Chevy 396-502ci Big Block V8
Designed for street 396-502ci Chevy V8s with large oval-port cylinder heads (1975 & earlier). This manifold offers the latest technology in dual-plane high rise design and builds outstanding horsepower while maintaining good torque and driveability. No provisions for exhaust heated chokes. Accepts late-model waterneck, air-conditioning, alternator and HEI equipment. Will not fit under stock hood of Corvette, 1965-67 Chevelle, or 1967-81 Camaro.
Designed for street high-performance applications, Performer RPM cams provide power 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.
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 cylinder heads), adjustable valvetrain components, screw-in studs, high-performance adjustable rocker arms and at least 9.5:1 compression ratio. Headers, high-energy ignition, lower-than-stock rear gearing and a high-performance torque converter are necessary.
Note: Use only stock ratio rocker arms.

For ultimate street performance, bolt on an Edelbrock Performer RPM Intake Manifold. A dual plane, high-rise design makes incredible power to 6500 RPM with streetable torque for great throttle response. Larger plenums and runners match the free-flowing exhaust, high-lift camshafts, and other modifications of high-output engines (especially Performer RPM Cams and Cylinder Heads that optimize performance). These intakes are not for emissions-equipped engines.
