The Edelbrock Performer for Buick 455 is a non-EGR, dual-plane intake manifold designed for 400–430–455 c.i.d. Buick big-block V8s in street applications. Its low-rise layout and 180-degree firing-order tuning enhance torque and throttle response through about 5,500 rpm. It fits under cold-air induction hoods but is not compatible with Buick 350 engines.
