Overview

Holley LS Split Design Carbureted Intake Manifolds

Holley LS split design carbureted intake manifolds are single-plane racing units designed with performance in mind. They feature a race-bred, 2-piece split feature that was previously only found on the most expensive race intakes. The manifolds will fit GM LS Gen III engines with cathedral port heads—and are intended for 4150-style square bore flanged carburetors or throttle body EFI. The LS Race single-plane intake manifold was designed for high performance/racing engine applications, 5.3 to 6.2+ liter displacement—and maximum engine speeds of 6,000 to 7,000 rpm, depending on the engine combination. This single-plane design provides optimal performance across the rpm spectrum, while providing maximum performance up to 7,000 rpm.

Features include:

* Maximum performance race design with hood clearance consideration
* Lighter than other split race intakes
* Split feature allows disassembly of the intake for direct access to internal plenum and port surfaces, making custom porting and matching a snap
* Shoulder bolt locators and O-ring seal make reassembly simple and precise
* 33 to 50 percent the price of other split race intakes
* Vacuum port options: Two 1/8 in., one 1/4 in., and one 3/8 in. NPT ports at the carb flange
