The manifold is designed to work with 4150 Style Throttle body EFI systems like the Holley 4150 style flange Universal Throttle Bodies. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features; like an updated plenum divider area, a 1\" shorter overall height than most single plane manifolds, and a choice of two distributor clamp locations. The isolated design of the air\/fuel passages helps to increase charge air density and performance. The fuel injector bores have back-cut exits in the runners for better fuel atomization. This design points the injectors at an angle to match the intake runner airflow angle. The black coated fuel rails and rail bracket assortment are included with the manifold for any easy installation with the injectors that you choose to use for your combination. Fuel rail designed for maximum throttle lever clearance.\n\n(Injectors are not included)\n\nThe 300-260 intake manifolds are designed 4150 style Throttle Body EFI applications on 1957-86 262-400cid Small Block Chevrolet engines and SBC engines equipped with 1987-91 L98 aluminum Corvette cylinder heads (non-EGR applications). 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.\n\nAlso Available: 20-86 Throttle Cable Bracket, 20-87 Kickdown Cable Bracket\u003cbr\u003e\u003cbr\u003eModification to the valve covers may be required when this manifold is used with some types of cylinder heads.\nThe fuel rail inlet threads are 9\/16-18 for a -6 port.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cul\u003e\n\u003cli\u003eSingle plane design with isolated plenum to keep the air charge cooler\u003c\/li\u003e\n\u003cli\u003e4150 square bore mounting flange to adapt most aftermarket throttle body designs\u003c\/li\u003e\n\u003cli\u003ePower band: 2500-7500 RPM\u003c\/li\u003e\n\u003cli\u003eHeight: Front 4.23\", Rear 5.33\"\u003c\/li\u003e\n\u003cli\u003ePort Size: 2.05??? height 1.02\" width\u003c\/li\u003e\n\u003cli\u003eLower throttle body mounting height to help with hood clearance\u003c\/li\u003e\n\u003cli\u003eBlack coated fuel rails with bracket assortment allowing different height fuel injectors\u003c\/li\u003e\n\u003cli\u003eFuel injectors are not included\u003c\/li\u003e\n\u003cli\u003eFuel rail designed for maximum throttle lever clearance\u003c\/li\u003e\n\u003cli\u003eSmall Block Chevrolet 262-400 cid engines equipped with 1996-2002 (L31) Vortec cylinder heads (non-EGR applications)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003eDetails:\u003cul\u003e\n\u003cli\u003eConstruction: Cast Aluminum\u003c\/li\u003e\n\u003cli\u003eEngine: Chevrolet Small Block Gen II (LT Based)\u003c\/li\u003e\n\u003cli\u003eFinish: Satin\u003c\/li\u003e\n\u003cli\u003eFront Height: 4.18\"\u003c\/li\u003e\n\u003cli\u003eFuel System Type: EFI\u003c\/li\u003e\n\u003cli\u003eManifold Type: High Rise\u003c\/li\u003e\n\u003cli\u003eRear Height: 5.28\"\u003c\/li\u003e\n\u003cli\u003eRPM Power Band: 2500-7500\u003c\/li\u003e\n\u003cli\u003eWarranty: Limited 90 Day\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003eLinks\u003cbr\u003e\u003ca href=\"https:\/\/www.holley.com\/\/documents.holley.com\/199r11939.pdf\/\"\u003eInstruction Sheet\u003c\/a\u003e","brand":"The Tuner Store","offers":[{"title":"Default Title","offer_id":44811655348310,"sku":"300-263","price":628.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/ezbuyco.com\/products\/holley-efi-sbc-4150-single-plane-fuel-injection-intake-manifold-chevy-small-block-v8-with-l31-vortec-cylinder-heads","provider":"EzBuyCo","version":"1.0","type":"link"}
