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 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 only 14 lbs. Performer RPM LS3 includes a provision for mounting an MSD Ignition Timing Control Module #6014, including passages for routing the coil wire harness underneath the plenum, for a clean look. A special throttle and trans bracket that works with 700-R4, 200-4R and Turbo 350 transmissions is also included, making this an easy retro-fit into any muscle car, street rod or marine application. #71196 includes MSD Ignition Timing Control Module #6014.
