Hi-Flo aluminum water pump for the 1963, 1964, and 1965 Ford equipped with a small block engine.
For cars originally equipped with a factory aluminum water pump including K code cars.
Helps resolve low-speed heating problems by doubling flow rates at low rpm and when idling.
Unique features such as larger impeller diameters, increased vane count, tighter clearances, shrouding and porting allow this to help drop engine temperatures up to 30 degrees.
Helps increase the block pressure to prevent hot spots on cylinder walls and stops the formation of steam pockets in the block all while delaying the onset of cavitation at higher rpm.
