Olds/Pont. V8 Pro-Magnum Hyd. Lifters

The Olds/Pont. V8 Pro-Magnum Hydraulic Lifters by COMP CAMS are designed for builders seeking reliable valve train performance specifically for Oldsmobile and Pontiac big-block platforms. These lifters are ideal for restoring classic muscle cars, upgrading performance engines, or building street machines from scratch.

Featuring precision-engineered internal check valves and plunger assemblies, these hydraulic lifters maintain consistent oil pressure and reduce valvetrain noise during cold starts and idle conditions. Their hardened steel construction and tight tolerances ensure minimal wear over thousands of miles, while the automatic hydraulic compensation adjusts for thermal expansion without requiring manual lash adjustment.

These lifters are particularly beneficial for engine builders working with specific Oldsmobile models such as the 455, 403, and 400, as well as Pontiac 455 and 400 big-blocks. The design enhances valve control, which is crucial for maximizing horsepower and engine longevity in high-performance applications.
