Official Release:

Edelbrock is excited to offer a new Rollin’ Thunder camshaft for small-block Chevrolet engines.
Edelbrock Rollin’ Thunder camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide sufficient vacuum. Rollin’ Thunder camshafts feature more aggressive lift profiles than conventional flat-tappet hydraulic cams, without excessive valve overlap that can compromise low rpm drivability.

The new Rollin’ Thunder camshaft (#2231) is designed specifically for use with 1957-86 Chevrolet 283-400 V8 engines. This camshaft features a unique profile that will provide sufficient vacuum at idle for power brakes and other vacuum powered accessories. This camshaft includes assembly lube and instructions (lifters sold separately). In testing, this camshaft produced 460 HP and 460 ft-lbs. of torque when matched with a Performer RPM intake manifold (#7516), Thunder Series AVS carburetor (#1813) and Performer RPM E-Tec cylinder heads (#60985) on an Edelbrock 383 crate engine.
