{"product_id":"hly-300-260","title":"Holley EFI SBC 4150 Single Plane EFI Intake Manifold - Chevy Small Block V8","description":"\u003cp\u003eThe new single plane EFI 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 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003cbr\u003eHolley laser etched logos on the black coated fuel rails and bracket assortment are included so that you can install the injectors of your choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e EFI Single Plane Manifold 1962-1986 262ci-400ci, 1987-later with Aluminum Heads\u003c\/p\u003e\u003cp\u003e\u003cem\u003eInstallation note:\u003c\/em\u003e Modification to the valve covers may be required when this manifold is used with some types of cylinder heads._x000D_\nThe fuel rail inlet threads are 9\/16-18 for a -6 port.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBasic Operating RPM Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2500-7500 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCNC Ported\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCarburetor Flange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSquare\/4150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCarburetor Quantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCast\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCylinder Head Port Shape\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRectangle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDeck Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9.025 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEGR Port\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eChevrolet Small Block Gen I\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlange Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4150 Square Bore\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFront Maximum Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.18 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFuel Inlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9\/16-18\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFuel System Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEFI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManifold Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh Rise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlenum Finish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNatural\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRear Maximum Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5.28 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRemovable Runners\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRemovable Top\/Lid\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSingle Or Dual Plane Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle Plane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThrottle Body Bore Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.6 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVacuum Ports\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eProduct Video\u003c\/h3\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:1em 0;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/6G3R9GdXV4w\" title=\"Product video\" frameborder=\"0\" allow=\"accelerometer;
