Chevy Small Block Carbureted Dual Plane Aluminum Intake Manifold - Satin

• Chevy small block dual plane intake is built for carbureted systems with Spread Bore (4150 Square Bore with Included Adapter) carburetor flange compatibility.

• Operating range: Idle-5,500 RPM. Deck height: Standard. Designed to match the camshaft, cylinder heads, and vehicle use.

• Aluminum construction with satin finish supports durability, sealing, and clean engine-bay presentation.

• Front/center/rear height: 3.500 in., 4.050 in., 4.600 in. EGR: Yes. Verify hood clearance, distributor clearance, gasket alignment, and accessory spacing.

For applications that need reliable intake airflow and clean engine-bay fitment, this intake manifold combines durable construction with application-focused runner and plenum design.

Airflow & Performance Design
The intake runner and plenum design help support balanced airflow delivery between cylinders while maintaining stable throttle response and dependable street-driven performance.

Construction & Engine-Bay Fitment
The manifold construction to support long-term durability, heat management, and a clean installed appearance in demanding engine-bay environments.

Installation Considerations
Proper installation requires confirming cylinder head compatibility, intake gasket alignment, carburetor or throttle-body configuration, distributor clearance, and hood clearance before final assembly.

System Matching
Verify fuel system compatibility, throttle linkage setup, vacuum routing, sensor provisions, and accessory clearance before installation. This intake manifold is intended for properly matched engine combinations.

What vehicles and engines is this intake designed for?
Designed for 1955–1986 Chevy Small Block engines, with compatibility for later models when used with appropriate adapters.

Will this fit a 350 Small Block Chevy?
Yes, this intake is fully compatible with 350 SBC engines, along with other common displacements like 305, 327, and 400.

Will this intake work with Vortec heads or LT1 engines?
This intake is not compatible with reverse-flow LT1-style heads and may require modifications or a different manifold for Vortec applications.

Can I run both square bore and spread bore carburetors?
Yes, the intake is designed for spread bore carburetors but includes an adapter plate and gasket to support square bore carburetors as well.

What RPM range does this intake operate in?
Designed for idle through approximately 5,500 RPM, delivering strong low-end torque and mid-range performance.

How does this intake improve performance?
It enhances airflow efficiency, improving throttle response, torque, and overall drivability across the RPM range.

Is this intake better for street or race use?
This manifold is best suited for street performance and mild street/strip applications where low- and mid-range power is important.

What type of intake manifold is this?
This is a dual-plane intake manifold, which improves low-end torque and drivability by separating airflow into two planes.

Will this intake clear a stock hood?
Yes, it features a low-profile design that helps maintain hood clearance in most factory engine bays.

What material is this intake made from?
It is made from lightweight aluminum, which improves heat dissipation and reduces overall engine weight.

Is this a direct bolt-on intake manifold?
In most cases, this intake installs as a direct replacement for factory SBC manifolds, though proper gaskets and setup are recommended.

What additional parts are needed for installation?
You may need intake gaskets, carburetor linkage adjustments, and possibly an adapter depending on your carburetor configuration.

Will this intake improve throttle response on my SBC?
Yes, the dual-plane design increases air velocity at lower RPMs, resulting in improved throttle response and smoother drivability.

Is this a good upgrade from a stock intake?
Yes, this intake offers better airflow and improved power delivery across the usable RPM range compared to factory manifolds.

What are the benefits of the satin finish?
The satin finish offers a clean, OEM-style look with low maintenance and resistance to fingerprints and oxidation.

Does the satin finish require maintenance?
Minimal maintenance is required—occasional cleaning is typically enough to keep it looking good.
