Part Number: 7157

ALL  CAMSHAFT KIT - Part Number 7157
Camshaft Kit Performer RPM. Pontiac 350-455 V8. Performer-Plus Cam Kit. Designed for street high-performance applications. Performer RPM cams provide from 1500 to 6500 rpm. These hydraulic lifter camshafts are dyno-matched to Performer RPM manifolds for high-rpm horsepower while 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 engine components. Important Application Information: Performer RPM, Performer RPM Hydraulic Roller and Torker-Plus cams are for street high-performance and racing applications only - not for heavy vehicles. Use with Edelbrock Performer RPM heads (or other aftermarket heads), adjustable valvetrain components, screw-in studs, high-performance adjustable rocker arms and at least 9.5:1 compression ratio. Headers, high-energy ignitions, lower-than-stock rear gearing and a high-performance torque converter (in auto transmission equipped vehicles) are necessary. Important Notes: Our cam warranty will be honored only if the recommended Edelbrock Sure Seat Valve Springs are used. If a warranty problem does arise, the end flap or label from the Edelbrock Sure Seat Valve spring box along with store receipt must be sent with warranty claim. When changing your cam, it's essential to change your timing chain. We recommend Performer-Link Tru-Roller Timing Sets or Accu-Drive Cam Gear Drives.
