400 cubic-inch Chevys. Edelbrock’s Patented Dual-plane, low-rise design with a 180-degree firing order greatly improves torque over a wide rpm range for excellent throttle response. This Performer EPS intake manifold combines a modern runner design with a front mounted oil fill tube for those who want the vintage look of our Classic valve covers with no breathers. Includes Oil Fill Tube (not installed) and matching push-in breather cap. The Oil Fill Tube and Breather are also available separately as #4803. This intake manifold is optimized to deliver superior performance with Edelbrock square-bore Performer Series or Thunder Series AVS carburetors. This small-block Chevy manifold has a runner design that's "tuned" for peak torque at 3500 rpm on a 350-inch engine and it's 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 intake manifold #21011 on a 350 Chevy. From 3000 to 4500 rpm, the increases averaged 5+ ft-lbs. of torque for more performance where you need it most. This manifold offers a durable black power coated finish for long lasting protection and a distinctive look.
