58-78 Big Block Chrys. Oil Pump

The MELLING 58-78 Big Block Chrysler Oil Pump (M-63HV) is designed for owners and builders working with classic and muscle car big-block engines from Chrysler's golden era. This pump is essential for reliable lubrication in high-displacement powerplants, ensuring consistent oil delivery under demanding conditions.

Engineered with Melling's precision gear pump design, the M-63HV features optimized gearing that maximizes flow rate across the RPM range typical of naturally aspirated big-block applications. Its internal geometry balances pressure relief dynamics with volume delivery, preventing starvation at idle while managing pressure spikes during operation.

Mechanics and engine builders favoring proven OEM-specification components will recognize the M-63HV as a reliable choice for any 58–78 big-block Chrysler project. While it is compatible with factory oiling systems, users should verify compatibility with specific performance modifications to ensure optimal performance.
