THE new Chevrolet engine offers, the authors say, the smallest and lightest commercial V-8 power package for its 265-cu-in. displacement. This has been accomplished by an 0.8/1 stroke/ bore ratio, and by weight economies throughout the engine which add up to an assembly lighter by 41 lb than the Chevrolet Six.
New also are its cylinder block casting method, which uses only nine major and three minor cores; its valve-operating mechanism, which features completely independent rocker arms; a lubrication system with short, clean oil passages drilled in the block, none in the cylinder head; and a single intake manifold casting that also forms the top enclosure of the engine and includes provision for hot water heater take-off, cross-over for exhaust heat to the carburetor, distributor mounting, oil filler, thermostat housing, water outlet to the radiator, and water temperature gage hole.
