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 300-290\u003cbr\u003e\u003cbr\u003eTechnical Data:\n As-Cast Runner Cross-Sectional Area - 4.5 in² at the runner entry tapered to 3.2 in² at the flange exit\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.\n A-B Height - 7.20\" (0° carb flange angle)\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 Throttle Body Flange - Standard 4150 for up to 1-3\/4\" diameter throttle bores\n Port Size- 2.59\" Height x 1.28\" Wide\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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• Split feature making porting efforts easy!\u003cbr\u003e• Lighter than other split race intakes\u003cbr\u003e• Vacuum Port options include (2) 1\/8, (1) 1\/4, and (1) 3\/8, NPT ports at the carb flange\u003cbr\u003e• Captured O-ring seals at head ports and split\u003cbr\u003e• 33 to 50% the price of other split race intakes\u003cbr\u003e• Billet Fuel Rails and rail mounting hardware included.\u003cbr\u003e• Maximum performance race design with hood clearance consideration\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.
