Edelbrock Rollin' Thunder Camshaft #2216 is designed for LS1/LS6 Gen III Chevy's from 1997-04 and produces optimum torque from the low-end to the mid-range. Rollin' Thunder camshafts should be matched 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. This cam produced 460HP and 424 Ft Lbs of Torque when paired with Performer RPM Intake manifold #71187, Thunder Series AVS Carb #1813 and E-CNC 215 cylinder heads #79949. Use with high stall torque converter only.
