Also, these manifolds will work with any SBC engine equipped with aftermarket cylinder heads, as long as they have a standard port flange opening and mounting bolt locations.\u003c\/p\u003e\u003cp\u003eThe new single plane intake manifold is designed to provide a broad RPM powerband for high-performance street\/strip engine applications to a maximum engine speed of 7500 RPM. The carburetor-mounting pad is designed to accept all stock or aftermarket square-bore carburetors with manual or electric chokes.\u003c\/p\u003e\u003cp\u003eThese intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features, like an updated plenum divider area, a 1 inch shorter height than the 300-25 manifold, and a choice of two distributor clamp locations. The isolated design of the air\/fuel passages helps to increase charge air density and performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures and Benefits:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePower band: 2500-7500 RPM Square Bore Carburetor Mounting Flange Isolated Water cross-over Port Size: 1.92 inch height 1.20 inch width Height: Front 4.18 inch, Rear 5.28 inch Single Plane with Isolated Plenum\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eAssociated Comments:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eModification to the valve covers may be required when this manifold is used with some types of cylinder heads.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eDetails:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBarrel Quantity: 4.0\u003c\/li\u003e\n\u003cli\u003eBasic Operating RPM Range: 2500-7500 RPM\u003c\/li\u003e\n\u003cli\u003eCnc Ported: No\u003c\/li\u003e\n\u003cli\u003eCarburetor Flange: 4150 Square Bore\u003c\/li\u003e\n\u003cli\u003eCarburetor Quantity: 1.0\u003c\/li\u003e\n\u003cli\u003eCarburetor Studs Included: No\u003c\/li\u003e\n\u003cli\u003eColor: Natural\u003c\/li\u003e\n\u003cli\u003eConstruction: Cast\u003c\/li\u003e\n\u003cli\u003eCylinder Head Port Shape: Rectangle\u003c\/li\u003e\n\u003cli\u003eDeck Height: 9.025 Inch\u003c\/li\u003e\n\u003cli\u003eEGR Port: No\u003c\/li\u003e\n\u003cli\u003eEngine: Chevrolet Small Block - 87+ Aluminum Heads\u003c\/li\u003e\n\u003cli\u003eFlange Style: 4150 Square Bore\u003c\/li\u003e\n\u003cli\u003eFront Maximum Height: 4.18 Inch\u003c\/li\u003e\n\u003cli\u003eFuel Injectors Included: No\u003c\/li\u003e\n\u003cli\u003eFuel Rail(s) Included: No\u003c\/li\u003e\n\u003cli\u003eFuel System Type: Carb\u003c\/li\u003e\n\u003cli\u003eGasket Or Seal Included: No\u003c\/li\u003e\n\u003cli\u003eGrade Type: Performance\u003c\/li\u003e\n\u003cli\u003eIntake Port Gasket(s) Included: No\u003c\/li\u003e\n\u003cli\u003eManifold Type: High Rise\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003cli\u003eNitrous Bung(s) Included: No\u003c\/li\u003e\n\u003cli\u003ePlenum Finish: Natural\u003c\/li\u003e\n\u003cli\u003eRear Maximum Height: 5.28 Inch\u003c\/li\u003e\n\u003cli\u003eRemovable Runners: No\u003c\/li\u003e\n\u003cli\u003eRemovable Top\/Lid: No\u003c\/li\u003e\n\u003cli\u003eSingle Or Dual Plane Type: Single Plane\u003c\/li\u003e\n\u003cli\u003eThrottle Body Bore Diameter: 3.6\u003c\/li\u003e\n\u003cli\u003eThrottle Body Gasket Included: No\u003c\/li\u003e\n\u003cli\u003eThrottle Body Included: No\u003c\/li\u003e\n\u003cli\u003eVacuum Ports: Yes\u003c\/li\u003e\n\u003cli\u003eWarranty: Manufacturer's Limited 90 Day Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Guide:\u003c\/strong\u003e \u003ca href=\"https:\/\/www.asapnetwork.org\/sites\/default\/files\/bbvl\/installation\/693676d6046eb105af16190a22dc3f54.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDownload PDF\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation \/ Product Video:\u003c\/strong\u003e \u003ca href=\"https:\/\/youtu.be\/sWiK0tCHpS4?si=M_52zIdc0GJk9Si_\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eWatch on YouTube\u003c\/a\u003e\u003c\/p\u003e\n\u003chr\u003e\u003cp class=\"prop65-warning\"\u003e\u003cstrong\u003e⚠️ California Proposition 65 Warning\u003c\/strong\u003e\u003cbr\u003eCalifornia Residents: This product can expose you to chemicals which are known to the State of California to cause cancer or other reproductive harm.
