GM LS Rectangle Port Carbureted Dual Plane Alu. Intake Manifold

This GM LS Rectangle Port Carbureted Dual Plane Aluminum Intake Manifold is built for street-performance Gen IV LS rectangle-port engines where you want the simplicity of a carb and strong torque without giving up top-end pull. The dual-plane layout is designed to sharpen throttle response and build usable power across a broad range, making it a solid choice for a street car that still wants to hit hard when you lean into it.

Cast from lightweight aluminum with a low-profile design, it helps with hood clearance and manages heat well compared to heavier castings. It’s set up for a single 4150 square-bore carburetor and includes the needed gasket/seal, keeping the install straightforward on compatible Gen IV LS-based small-block V8 applications like a 6.2L/376ci.
