Chevy Big Blocks have two different "routings" for the coolant flow. Most but not all Mark IV big blocks use series flow. The coolant from the radiator enters the water pump and is forced into the front of the block. It travels to the rear of the block to a pair of passages in the block deck, head gasket, and cylinder head.
