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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe 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. Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eEFI 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. Cast aluminum construction. 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003e\u003cu data-mce-fragment=\"1\"\u003eNOTE:\u003c\/u\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eThese parts should be used for the following applications: Racing\/Performance\/Street Rodder where hood restrictions are NOT a consideration.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003cu data-mce-fragment=\"1\"\u003eFeatures:\u003c\/u\u003e\u003c\/strong\u003e \u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003ePort Size - 2.49\" Height x 1.21\" Wide\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eMounting Flange Gasket Type - Standard LS3 Molded O-Ring\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003ePlenum Top Gasket Type - 3\/32\" Round O-ring Cord\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRunner Length - 6.29\", As-Cast Runner Cross-Sectional Area - Tapered 4.67 in² to 2.84 in²\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003cu data-mce-fragment=\"1\"\u003eSpecs:\u003c\/u\u003e\u003c\/strong\u003e \u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cb data-mce-fragment=\"1\"\u003eBrand:\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eHolley EFI\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cb data-mce-fragment=\"1\"\u003eColor\/Construction:\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eBlack Cast\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cb data-mce-fragment=\"1\"\u003eEngine:\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eGM LS7\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cb data-mce-fragment=\"1\"\u003eFuel System Type:\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eCarb\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cb data-mce-fragment=\"1\"\u003eProduct Type:\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eLower Intake Manifold Base\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\n\u003cb data-mce-fragment=\"1\"\u003eRPM Power Band:\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e3500-8000 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou can view and download the complete assembly instruction booklet \u003ca href=\"https:\/\/southwestspeed.com\/cdn\/shop\/files\/HOL_300-117Instructions.pdf\" style=\"color: red;\"\u003ehere\u003c\/a\u003e.\u003c\/p\u003e","brand":"HOL 300-229BK","offers":[{"title":"Default Title","offer_id":47881926148377,"sku":"HOL 300-229BK","price":921.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0829\/0477\/6985\/files\/HOL_300-229BK.jpg?v=1711130620","url":"https:\/\/southwestspeed.com\/products\/hol-300-229bk","provider":"Southwest Speed","version":"1.0","type":"link"}
