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.\u003c\/p\u003e\n\u003cp\u003e• Cast aluminum construction\u003c\/p\u003e\n\u003cp\u003e• Intended for use on N\/A or forced induction engines in the 6.0 to 7.0+ liter range with max power at 7000-8000+RPM\u003c\/p\u003e\n\u003cp\u003e• Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations\u003c\/p\u003e\n\u003cp\u003e• The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and for builders and fabricators as the foundation for custom induction systems.\u003c\/p\u003e\n\u003cp\u003e• 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\u003c\/p\u003e\n\u003cp\u003eThese parts should be used for the following applications: Performance, Racing, and Street Rodder where hood restrictions are not a consideration.\u003c\/p\u003e\n\u003cp\u003eLS1\/LS2\/LS6 Cathedral Port EFI Base Only\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003ePlenum Top Gasket Type - 3\/32” Round O-ring Cord\u003c\/li\u003e\n\u003cli\u003eRunner Length - 6.58” As-Cast Runner Cross-Sectional Area - Tapered 4.25 in² to 2.53 in²\u003c\/li\u003e\n\u003cli\u003eMounting Flange Gasket Type - Standard LS3 Molded O-ring\u003c\/li\u003e\n\u003cli\u003ePort Size - 2.49” H x 1.21” W\u003c\/li\u003e\n\u003cli\u003eBlack color\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":52732598124843,"sku":"300-227BK","price":1124.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/3645\/4465\/files\/503df7010398d9b77bc2ad5bd32eb04e3039ec7d.webp?v=1775534157","url":"https:\/\/www.burton-racing.com\/products\/ls1-2-6-hi-ram-im-efi-base-only-black","provider":"Burton-Racing","version":"1.0","type":"link"}
