    For high-performance street applications, Performer RPM Camshafts provide power from 1500 to 6500 RPM. These flat-tappet 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
