Edelbrock Rollin Thunder Camshaft Hydraulic Roller for Mark IV Big-Block Chevy 500+ CI

If you're building a serious street machine or a powerful truck with a big-block Chevy Mark IV or Gen V engine, especially one displacing 500 cubic inches or more, getting the right camshaft is key to unlocking its potential. The Edelbrock Rollin' Thunder Camshaft is designed to give you that strong low-end to mid-range torque you need for daily driving, towing, or just getting off the line in a hurry. It's a hydraulic roller camshaft, which means it's built for durability and performance over the long haul.

This camshaft is engineered to work well with Edelbrock's Performer manifolds, aiming for optimal performance between off-idle and around 5500 RPM. You can expect a noticeable improvement in throttle response and overall torque output, making your vehicle feel much more lively. For those looking at the numbers, when paired with specific Edelbrock components like the Victor Jr. intake and E-CNC cylinder heads, this cam helped achieve an impressive 676 horsepower and 649 ft-lbs of torque in testing. Keep in mind that this camshaft requires a high stall torque converter to perform at its best, and it's not intended for 1965-66 Big Block Chevys that need a grooved rear cam journal.

Included with the camshaft are flat tappet lifters, assembly lube, and installation instructions to help you get it installed correctly. With an intake duration of 248 degrees and an exhaust duration of 256 degrees, along with lifts of .632" intake and .648" exhaust, this cam offers a solid profile for street-driven applications that demand more grunt.
