Edelbrock Rollin' Thunder Camshaft; Hydraulic Roller For 1991 & Later Gen V
Rollin' Thunder camshaft #2264 is designed for optimum torque from the low-end to the mid-range, Performer-Plus camshafts match with Performer manifolds for vehicles operating from off-idle to 5500 rpm. They are smooth idling cams for daily drivers, trucks, vans, RVs and 4x4s. You can expect a major improvement in throttle response and torque. In the manifold section you'll find torque graphs showing the power gains from Performer manifolds and Performer-Plus cams. All camshafts include flat tappet lifters (except for cams designed for use with stock roller lifters), assembly lube and instructions.
