"This powerful new manifold is designed for the popular Chevrolet LS1 (5.7L) small-block V8 originally used in 1996 and later Corvettes and 1997-02 Camaros and Firebirds. It also fits the Corvette ZO6 engine and any other Gen III engines including the LM7 (5.3L), LR4 (4.8L), and LQ4 (6.0L). The Performer RPM LS1 manifold allows the use of a carburetor on these originally computer-controlled engines, offering maximum power and a broad torque curve, providing optimum performance from 1500 to 6500 rpm. This manifold includes a unique electronic Timing Control Module made by MSD® which works with OE sensors to fire the “distributorless” ignition system and offers a choice of three timing curves. We have also included a special throttle and trans bracket that works with 700R-4 and Turbo 350 transmissions making the LS1 engine an easy retro-fit into any muscle car, street rod or marine application."
