SBC Intake Manifold - 4150 Flange

The SBC Intake Manifold - 4150 Flange by Brodix is a purpose-built induction component designed for small-block Chevrolet engines seeking improved volumetric efficiency and reliable air delivery. This manifold serves builders, restoration shops, and performance enthusiasts who demand precision engineering over generic alternatives. Whether you're assembling a street engine, race platform, or vintage restomod, a quality intake manifold is critical to converting fuel and air into consistent power across the RPM band.

The 4150 flange designation indicates this manifold accepts standard Holley-pattern carburetors and throttle bodies, the industry-wide mounting standard for aftermarket SBC carburetor applications. Brodix manifolds are renowned for optimized port design that minimizes flow restrictions and promotes even distribution to all cylinders, eliminating the lean/rich imbalances common in poorly designed units. The manifold's cast construction and finished surfaces ensure durability under sustained heat cycles, while the 18.75 lb weight reflects a robust, precision-cast component rather than a lightweight but fragile alternative. Proper runner geometry and plenum volume are engineered to support both naturally aspirated and carbureted configurations without sacrifice.

This intake is ideal for SBC builds ranging from 283 to 400 cubic inches, compatible with most small-block Chevrolet block variants when paired with appropriate gaskets and hardware. Professional installers value Brodix manifolds for their repeatable fitment and zero-compromise flow characteristics, making them a trusted choice for high-horsepower engines that cannot afford mid-range flatspots or carburetor tuning headaches. Installation requires standard intake gaskets, fasteners, and carburetor adapter plates specific to your block and carb combination—verify flange type and port configuration before purchase to ensure seamless integration into your engine bay.
