Oil Pump - Ford 390-428

The MELLING Oil Pump M-57HP is a high-pressure wet sump pump engineered for Ford FE-Series engines, including 390 and 428 cubic inch displacement blocks. This internal pump delivers the elevated oil pressure and volume demand of classic big-block Ford engines, ensuring reliable lubrication during sustained operation across street, strip, and marine applications. Built to OEM specifications, the M-57HP maintains consistent flow rates essential for protecting main bearings, rod journals, and cam drive systems under load.

The pump's high-pressure calibration addresses the cooling and bearing clearance requirements of the FE-Series architecture. Weighing 3.95 lbs with compact dimensions of 5.1 x 4.3 x 5.9 inches, the M-57HP integrates directly into existing wet sump system configurations without requiring external modifications. Standard volume output matches factory-intended flow rates, preventing starved galleries while avoiding excessive system pressure that can damage seals and gaskets. Proper oil pump selection is critical for engine longevity—undersized or worn pumps reduce film strength at high RPM and elevated temperatures.

Operators rebuilding or restoring 390 and 428 FE-Series engines—whether for vintage muscle car restoration, marine propulsion platforms, or performance street applications—depend on OEM-specification pumps to maintain baseline reliability. The M-57HP pairs with stock or lightly modified engine builds where wet sump systems are retained. This pump is not compatible with dry sump conversions. Buyers should confirm their specific FE-Series engine displacement and sump configuration before installation.
