4-bbl Spread-Bore Carb Flange (non-EGR)
Idle-5500 RPM Range

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:
Port Exit Dimensions: 1.14"x2.26"
Manifold Height: (A) 3.80" , (B) 4.75"
Carb Pad Height: 4.27"
Recommended Intake Gaskets: Fel-Pro 375-MS96005
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.
