Edelbrock RPM Hydraulic Roller Cam Only 283-400 Chevy 57-86

With this Edelbrock Rollin' Thunder camshaft, you're getting a complete package designed to wake up your Chevy V8. Inside the box, you'll find the camshaft itself, a set of flat tappet lifters (since this isn't designed for stock roller lifters), assembly lube to help with installation, and detailed instructions to guide you through the process. This camshaft is built for a wide range of Chevrolet and other GM vehicles from 1957 through 1986, specifically targeting the 283, 305, 350, and 400 cubic inch small-block V8 engines. It's a popular choice for daily drivers, trucks, and RVs that need more grunt from off-idle up to about 5500 RPM.

The engineers at Edelbrock designed this cam to deliver a noticeable improvement in throttle response and torque, making your vehicle feel more responsive when you step on the gas. With an intake duration of 234 degrees and exhaust duration of 238 degrees, along with .539 inches of intake lift and .548 inches of exhaust lift, it's tuned for strong low-end and mid-range power. When paired with specific components like the Performer RPM Air-Gap intake manifold, a Thunder Series AVS carburetor, and Performer RPM E-Tec cylinder heads, this camshaft helped achieve an impressive 435 horsepower and 435 ft-lbs of torque in testing. For optimal performance and longevity, it's important to use it with a thrust button, a high stall torque converter, and stock ratio rocker arms only.

This camshaft is a solid option for anyone looking to add more usable power to their classic Chevy V8. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding setup and compatibility requirements.
