Based on owner feedback and the spec sheets, the cast iron construction and hardened steel gears provide adequate durability for street and occasional track use. We found it to be a popular choice among Ford enthusiasts looking to improve oil flow without breaking the bank, and the inclusion of a gasket and pickup tube simplifies installation.
However, some users noted that the oil pressure can fluctuate at idle, especially in engines with higher mileage. This may be due to the standard pressure relief spring not being matched to the volume increase. For a daily driver or mild performance build, the value is excellent; but for a race-only engine where consistent high-RPM pressure is critical, a more premium pump with adjustable relief may be a better investment.
- Cast iron body with hardened steel gears
- Direct fit for many Ford small blocks
- Includes gasket and pickup tube
Pros: Affordable price for the volume increase; Good compatibility with Ford small blocks

- Direct replacement for 2V and 3V modular engines
- Includes O-ring and gasket
Pros: Specifically designed for Ford modular engines; Good volume increase for boosted applications
Cons: Limited to Ford modular family
6. Melling M156HV High Volume Oil Pump: For AMC/Jeep
The Melling M156HV is one of the few high volume oil pumps available for AMC V8 engines (360, 401, etc.). We researched its specifications and found it offers a 25% volume increase, which can be beneficial for high-RPM or high-mileage AMC engines. Owner feedback is sparse but generally positive, noting improved oil pressure at idle and better flow at speed. The cast iron housing and hardened gears are standard for Melling, and the inclusion of a pickup tube and screen simplifies installation.
However, due to the niche application, availability can be inconsistent, and some owners have reported difficulty sourcing the correct pickup tube for specific oil pans. Additionally, the standard pressure relief may not be ideal for all builds, and the limited feedback makes it harder to gauge long-term reliability. We recommend this pump for AMC enthusiasts who need increased volume; for other engine families, there are better-documented options.

Frequently Asked Questions
What is a high volume oil pump and when is it needed?
A high volume oil pump moves more oil per revolution than a standard pump, increasing oil flow through the engine. It is typically needed in high-performance engines that operate at high RPMs, engines with increased bearing clearances, or when using oil coolers or remote filters that add restriction. However, for a stock engine, a high volume pump can cause excessive oil pressure, leading to oil foaming, filter bypass, or gasket leaks.
Will a high volume oil pump increase oil pressure?
Not necessarily. High volume pumps are designed to increase flow, not pressure. However, because they move more oil, they can cause higher pressure if the engine’s oiling system cannot pass the extra volume. Many high volume pumps include a standard pressure relief spring to limit pressure. It’s important to match the pump to your engine’s requirements; some builds may need a high-pressure spring as well.
Can a high volume oil pump damage my engine?
Yes, if improperly matched. Excessive oil pressure can blow out oil filters, damage gaskets, or cause oil foaming. Additionally, the extra load on the camshaft and distributor gear can accelerate wear. Always ensure the pump’s volume and pressure ratings are appropriate for your engine’s clearances and intended use. Consulting with an engine builder is recommended.
Do I need to modify my oil pan for a high volume pump?
Often, yes. High volume pumps may have a larger body or require a deeper pickup tube. Some oil pans have baffles that interfere with the pump. Many manufacturers specify pan modifications or recommend specific pans. Check the pump’s installation instructions and measure clearance before assembly.
What is the difference between high volume and high pressure oil pumps?
High volume pumps increase oil flow (gallons per minute) while high pressure pumps increase the maximum oil pressure (psi). Some pumps combine both features. High volume is better for high-RPM engines that need to maintain oil film, while high pressure is useful for engines with loose bearing clearances. Using both can lead to excessive pressure if not carefully controlled.
