E2261 - 1965-90 Chevrolet 396-502 Big Block Rollin' Thunder Hydraulic Roller Camshaft
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.
