Upgrade your Chevrolet small block V8 with the Top Street Performance Dual Plane Hi-Rise Aluminum Intake Manifold, engineered for carbureted Gen I small block Chevy applications spanning 1955 through 1995. Compatible with ten SBC displacements — 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 cubic inches — this is one of the most versatile small block Chevy intake manifolds available for street-driven carbureted builds.

Designed to operate from idle through 5,500 RPM, the dual-plane runner layout delivers strong low- and mid-range torque and responsive throttle feel right where street-driven vehicles spend most of their time. Whether you're building a classic Camaro, Chevelle, Nova, or C10 truck, restoring a muscle car, or assembling a street rod around a Gen I small block Chevy, this hi-rise dual plane intake manifold delivers the broad powerband, drivability, and carburetor compatibility your combination needs.

The hi-rise plenum design, standing 4.270 inches tall, promotes strong airflow velocity through the intake tract while supporting compatibility with 600–700 CFM vacuum secondary carburetors in typical street applications and 700–800 CFM double pumper carburetors in higher-performance street builds. Constructed from lightweight aluminum, this SBC intake manifold reduces engine weight compared to heavier cast-iron factory units and dissipates heat more efficiently to help keep intake charge temperatures lower during street and performance use.

Fits 1955–1986 Gen I small block Chevy engines directly, and extends compatibility through 1987–1995 small block applications with the included adapters. Finished in black aluminum for a clean, performance-oriented appearance that suits everything from show-quality restorations to purpose-built street machines.

Dual-Plane Hi-Rise Intake Technology
The dual-plane runner design divides the intake plenum into two separate planes, each feeding alternating cylinders to maintain strong airflow velocity throughout the operating range. This configuration promotes balanced air-fuel distribution across all eight cylinders of the Gen I small block Chevy, supporting consistent low- and mid-range torque delivery from idle through 5,500 RPM — exactly where street-driven SBC builds produce the power that matters most. The hi-rise plenum height of 4.270 inches further enhances airflow velocity through the intake tract, helping optimize throttle response and fuel atomization for improved drivability across a wide range of small block Chevy displacements and carburetor combinations. The oval intake port shape ensures proper alignment with Gen I SBC cylinder heads for a reliable seal and consistent airflow path to each cylinder.

Performance Benefits
Designed for the full range of Gen I Chevrolet small block V8 displacements from 262 through 400 cubic inches, this dual plane hi-rise intake manifold supports improved airflow efficiency and stronger low-end torque compared to restrictive factory cast-iron intakes. Optimized for 600–700 CFM vacuum secondary carburetors in typical street applications and 700–800 CFM double pumper setups in higher-performance builds, this manifold pairs well with a wide range of popular 4-barrel carburetor options. The broad idle-to-5,500 RPM operating range makes it an excellent choice for daily drivers, weekend muscle cars, street rods, cruisers, and light truck performance builds.

What small block Chevy engines does this intake manifold fit?
This manifold fits Gen I Chevrolet Small Block V8 engines in 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 cubic inch displacements with standard deck-height blocks.

Will this fit my 1987-1995 Small Block Chevy?
Yes. The manifold fits 1955-1986 Gen I Small Block Chevy engines directly and extends compatibility through 1987-1995 applications using the included adapter set.

What carburetor size is recommended for this intake?
This manifold accepts a single 4-barrel carburetor. For typical street applications, a 600-700 CFM vacuum secondary carburetor is a common choice, while higher-performance combinations may benefit from a 700-800 CFM mechanical secondary carburetor. Final carburetor sizing should be based on engine displacement, camshaft specifications, and intended use.

What RPM range is this intake manifold designed for?
This dual-plane hi-rise intake is designed for idle-to-5,500 RPM operation, making it well suited for street driving, cruising, muscle car builds, and light truck performance applications.

Will this fit a Gen II, LT1, or LS Small Block Chevy?
No. This manifold is designed specifically for Gen I Small Block Chevy V8 engines. It is not compatible with Gen II (LT1), Gen III (LS), or later Small Block Chevy engine families.

Will this fit a Chevy Big Block V8?
No. This manifold is designed exclusively for Gen I Small Block Chevy V8 engines and is not compatible with Big Block Chevy applications.

What vehicles commonly use a Gen I Small Block Chevy engine?
Gen I Small Block Chevy engines were installed in a wide variety of GM vehicles, including the Chevrolet Camaro, Chevelle, Nova, Corvette, Impala, El Camino, Monte Carlo, C10 and C20 pickups, and many other Chevrolet and GMC models from 1955 through the mid-1990s.

Is this intake manifold EGR compatible?
No. This manifold does not include provisions for EGR (Exhaust Gas Recirculation).

Does this intake manifold include gaskets or hardware?
No. Intake gaskets and carburetor installation hardware are sold separately. Use Gen I Small Block Chevy-specific intake gaskets to ensure proper sealing.

What is the manifold height, and will it fit under my hood?
The manifold measures 4.270 inches in height. Hood clearance should always be verified before installation, especially in applications with limited engine bay clearance, such as early Camaros and Novas with factory hood lines.
