COMP Cams Pro-Mag Lifters Olds260-455/P

COMP Cams is well-known for performance engine components, and these Pro Magnum hydraulic lifters are a prime example of their work. If you're building or rebuilding an Oldsmobile 260-455 or Pontiac 326-455 V8, these lifters are designed to help you get the most out of your engine, especially at higher RPMs. They are specifically engineered to prevent the harmful "pumping up" that can occur when an engine is running fast, ensuring more consistent valve train operation.

What sets these lifters apart is their unique design, which yields a notable power increase compared to standard hydraulic lifters. They feature a .842-inch diameter and a seat height of 2.01 inches, with a weight of 96 grams each. For proper installation and function, an adjustable valve train is required, and the pre-load should be set between .002" and .004" with the engine warm. These lifters fit a wide range of vehicles, including models like the Oldsmobile Cutlass Supreme, Buick LeSabre, and Pontiac Firebird.
