For street high-performance applications, Performer RPM camshafts provide power from 1500 to 6500 RPM. These hydraulic lifter cams are dyno matched to Edelbrock's Performer RPM manifolds for high-rpm horsepower while maintaining acceptable low-end torque. With 10-12 inches of manifold vacuum at idle, these cams have more lift and duration than most street cams.
*Lifters included
