Now available from Ames Performance Engineering: 1969 Pontiac V8 4” (SHORT) hub water pumps. These transitional water pumps were used on early production 1969 models only. Each pump is manufactured with OEM markings and large vein cast iron impellers like originals. Cast impellers are imperative for optimal cooling-unlike stamped steel impellers, cast iron parts eliminate unwanted deflection and eliminate the potential for cavitation in the timing cover body.
