Details

Our 100% new, pressure cast & CNC machined pumps feature characteristics often overlooked by other manufacturers - precision-ground hubs to eliminate vibration; heavy duty ball-roller or ball-ball bearings; ceramic seal assemblies for extended life; closed-vane impellers for unsurpassed output; and zinc-coated backplates to stand up to corrosion.

"Short" style pumps came on all factory small block V8s from 1955 to 1968. However, this pump will fit all S/B Chevys up to 1985.

NOTE: This pump is designed primarily for street use and should not exceed 5,500 RPM.
