Edelbrock Buick B4 B Manifold

This Edelbrock B-4B intake manifold is a reproduction of a popular design from the late 1960s, specifically for Buick 400, 430, and 455 cubic inch V8 engines. The original design has been updated with Edelbrock's Performer-style carb pad, which is a smart addition because it accepts both square-bore and spread-bore carburetors. This makes it a solid choice whether you're aiming for a period-correct restoration or looking to boost performance on your street-driven Buick.

The dual-plane, low-rise design with a 180-degree firing order is a key feature that really helps improve torque across a wide RPM range. You'll notice better throttle response from when you first start moving all the way up to about 5500 RPM. This manifold is well-suited for a variety of applications, including passenger cars, trucks, 4x4s, tow vehicles, and RVs. It's designed to fit right and work effectively with your Buick big-block, offering a notable improvement over stock intake manifolds.

This manifold is ideal for Buick models from the late 1960s through the mid-1970s, including vehicles like the Electra, LeSabre, and Riviera. It's a non-EGR manifold, so be sure to check local emissions regulations before installation, as it is not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your Buick V8 or just looking for a proven intake upgrade, this B-4B manifold is a well-built option.
