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

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

? Throttle Body Flange - Standard 4150 for up to 1-3/4 inch diameter throttle bores ?

Port Size- 2.59 inch Height x 1.28 inch Wide 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.

Features and Benefits:

  • Split feature making porting efforts easy! Lighter than other split race intakes Vacuum Port options include (2) 1/8, (1) 1/4, and (1) 3/8, NPT ports at the carb flange Captured O-ring seals at head ports and split 33 to 50 percent the price of other split race intakes Billet Fuel Rails and rail mounting hardware included
  • Maximum performance race design with hood clearance consideration

Associated Comments:

  • Two 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.
