PERFORMER-PLUS CAMSHAFTS
Designed for optimum torque from the low-end to the mid-range, Performer-Plus 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. 3 our most popular Performer-Plus camshafts for small-block Chevys are 50-state street legal. |

PERFORMER RPM CAMSHAFTS
Designed for street high-performance applications, Performer RPM cams provide power from 1500 to 6500 rpm. These hydraulic lifter camshafts are dyno-matched to Performer RPM manifolds for high-rpm horsepower while still maintaining acceptable low-end torque. With 10 to 12 inches of manifold vacuum at idle, Performer RPM cams have more lift and duration than most street camshafts. In the manifold section you'll find horsepower graphs showing the power levels obtainable when the Performer RPM package is used with the right combination of Edelbrock components. Hydraulic flat tappet lifters are included with each Performer RPM camshaft. |
