Keep oil moving under demanding RPM conditions with the Melling Performance oil pump 10050ST-825SS, a high-volume, high-performance billet pump built for GM small-block V8 applications. It draws oil from the pan and pressurizes it to feed the engine's oil galleries, moving about 25% more volume than a stock pump for street and strip use. It fits hundreds of GM V8s, including the 1988-1999 Chevrolet C1500 and K1500 and the Chevrolet Impala — see the Buyer's Guide tab for the full list.
Designed for street, strip and racing use with 8 1/4 inch deep oil pans.
