What type of valvetrain is required for this camshaft?

This is a solid roller camshaft, which means it requires a compatible solid roller lifter set, roller rocker arms, and appropriate valve springs. These components are necessary to handle the cam's aggressive profile and ensure proper operation and durability.

What compression ratio and stall speed are recommended for this camshaft?

For optimal performance, this camshaft is recommended for use with a 12:1 compression ratio. It also pairs best with a torque converter that has a stall speed of 5500 RPM or higher to effectively utilize the cam's power band.

Can this camshaft be used in a street-driven vehicle?

While designed for racing applications like super gas and bracket racing, this camshaft can be used in heavily modified street-driven vehicles. However, it requires a robust valvetrain and is best suited for engines built for high performance, not necessarily for daily commuting.

Product Details

This COMP Cams Rx308R-8 camshaft is a solid roller type, specifically designed for Chrysler 273, 318, 340, and 360 cubic inch LA engines. It's built for performance applications, particularly suited for super gas or fast bracket racing where quick response and strong power delivery are key. To get the most out of this camshaft, it's recommended for use with a 12:1 compression ratio and a stall speed of 5500 RPM or higher, ensuring it can effectively utilize the cam's aggressive profile.

The camshaft features a 275-degree intake duration and 284-degree exhaust duration, with a 112-degree lobe separation angle. These specifications contribute to its aggressive nature, providing improved airflow and power output, especially at higher RPMs. As a solid roller camshaft, it requires a compatible valvetrain setup, including roller lifters, roller rocker arms, and appropriate valve springs to handle the increased lift and duration. This setup is crucial for achieving optimal performance and durability.

This camshaft is a popular choice for drag racing enthusiasts looking to extract maximum performance from their Mopar LA engine. While it's designed for racing, it can also be a solid option for street-driven vehicles that have been heavily modified for performance. Please note that this camshaft is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation instructions for proper setup and compatibility with your specific engine build.
