Edelbrock Rollin’ Thunder Camshaft # 2281 is designed for 351W Ford V8 engines 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 449HP and 413 Ft Lbs of Torque when paired with RPM Air-Gap Dual Quad intake manifold # 75354 and Performer RPM cylinder heads # 60255. Must use a high stall torque converter. Will not work with stock valve springs.Camshaft specifications:• Intake duration: 235 Degrees • Exhaust duration: 238 Degrees • Intake lift: .573” • Exhaust lift: .582” • Lobe separation: 112 Degree • Intake Center Line: 107 • Vacuum: 10”
