Melling M Select Series Oil Pump For Ford 351 Windsor Engines. High volume performance upgrade for M-83. Gerotor set assembled to an extended drive shaft that allows for additional support in the cover. Supporting the drive shaft in both the housing and cover eliminates dynamic shaft deflection at increased RPM levels.
The cover is doweled to the pump housing to assure alignment of shaft bores. The housing and cover are CNC machined and phosphate coated for wear and rust prevention. The relief valve has a pressure adjustable screw-in plug instead of a cup plug. Use The Compatibility Guide to Find Your Application. Or Message Us With Any Fitment Questions.
