The Melling SBC Pump 3/4 Opening (M155HV) is a high-volume wet sump oil pump designed for small-block Chevrolet engines, suitable for both street and performance applications. This pump is essential for builders looking to upgrade their oiling systems, particularly when increasing engine displacement, boost, or operating temperatures.
Engineered with optimized internal gear geometry, this pump delivers consistent pressure and volume across the RPM range, effectively preventing oil starvation during high-load operation. The wet sump design circulates oil from the pan through the block and cylinder head passages, ensuring cooling and lubrication of critical bearing surfaces. Constructed from durable cast iron, it provides thermal stability and reliability under demanding conditions.
The Melling M155HV is ideal for street performance builds, bracket racing engines, and mild forced-induction setups where stock oiling architecture may be inadequate. Before installation, confirm your block's inlet opening diameter (3/4 inch) and pump drive configuration to ensure compatibility with your engine setup.
