Edelbrock Rollin' Thunder Camshaft #2212 is designed for 426-572 Chrysler HEMI V8 engines and produce 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 705HP and 623 Ft Lbs of Torque when paired with our Dual-Quad intake manifold #7524 Victor Jr. cylinder heads #61175 on a 528 c.i.d. engine. Our #2212 cam utilizes a three bolt configuration. Must use a high stall torque converter only. Camshaft specifications: - Intake duration: 262 Degrees - Exhaust duration: 266 Degrees - Intake lift: .628" - Exhaust lift: .608" - Lobe separation: 114 Degree - Intake Center Line: 109 Degree - Vacuum: N/A
