GM LS Victor Jr. Intake Manifold - 4150 Flange

The Edelbrock GM LS Victor Jr. Intake Manifold with 4150 flange is purpose-built for LS-series engine platforms requiring high-flow induction architecture without the complexity of dual-plane designs. Designed for enthusiasts and professional engine builders who demand efficient air delivery across mid-to-high RPM ranges, this single-plane aluminum manifold transforms intake performance by optimizing plenum velocity and cylinder filling. Whether you're upgrading a street machine or fine-tuning a performance platform, the Victor Jr. delivers the responsiveness and throttle response that separates capable engines from truly powerful ones.

Constructed from lightweight aluminum and finished in natural (bare) form, the GM LS Victor Jr. features a single-plane design that routes charge evenly to all eight cylinders, eliminating the uneven distribution inherent in traditional dual-plane manifolds. The 4150 square-bore flange ensures compatibility with standard Holley and Edelbrock carburetor platforms while maintaining precise port matching to L76, L92, and LS3 cylinder head configurations. At 17.79 lbs, the manifold's compact footprint (15.8 x 7.8 x 24.15 inches) maximizes underhood clearance while its aluminum construction resists heat soak, enabling cooler charge temperatures and denser air columns for measurable power gains.

Professionals and serious tuners installing this manifold on GM LS-series engines—particularly L76, L92, and LS3 variants—will appreciate its bolt-on compatibility and immediate response improvements across the powerband. Installation requires standard intake manifold gasket sets and carburetor spacer adapters depending on your fuel delivery method; professional port matching prior to assembly optimizes flow characteristics. The natural aluminum finish allows easy inspection and cleaning, making maintenance and future modifications straightforward for both street and competition applications seeking reliable, repeatable performance.
