Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.
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
