Edelbrock has introduced new Rollin’ Thunder camshafts 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. In testing, this camshaft produced 460 HP and 460 ft-lbs. of torque when matched with one of Edelbrock’s Performer RPM intake manifolds (#7516), Thunder Series AVS carburetor (#1813) and Performer RPM E-Tec cylinder heads (#60985) on an Edelbrock 383 crate engine.
Rollin’ Thunder camshafts are designed for optimum power from 1,500 to 6,500 rpm
