When you're looking to get the most out of your Chevrolet or GMC Big Block Gen VI engine, this complete camshaft kit from COMP Cams is a solid option. You'll receive the XR300HR-14 camshaft itself, along with a full set of hydraulic roller lifters, upgraded valve springs, retainers, valve locks, and valve stem seals. It also includes a new timing chain set to ensure your timing is spot on, plus assembly lube and decals for a professional finish. This kit is designed for engines like the 454 and 502, and it works particularly well with larger cubic inch applications.

This kit is built for performance, featuring an Xtreme Energy grind with a 248/254 degree duration. It’s a popular choice for bracket racing because it offers a noticeable improvement in power and torque. To make the most of this camshaft, it’s recommended to pair it with a torque converter that has a stall speed of 3500 RPM or higher, especially on larger displacement engines. The hydraulic roller design means you get the performance benefits without the maintenance hassle of a flat tappet system.

This kit is designed to fit a range of Chevrolet and GMC trucks and vans from the mid-to-late 90s, including models like the C2500 Suburban, K3500, and Express 3500. It's a comprehensive package that takes the guesswork out of upgrading your camshaft and valvetrain, ensuring all the components are matched for optimal performance and reliability.
