SBC SHP Intake Manifold Dual Plane 4150 Flange

The DART SBC SHP Intake Manifold Dual Plane 4150 Flange is a high-flow aluminum intake designed for small-block Chevy engines seeking improved low-to-mid-range torque and consistent manifold velocity across load conditions. Built from aluminum construction and finished in natural bare metal, this dual-plane design distributes fuel and air charge unevenly between cylinder banks, optimizing volumetric efficiency for street and light performance applications where responsive throttle behavior matters.

The dual-plane architecture splits incoming charge between the primary and secondary plenum chambers, allowing the manifold to work effectively across a wider RPM band than single-plane designs. The square-bore 4150 flange accommodates standard small-block carburetors and is compatible with common SBC bolt patterns. At 18.3 pounds, the aluminum construction provides weight savings compared to cast-iron manifolds while maintaining structural rigidity under typical engine bay conditions. The natural finish allows for custom coating or painting to match your engine's aesthetic.

This manifold suits builders and engine shops working on small-block Chevy platforms for street machines, restorations, or mild performance builds where balanced power delivery and part availability are priorities. The 4150 flange specification ensures straightforward carb swaps and sourcing, reducing fitment complications during engine assembly or upgrades. Buyers should verify carburetor compatibility and existing intake port configuration before installation to confirm proper sealing and runner alignment with their specific cylinder head revision.

DART has built a solid reputation in the SBC marketplace for producing cost-effective cast and aluminum intake solutions. The SHP series targets builders seeking proven designs without premium pricing. Dual-plane intake manifolds remain the practical standard for street and marine SBC applications, offering the torque characteristics and throttle response that carbureted small-block engines deliver reliably across daily driving and moderate boost scenarios.
