The new Holley Single-Plane Race intake manifold is designed with maximum performance in mind. Featured is a two-piece split design that provides access for all levels of porting and modification. With shoulder bolt locators and O-ring seal, disassembly & reassembly is simple and precise. The manifold with AN-8 fuel rails fits GM LS Gen III engines with cathedral port heads and has a 4500 Dominator style carb flange for carburetors, EFI throttle bodies, or EFI throttle body elbows, and is configured with a LS MAP sensor port along with other NPT plenum vacuum or air-temp sensor ports. The LS Race single-plane intake manifold is designed for hi-performance/racing engine applications, 5.3 to 6.2+ liter displacements, N/A or with power adders. The large volume 4500 plenum and optimized runners provide airflow potential for Hi-RPM engines with max power at 7500-8000+ RPM.
