankshaft bearings and the valve controls are supported.
