SBC Single Plane Intake Manifold w/4150 Flange

The SBC Single Plane Intake Manifold w/4150 Flange from Holley is designed for small-block Chevy builders who prioritize maximum airflow and responsive throttle characteristics across a wide RPM range. This single-plane design is ideal for street performance and mid-range torque development, balancing everyday drivability with peak horsepower.

Holley's single-plane configuration optimizes intake runner velocity and charge distribution, ensuring consistent combustion across all eight cylinders while minimizing low-end hesitation typical of dual-plane designs. The 4150 flange pattern allows for universal carburetor compatibility, accommodating both traditional four-barrel setups and modern EFI conversions with adapter plates.

Small-block Chevy enthusiasts, from street rodders to weekend circle-track competitors, will benefit from this manifold's precision engineering. Its cast aluminum construction provides excellent heat dissipation while maintaining a lightweight profile, crucial for responsive engine behavior.
