    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 many GM V8 vehicles, including the 1988-1999 Chevrolet C1500 5.7L, the 1988-1999 Chevrolet K1500 5.7L and the 1958-1985 Chevrolet Impala 4.4L / 4.6L / 5.0L / 5.3L / 5.4L / 5.7L / 6.6L — see the "Vehicles it fits" section for the full list.

    • Billet construction: 6061-T6 billet aluminum housing and billet aluminum cover with a durable anodized hardcoat, plus billet steel "Shark Tooth" helical gears, CNC machined to exacting tolerances.
    • Adjustable pressure: manufactured at 70 PSI (Red spring) with included alternate springs for 60 PSI (Pink) and 80 PSI (Orange), plus adjustable bypass pressure.
    • Extra shaft support: chromoly steel drive shaft with the pump shafts extended into the cover; a 12550 chromoly intermediate shaft is included.
    • Integrated pickup: a supercharged inlet designed for improved high-RPM performance and an integrated stainless steel wire-mesh pickup screen, 1.650 in (40 mm), that draws oil from the pan.

    Designed for street, strip and racing use with 8 1/4 inch deep oil pans. Gaskets, seals and mounting hardware are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Each pump is individually pressure- and flow-tested. Made in the United States.
