Premium standard rotation aluminum water pump for 1970-78 5.0L and 1970-87 351W engines. The Maximum Flow pumps feature heavy-duty ball/roller bearings for long life, a CNC-machined curved vane impeller and billet hub, and distribute the same amount of coolant to both sides of the engine block. That eliminates hot spots, to help your engine produce maximum power without detonation or pre-ignition problems.
