Fits all GM LS Gen III or IV engines equipped with LS3\/L92 cylinder heads\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e 300-290BK\u003cbr\u003e\u003cbr\u003e As-Cast Runner Cross-Sectional Area - 4.5 in² at the runner entry tapered to 3.2 in² at the flange exit\nThe LS Race single-plane intake manifold was designed for hi-performance\/racing engine applications, 5.3 to 6.2+ liter displacement, and maximum engine speeds of 6000-7000 rpm, depending on the engine combination. This single-plane design provides optimal performance across the RPM spectrum while providing maximum performance up to 7000 rpm.\n Port Size- 2.59\" Height x 1.28\" Wide\n Throttle Body Flange - Standard 4150 for up to 1-3\/4\" diameter throttle bores\nTechnical Data:\nThe Holley LS Race manifold incorporates a split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, making custom porting and matching a snap. With shoulder bolt locators and O-ring seal, reassembly is simple and precise.\nThe new Holley Single-Plane Race intake manifold were designed with performance in mind. They feature a race bred, two piece split feature that was previously only found on the most expensive race intakes. The manifold will fit GM LS Gen III engines with LS3\/L92 heads and are intended for 4150 style square bore flanged carburetors or throttle body EFI.\n A-B Height - 7.20\" (0° carb flange angle)\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• Split feature making porting efforts easy!\u003cbr\u003e• Vacuum Port options include (2) 1\/8, (1) 1\/4, and (1) 3\/8, NPT ports at the carb flange\u003cbr\u003e• Lighter than other split race intakes\u003cbr\u003e• Maximum performance race design with hood clearance consideration\u003cbr\u003e• Billet Fuel Rails and rail mounting hardware included.\u003cbr\u003e• 33 to 50% the price of other split race intakes\u003cbr\u003e• Captured O-ring seals at head ports and split\u003cbr\u003e\u003cbr\u003e\u003cem\u003eTwo different length fuel rail bracket sets are included; the long brackets are for mounting the fuel rails at a height for Bosch style EV1 type fuel injectors. The short brackets are for mounting the fuel rails at a height for GM OE LS7 fuel injectors. When using the OE GM LS7 injector, the O-ring on the outlet (intake manifold) end of the injector must be changed to the O-ring supplied in the short bracket pack.\u003c\/em\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":48275875987683,"sku":"300-290BK","price":1586.8,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/0821\/9875\/files\/a28fa44f38f8d63b7cffc3ec2cd5983e.jpg?v=1771069103","url":"https:\/\/fastlanespares.co.nz\/products\/holley-300-290bk-single-plane-efi-split-design-race-intake-manifold-gm-ls3l92-black","provider":"Fast Lane Spares","version":"1.0","type":"link"}
