{"product_id":"holley-efi-holley-hi-ram-lower-manifold-gm-ls7-300-229","title":"Holley EFI Holley Hi-Ram Lower Manifold - GM LS7 - 300-229","description":"• Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations\n\n• Cast aluminum construction.\n\n• Intended for use on N\/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.\n\n• EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.\n\nThe Holley GM LS7 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS7 style cylinder heads has outstanding potential for N\/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!\n\n• The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlenum Top Gasket Type – 3\/32” Round O-ring Cord\u003c\/li\u003e\n\u003cli\u003eRunner Length – 6.29”, As-Cast Runner Cross-Sectional Area – Tapered 4.67 in² to 2.84 in²\u003c\/li\u003e\n\u003cli\u003ePort Size – 2.49” Height x 1.21” Wide\u003c\/li\u003e\n\u003cli\u003eMounting Flange Gasket Type – Standard LS3 Molded O-Ring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e LS7 EFI Base Only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBasic Operating RPM Range:\u003c\/strong\u003e 3500-8000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburetor Flange:\u003c\/strong\u003e N\/A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburetor Quantity:\u003c\/strong\u003e N\/A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburetor Studs Included:\u003c\/strong\u003e N\/A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCNC Ported:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Natural\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Cast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Head Port Shape:\u003c\/strong\u003e Raised Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeck Height:\u003c\/strong\u003e 9.24 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEGR Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e GM LS7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Style:\u003c\/strong\u003e N\/A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Injectors Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Rail(s) Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel System Type:\u003c\/strong\u003e EFI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Or Seal Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntake Port Gasket(s) Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNitrous Bung(s) Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Engine Intake Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlenum Finish:\u003c\/strong\u003e Natural\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Intake Manifold Base\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable Runners:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable Top\/Lid:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle Or Dual Plane Type:\u003c\/strong\u003e Single Plane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrottle Body Bore Diameter:\u003c\/strong\u003e N\/A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrottle Body Gasket Included:\u003c\/strong\u003e N\/A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrottle Body Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType of Component:\u003c\/strong\u003e Lower Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Ports:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eThese parts should be used for the following applications: Racing\/Performance\/Street Rodder where hood restrictions are NOT a consideration.\u003c\/p\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":49715191021806,"sku":"HLY-300-229","price":1065.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/0572e2a30b2e3b4c7825190710e04bdeb7b0d624.jpg?v=1791567017","url":"https:\/\/elmosspeedshop.com\/products\/holley-efi-holley-hi-ram-lower-manifold-gm-ls7-300-229","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
