Edelbrock Rollin' Thunder camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide excellent vacuum at idle to support power accessories. Rollin' Thunder camshafts feature more aggressive lift profiles than possible with conventional flat-tappet hydraulic cams, without excessive valve overlap that can compromise low rpm drivability; reduced friction provided by roller tappets makes this combination of accelerated valve lift and reduced duration possible. Edelbrock Rollin' Thunder camshafts are performance matched to Edelbrock Total Power Package components for proven performance.
