Edelbrock Rollin’ Thunder Camshaft for ’57-’86 SB Chevy

Edelbrock Rollin’ Thunder series camshafts improve horsepower and torque, produce a satisfying performance idle, and provide sufficient vacuum for power brakes and other powered accessories. As with all Rollin’ Thunder camshafts, the 2231 features a more aggressive lift profile than conventional hydraulic flat-tappet cams—without the excessive valve overlap that can compromise low-rpm drivability.


  • Exclusively engineered for 1957–1986 Chevy V8 engines.
  • Designed for optimum power from 1500 to 6500 rpm.
  • Produced 460 hp and 460 ft-lb. torque on an Edelbrock 383 crate engine.

  • 242° intake / 240° exhaust duration at .050?, .594? lift at valve, and 112° lobe separation.
