Edelbrock Part # 2515 Buick B-4B intake manifold is a resurrection of the popular B-4B manifold made in the late 1960s for street 400-430-455 c.i.d. 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 carbs, making this manifold an excellent choice for both restoration and performance-minded Buick fans. 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 from off-idle through 5500rpm. This Performer intake manifold is ideal for passenger cars, trucks, 4x4s, tow vehicles and RVs.
