Designed for Gen IV engines with LS3, L92 and L76 rectangular port cylinder heads. The Performer RPM LS3 is ideal for anybody looking to build a carbureted LS3 or LS2 engine with an operating range between 1,500 - 6,500 rpm. It allows the use of a carburetor on these originally computer-controlled engines, offering maximum power and a broad torque curve. It features a high-rise dual-plane design combined with a plenum that has been optimized for square-bore carburetors. Our advanced casting techniques allowed us to create a lightweight casting that weighs in at 14 lbs.
