In the never ending quest to save weight and keep cool we use an Edelbrock aluminum water pump when a replacement is called for. The Edelbrock pump is good at cooling and is flow bench tested for balanced flow and maximum cooling capacity.
Of course, its aluminum construction saves weight over that cast iron pump, and every little bit helps. An Edelbrock aluminum water pump for your small block Ford costs $159.95. Contact Edelbrock at (310) 781-2222 www.edelbrock.com
