Cast Shark Tooth Oil Pump Standard Volume Suit SB Chev, Use 5/8" Press In Screen

Melling has improved the heart-beat of the traditional internal gear pump. It is now significantly smoother through the use of new helical asymmetrical gears. The new gear design provides the engine with an improved flow of oil without the usual pulsing found in traditional gear pumps. The reduction in the pressure ripple from the pump will also provide benefits to the distributor and camshaft drive.

Features:

• High pressure upgrade of the m-55 & m-55a oil pumps
• Exclusive helical asymmetrical gears
• Significant reduction in pressure ripple (pulsing)
• Reduction in torque ripple in the pump drive
• Improved distributor operation - reduction in spark scatter
• Improved distributor gear and intermediate shaft wear
• Includes 12550 chrome-moly intermedia
