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.\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.\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.\nTechnical Data:\n? A-B Height - 7.25\" (0° carb flange angle)\n? Port Size- 2.59\" Height x 1.28\" Wide\n? Carburetor Flange - Standard 4150 for up to 1-3\/4\" diameter throttle bores\n?
