The Edelbrock 7157 Performer RPM Camshaft Kit is engineered specifically for Pontiac 350-455 V8 engines, delivering exceptional high-RPM performance while maintaining strong low-end torque. This hydraulic flat tappet camshaft is dyno-matched to work seamlessly with Performer RPM intake manifolds, making it an ideal choice for serious street performance applications.

Performance Results:

When tested on a 455 cubic inch Pontiac engine equipped with Edelbrock #7156 intake manifold and #60599 cylinder heads, this camshaft produced an impressive 422 horsepower and 441 ft-lbs of torque. The cam delivers a broad power band from 1,500 to 6,500 RPM, providing excellent drivability with strong top-end performance.

Camshaft Specifications:

• Duration at .050" Lift (Intake): 231 degrees
• Duration at .050" Lift (Exhaust): 240 degrees
• Valve Lift (Intake): .470"
• Valve Lift (Exhaust): .470"
• Lobe Separation Angle: 113.5 degrees
• Intake Centerline: 112 degrees
• Idle Vacuum at 1,000 RPM: 10 inches Hg

Kit Includes:

This complete camshaft kit includes hydraulic flat tappet lifters, providing everything needed for installation. The camshaft features more lift and duration than typical street camshafts, while maintaining 10-12 inches of manifold vacuum at idle for acceptable street manners.
