Product Details
This COMP Cams CRB3 283R-8 solid roller camshaft is built with a 3-bolt design, fitting Chrysler B/RB engines like the 383, 400, 413, 426 Wedge, and 440. It's specifically tuned to generate super strong low-end torque, making it a great choice for drag racing applications where getting off the line quickly is critical.
For optimal performance with this camshaft, COMP Cams recommends pairing it with a 10.5:1 compression ratio and a single plane intake manifold. This setup helps maximize the powerband and leverage the camshaft's torque-producing capabilities. You'll also want to ensure you have a 3500+ RPM stall torque converter for automatic transmissions – specifically, a 3500+ stall for a 440 engine and around 3800 for a 383. Because this is a solid roller camshaft, you will need to upgrade your distributor gear to a compatible material, typically bronze, to prevent premature wear.
This camshaft is designed for serious performance builds, particularly those focused on drag racing. While it offers impressive low-end grunt, remember that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup, including the necessary distributor gear upgrade and any other required components for your specific engine build.
