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\n As-Cast Runner Cross-Sectional Area - 4.5 in² at the runner entry tapered to 3.2 in² at the flange exit\n\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\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\n Port Size- 2.59\" Height x 1.28\" Wide\n\n Carburetor Flange - Standard 4150 for up to 1-3\/4\" diameter throttle bores\n\nTechnical Data:\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCaptured O-ring seals at head ports and split\u003c\/li\u003e\n\u003cli\u003e33 to 50% the price of other split race intakes\u003c\/li\u003e\n\u003cli\u003eSplit feature making porting efforts easy!\u003c\/li\u003e\n\u003cli\u003eBlack Finish\u003c\/li\u003e\n\u003cli\u003eLighter than other split race intakes\u003c\/li\u003e\n\u003cli\u003eVacuum Port options include (2) 1\/8, (1) 1\/4, and (1) 3\/8, NPT ports at the carb flange\u003c\/li\u003e\n\u003cli\u003eMaximum performance race design with hood clearance consideration\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 Carbureted single plane split-design race intake manifold.
