COMP Cams Camshaft Kit CS 252XFI HR-13

COMP Cams is well-known for performance valvetrain components, and this SK-Kit is a prime example of their expertise for Chevrolet Small Block engines. If you're looking to get more out of your 305 or 350 TBI engine, this kit is designed to deliver extreme torque and excellent performance right off idle. It's a comprehensive package that includes the camshaft, lifters, a timing chain set, assembly lube, decals, and instructions, so you have the essential parts to get the job done.

This kit features the CS 252XFI HR-13 camshaft, which is a hydraulic roller design. This type of camshaft generally offers improved durability and less friction compared to flat tappet designs. The specific grind, with intake and exhaust durations of 202 and 212 degrees respectively, is tuned for strong low-end torque, making it ideal for applications where you need immediate response from a standstill, like in many trucks and older muscle cars. It's built to work with Chevrolet GEN 1 Small Blocks, covering a wide range of displacements from 262 up to 400 cubic inches.

It's important to verify your engine's setup before installation. This kit is intended for engines that originally used a flat tappet camshaft. While GM began phasing in roller camshafts in the mid-80s, many trucks and SUVs continued with flat tappet designs well into the 90s. You'll need to remove the intake manifold or timing cover to confirm if your block is factory-equipped for a roller camshaft. For 1955-1957 Chevrolet 265 engines, ensure there's a groove on the 5th cam journal for proper oiling; contact COMP Cams for details if yours lacks it. This kit fits a wide variety of vehicles, including models like the Chevrolet C10, Buick Roadmaster, and AM General Hummer, among many others.
