Edelbrock Performer-Plus Camshaft #2157 is designed for 350-455 Pontiac V8 engines and produce optimum torque from the low-end to the mid-range. Performer-Plus camshafts should be matched with Performer manifolds for vehicles operating from off-idle to 5500 rpm. The Performer-Plus #2157 is a smooth idling cam 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 387HP and 439 Ft Lbs of Torque when paired with Performer intake manifold #2156 and Performer RPM cylinder heads #60599. Camshaft specifications: - Intake duration: 204 Degrees - Exhaust duration: 214 Degrees - Intake lift: .420" - Exhaust lift: .442" - Lobe separation: 110 Degree - Intake Center Line: 105 Degree - Vacuum: 15"
