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.\u003c\/p\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eFits 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eDual-Plane Hi-Rise Intake Technology\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance Benefits\u003c\/strong\u003e\u003cbr\u003eDesigned 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCOMPATIBLE WITH\u003c\/strong\u003e\u003cbr\u003eCHEVROLET SMALL BLOCK GEN I V8 ENGINES\u003cbr\u003e• 4.3 L \/ 262 in3\u003cbr\u003e• 4.3 L \/ 265 in3\u003cbr\u003e• 4.4 L \/ 267 in3\u003cbr\u003e• 4.6 L \/ 283 in3\u003cbr\u003e• 4.9 L \/ 302 in3\u003cbr\u003e• 5.0 L \/ 305 in3\u003cbr\u003e• 5.0 L \/ 307 in3\u003cbr\u003e• 5.4 L \/ 327 in3\u003cbr\u003e• 5.7 L \/ 350 in3\u003cbr\u003e• 6.6 L \/ 400 in3\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCOMMON VEHICLE APPLICATIONS\u003c\/strong\u003e\u003cbr\u003eChevrolet Bel Air\u003cbr\u003eChevrolet Biscayne\u003cbr\u003eChevrolet Impala\u003cbr\u003eChevrolet Chevelle\u003cbr\u003eChevrolet El Camino\u003cbr\u003eChevrolet Camaro\u003cbr\u003eChevrolet Nova\u003cbr\u003eChevrolet Monte Carlo\u003cbr\u003eChevrolet C10 \/ C\/K Series Trucks\u003cbr\u003eGMC C\/K Series Trucks\u003cbr\u003eChevrolet Blazer\u003cbr\u003eChevrolet Suburban\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTES\u003c\/strong\u003e\u003cbr\u003e• Fits 1955–1986 Chevrolet Small Block Gen I V8 engines.\u003cbr\u003e• Fits 1987–1995 Gen I center-bolt cylinder heads with the included intake bolt-angle adapters.\u003cbr\u003e• Accepts 4150\/4160 square-bore carburetors.\u003cbr\u003e• Designed for 23-degree standard-port cylinder heads.\u003cbr\u003e• Intended for 600–700 CFM vacuum-secondary carburetors for typical street applications and 700–800 CFM mechanical-secondary carburetors for higher-performance street applications.\u003cbr\u003e• Not compatible with Vortec (8-bolt) cylinder heads.\u003cbr\u003e• Not compatible with LS or LT engines.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSPECIFICATIONS\u003c\/b\u003e\u003cbr\u003eBasic Operating RPM Range: Idle-5,500 RPM\u003cbr\u003eCarburetor Quantity: 1\u003cbr\u003eCNC Ported: No\u003cbr\u003eColor: Black\u003cbr\u003eDeck Height: Standard\u003cbr\u003eEGR: No\u003cbr\u003eIntake Manifold Height: 4.270 in.\u003cbr\u003eFuel System Type: Carbureted\u003cbr\u003eGasket Or Seal Included: No\u003cbr\u003eGrade Type: Performance\u003cbr\u003eIntake Port Shape: Oval\u003cbr\u003eMaterial: Aluminum\u003cbr\u003eSingle Or Dual Plane Type: Dual Plane\u003c\/p\u003e","brand":"Factory Outlet","offers":[{"title":"Default Title","offer_id":51299763421480,"sku":"53IM2701BK","price":144.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/8356\/5608\/files\/RSK-IM2701BK_02.jpg?v=1767033510","url":"https:\/\/www.topstreetperformance.com\/products\/1955-1986-chevy-sb-aluminum-intake-manifold-dual-plane-hi-rise-black","provider":"Top Street Performance","version":"1.0","type":"link"}
