COMP Cams Cam & Lifter Kit CB 283T HR-7

When you're looking to wake up your Chevrolet Big Block engine, this COMP Cams Cam and Lifter Kit CB 283T HR-7 is a solid choice. What you get in this kit is everything you need to get started: the camshaft itself, a set of hydraulic roller lifters, assembly lube to make sure everything goes together smoothly, decals for that custom look, and the installation instructions. This kit is designed for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts, and it's a popular upgrade for a high-performance street setup.

The CB 283T HR-7 camshaft features a 227-degree intake and 241-degree exhaust duration at .050 lift. This grind is known for its choppy, thumping idle, which is a signature sound for performance street engines. While it can work with a stock torque converter, you'll see improved results and a more consistent power band with a 2000+ RPM stall converter and appropriate gearing. This hydraulic roller setup offers better performance and durability compared to traditional flat tappet designs.

This kit is intended for a high-performance street application and is not CARB approved, meaning it cannot be shipped to California. It's a significant upgrade for vehicles like the Chevrolet Impala, Chevelle, or Camaro from the late 60s and early 70s, offering a noticeable change in the engine's character and power delivery.
