? As-Cast Runner Cross-Sectional Area - 4.5 in2 at the runner entry tapered to 3.2 in2 at the flange exit The 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. ?

Port Size- 2.59 inch Height x 1.28 inch Wide ? Throttle Body Flange - Standard 4150 for up to 1-3/4 inch diameter throttle bores Technical Data: The 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. The 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.

? A-B Height - 7.20 inch (0 carb flange angle)
