A good oil pump is the cheapest insurance you can buy. Milodon small block Chevy high/standard volume oil pumps were built with engineering expertise to provide the highest level of quality and reliability available. The improved housing is made of a G-10 material with 40,000 psi tensile strength. G-10 is the same rugged material that brake rotors are made of. The neck is thicker than standard pumps to improve strength and end pump neck breakage under severe conditions. They're engineered to perform well in low or high-rpm applications and are CNC-machined for precise tolerances. Every pump is 100 percent flow-tested.
