Edelbrock Rollin' Thunder camshaft #2263 

Rollin' Thunder Camshaft #2263 is designed for 500+ Mark IV and Gen V engines from 1967-95 and produce optimum torque from the low-end to the mid-range. Rollin' Thunder 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. This cam produced 676HP and 649 Ft Lbs of Torque when paired with Victor Jr. intake manifold #2902 and E-CNC cylinder heads #79555. Not for 1965-66 Big block Chevy's requiring a grooved rear cam journal. Must use with a high stall torque converter.
