Description
Hi-Ram Intake Manifold Base. The Holley GM LS3/L92 Hi-Ram Carbureted Lower Intake Manifold is engineered as a robust intake base designed to optimize airflow for carbureted GM LS3 and L92 engines. This base manifold supports high-rpm operation and is intended for racing use only vehicles.
Construction and Appearance. Made from durable cast aluminum, the manifold features a natural finish that emphasizes its rugged build quality. It utilizes a single-plane design with as-cast tapered runners measuring 6.50 inches in length and tapering cross-sectional area from 4.25 to 2.77 square inches to enhance airflow dynamics.
Installation. The manifold bolts directly to compatible LS3/L92 cylinder heads using standard LS3 molded O-ring gaskets. It is a carbureted base only, requiring a separately sourced plenum-top mounting fabrication flange for completion. Installation may require fabrication and modifications depending on the application.
Warranty. This product includes a manufacturer’s limited 90-day warranty coverage against defects.
Application. This lower manifold base fits GM LS3/L92 engines and is compatible with 2010-2015 Camaro SS models equipped with these engines. It is intended for racing-use vehicles only and is not designed for general street use.
