Edelbrock Part # 71196 Performer RPM LS3 intake manifold is designed for Gen IV engines with LS3, L92 and L76 rectangular port cylinder heads. The Performer RPM LS3 manifold 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. This manifold includes an MSD Ignition Timing Control Module #6012, including passages for routing the coil wire harness, for a clean look. A special throttle and trans bracket that works with 700R-4, 200-4R and Turbo 350 transmissions is also included, making this an easy retro-fit into any muscle car, street rod or marine application.
