COMP Cams Lifters SBC Retro-Fit Hydraulic Roller

What you get in this kit is a set of 12 COMP Cams Retro-Fit Hydraulic Roller Lifters. These are designed specifically for early model Small Block Chevrolet engines that originally came with flat tappet camshafts. This upgrade lets you take advantage of the benefits of a hydraulic roller setup, like improved durability and performance potential, without needing to machine your block for a factory roller cam.

These lifters feature a short travel design. This is important because at higher engine speeds, standard hydraulic lifters can sometimes pump up too much, causing the internal piston to move improperly. When this happens, the valves might not close fully, leading to a loss of power and potentially serious engine damage. The short travel design minimizes this internal piston movement, allowing your engine to safely rev higher and perform better when you're pushing it hard.

The tall body construction means these lifters will fit both standard blocks and aftermarket blocks that have a tall lifter bore. This makes them a versatile option for a wide range of Small Block Chevy builds, from 265ci all the way up to 400ci, and many performance variants like the 350, 383, and 427. If you're rebuilding an early small block and want to upgrade to a more efficient and higher-revving valvetrain, these lifters are a solid choice.
