Buick 400-455ci V8
Back by popular demand. This intake manifold is a resurrection of the popular B-4B manifold made in the late 1960's for street 400-430-455ci Buick V8's. The only change to the original design is the addition of our proven Performer-style carb pad that accepts either square-bore or spread-bore carburetors. The Performer style carb pad is relocated for optimal fuel distribution, making this manifold an excellent choice for both restorations and performance-minded Buick fans.Installation Notes:
The rear egr/air port on this manifold has to be tapped and plugged with a pipe plug. The reason for this is that earlier heads did not have the provisions for egr in the head.
Idle-5500 RPM Power!
Performer manifolds are dual-plane, low-rise intake manifolds with a 180° firing order and a patented runner design that delivers outstanding performance. This patented design greatly improves torque over a wide rpm range, especially off-idle through 5500 rpm. Provides crisp throttle response.
