An internal combustion engine has air/fuel intake manifolding and porting proximate the head of the engine, and exhaust manifolding and porting proximate the head of the engine, the engine including: (a) a cylinder block having two longitudinal rows of cylinders with V-shaped configuration, (b) the block forming coolant passages proximate the cylinders, there being multiple coolant inlets at one side of each of the rows to flow coolant to the passages at said one side of each of the rows and also to flow coolant around opposite ends of each row to the passages at the other side of the row, (c) and a cylinder head for each of the rows of cylinders, each head having first and second coolant passages respectively in communication with the passages in the block at the one and the other side of each such row of cylinders to receive coolant flow therefrom, the second passages in the head extending proximate the air/fuel intake porting, the first passages in the head extending proximate the exhaust porting, said intake manifolding everywhere isolated from the first passages in the head.
