COMP Cams Hydraulic Lifters Chevy SB/BB

COMP Cams is well-known for making performance valvetrain components, and these High Energy Hydraulic Flat Tappet Lifters are a solid choice for your Chevrolet Small Block or Big Block engine build. They're designed to precisely meter oil to your rocker arms using a patented orifice metering valve, which helps prevent excessive oiling at higher RPMs. This continuous contact between the metering valve and the pushrod seat is key to their reliable operation.

The pushrod seat itself is made from a heat-treated powdered metal iron alloy, giving it strength and wear resistance for longer life. You'll also find these lifters have a longer piston than conventional ones, which means more surface area for load bearing and ultimately, increased longevity. The lightweight check valve disc inside allows for quicker response, helping your engine reach higher speeds before experiencing valve float, and it maintains added control across all engine speeds and loads.

These lifters fit a wide range of Chevrolet engines, including popular Small Blocks like the 262 through 400 V8s, and Big Blocks like the 348, 409, 427, and 454. They are a popular choice for many Chevrolet applications from the late 1950s through the late 1990s.
