Edelbrock part #2701-BP Performer EPS intake manifold is for 1986 and earlier 262-400 cubic-inch Chevys. Design is optimized for Edelbrock EPS or AVS2 carburetors, although any 4150 style carburetor will fit. Edelbrock's Patented dual-plane, low-rise design with a 180-degree firing order greatly improves torque over a wide rpm range and gives excellent throttle response. The Edelbrock Performer EPS intake manifold has a runner design that's tuned for peak torque at 3500 rpm on a 350-inch engine making it ideal for power from off-idle to 5500 rpm. Dyno tests showed gains of 5 hp and 9 ft-lbs. of torque over the Edelbrock Performer manifold #2101 on a 350 Chevy. This PN 2701-BP version comes with a beautiful reflective Black Plasma finish that is durable and easy to maintain. The Plasma finishes are applied by a fully automated 7 stage prewash and 4 stage finish. A durable clear powder coat finises the process.
