PRODUCT DETAILS:
This direct replacement water pump features cast iron construction with a precision-formed metal impeller designed for the Chevrolet small block 305 and 350 cubic inch V8 engines powering GM trucks vans and Suburbans from 1965 through 1974. The belt-driven standard rotation pump ensures proper factory equivalent installation as a direct replacement for GM original equipment part numbers 3947051 and 3861920. The Chevrolet small block V8 is the most successful engine family in automotive history and during this era the 350 cubic inch version was the go-to powertrain for GM trucks and full-size vehicles. In the C/K series pickups the 350 V8 produced between 250 and 300 horsepower providing ample power for work and recreation. These vintage Chevrolet and GMC trucks are highly sought after by collectors and restorers today. The pump fits a wide range of models including C/K pickups in both two-wheel and four-wheel drive configurations, G-series vans, P-series forward control chassis, and the iconic Suburban. Cast iron housing provides OE-level structural integrity. Features permanently sealed bearings with precision-ground shaft.
