The Holley Single-Plane Race intake manifold is meticulously crafted with a focus on high-performance capabilities. Featuring an exclusive two-piece split design, previously seen only in premium race intakes, this manifold is tailored for GM LS Gen III engines with cathedral port heads. It accommodates 4150 style square bore flanged carburetors or throttle body EFI systems.
Designed for high-performance and racing engine applications in the 5.3 to 6.2+ liter displacement range, the LS Race single-plane intake is optimized for maximum engine speeds ranging from 6000 to 7000 rpm, contingent on the specific engine configuration. Its single-plane design ensures peak performance across the RPM spectrum, delivering exceptional power up to 7000 rpm.
Noteworthy is the innovative split feature of the Holley LS Race manifold, facilitating easy disassembly for direct access to internal plenum and port surfaces. This makes custom porting and matching a straightforward process. With shoulder bolt locators and an O-ring seal, reassembly becomes a precise and hassle-free task.
