The Holley Single-Plane Race intake manifold is a precision-engineered marvel, prioritizing top-notch performance. Boasting a race-bred, two-piece split feature typically exclusive to high-end race intakes, this manifold is tailored for GM LS Gen III engines featuring cathedral port heads. It's designed to accommodate 4150 style square bore flanged carburetors or throttle body EFI systems.
Tailored for high-performance and racing engine applications in the 5.3 to 6.2+ liter displacement range, the LS Race single-plane intake manifold is optimized for maximum engine speeds ranging from 6000 to 7000 rpm, contingent on the specific engine combination. Its single-plane design ensures unparalleled performance across the entire RPM spectrum, reaching peak power up to 7000 rpm.
Noteworthy is the innovative split feature of the Holley LS Race manifold, allowing easy disassembly for direct access to internal plenum and port surfaces. This facilitates a seamless process for custom porting and matching. The inclusion of shoulder bolt locators and an O-ring seal ensures straightforward and precise reassembly.
