The Holley Single-Plane Race intake manifold embodies a dedication to performance, introducing a race-inspired, two-piece split feature previously exclusive to the most elite race intakes. Specifically designed for GM LS Gen III engines equipped with LS3/L92 heads, this manifold caters to 4150 style square bore flanged carburetors or throttle body EFI systems.
Engineered for high-performance and racing applications within the 5.3 to 6.2+ liter displacement range, the LS Race single-plane intake manifold ensures maximum engine speeds of 6000-7000 rpm (dependent on the engine combination). Its single-plane design optimizes performance across the entire RPM spectrum, delivering peak efficiency up to 7000 rpm.
The Holley LS Race manifold boasts a distinctive split feature, enabling effortless disassembly for direct access to internal plenum and port surfaces. This design streamlines custom porting and matching procedures, facilitated by shoulder bolt locators and O-ring seal, ensuring a straightforward and precise reassembly process.
