What is the main benefit of the patented orifice metering valve?

The patented orifice metering valve precisely meters oil to the rocker arms. This prevents excessive oiling at high RPMs while ensuring continuous contact, which helps maintain consistent lubrication and engine performance.

What material is the pushrod seat made from and why is it important?

The pushrod seat is constructed from a special powdered metal iron alloy. This material is heat-treated for enhanced strength and wear resistance, contributing to the overall durability and longevity of the lifter.

Are these lifters suitable for all International Harvester V8 engines?

This specific set is designed for International Harvester V8 engines with displacements of 266-392 cubic inches. It's important to verify fitment for your specific year and model, as applications can vary.

Product Details

When you're rebuilding the top end of your International Harvester V8, like the 266 or 392 cubic inch engines, you need reliable hydraulic lifters. This set from COMP Cams includes 16 High Energy Hydraulic Flat Tappet Lifters, designed to ensure proper oil flow and consistent performance.

What sets these lifters apart is their patented orifice metering valve. This feature precisely controls the amount of oil sent to the rocker arms, preventing excessive oiling at higher RPMs while maintaining continuous contact. The pushrod seat is made from a heat-treated powdered metal iron alloy, giving it extra strength and wear resistance for the long haul. Plus, the longer piston design offers a larger load-bearing surface, which helps increase the lifter's lifespan. The lightweight check valve disc inside allows for quicker response, meaning your engine can reach higher speeds before the valves start to float, giving you more control across all engine speeds and loads.

This set is a solid option for International Harvester V8 engines from the early 70s through the late 70s, including models like the Scout II and various International trucks. They are built to last and help your engine perform at its best.
