Evans - Designed Chevy Coolant Pumps
Small block and big block Chevy racing pumps are manufactured by Evans. They feature 356-T6 aluminum heat treated housings and Evans CAD CAM designed 8-vane 4.4” O.D. high efficiency impeller, which is capable of the highest gallon per minute flow rate in the industry. The pump eye and inlet cross section have been increased by 20% for decreased draw restriction. Extra material is added for external lines and the housing has been machined to accept a Viton O-ring for a positive seal with the back cover.
