What other components are typically needed when installing this solid roller camshaft?

Installing a solid roller camshaft usually requires a complete compatible valvetrain. This includes solid roller lifters, roller rocker arms, and potentially upgraded valve springs and pushrods to handle the increased lift and operating speeds. It's recommended to consult COMP Cams' specific installation guidelines for this camshaft.

Is this camshaft suitable for daily driving or street use?

This camshaft, the CB 316Fr-12, is specifically designed as a Drag Race camshaft. Its aggressive duration and lift profile are optimized for high-RPM power on the track and may result in rough idling, poor low-end torque, and reduced drivability on the street. It is best suited for dedicated drag racing applications.

What is the significance of the 112-degree lobe separation angle?

A 112-degree lobe separation angle (LSA) typically results in a broader powerband and a slightly rougher idle compared to cams with wider LSA. For this drag race camshaft, it helps to create a strong power curve that comes on strong in the upper RPM range, which is crucial for acceleration down the drag strip.

Product Details

If you're building a serious drag racing machine based on a Chevrolet Big Block engine, this COMP Cams CB 316Fr-12 Drag Race camshaft is designed to help you achieve your goals. This solid roller camshaft is specifically intended for Chevrolet 396, 427, 454, and similar displacement Big Block engines that originally came with flat tappet camshafts. It features a 282-degree intake duration and a 298-degree exhaust duration, with a 112-degree lobe separation angle, optimized for high-RPM power delivery on the drag strip.

This camshaft is a well-built component featuring a solid roller design, which allows for more aggressive lobe profiles and higher valve lift compared to flat tappet designs. This translates to better cylinder filling and more efficient combustion at high engine speeds. The specific grind, CB 316Fr-12, is a popular choice for racers looking to extract maximum horsepower from their Big Block Chevy. It's important to note that installing a solid roller camshaft often requires compatible roller lifters, roller rocker arms, and potentially upgraded valve springs to handle the increased lift and operating speeds. Ensure your valvetrain components are up to the task to get the most out of this camshaft and maintain reliability.

This camshaft fits a wide range of Chevrolet vehicles, including popular models like the Chevelle, Impala, and C10 pickup trucks from the late 1960s through the mid-1970s, as well as later model C/K series trucks and SUVs. Because this is a performance camshaft intended for racing applications, it is not CARB approved and cannot be shipped to California. Always consult the manufacturer's detailed installation instructions for proper setup and valvetrain requirements to ensure optimal performance and longevity.
