Edelbrock part #71187 Performer RPM LS1 intake manifold is designed for the popular Chevrolet LS1 (5.7L) small-block V8 originally used in 1997 and later Corvettes and 1998-02 Camaros and Firebirds. It also fits the Corvette LS6 engine and any other Gen III engine including the LM7 (5.3L), LR4 (4.8L), and LQ4 (6.0L). It allows the use of a carburetor on these originally computer-controlled engines, offering maximum power and a broad torque curve from 1500 to 6500 rpm. The Performer RPM LS1 is available with an optional wiring harness and electronic Timing Control Module made by MSD this ignition module is for LS1 (24x) ignitions only and works with OE sensors to fire the Coil-on-Plug ignition system and offers a choice of six timing curves (sold separately). A special throttle and trans bracket that works with 700R-4, 200R-4 and Turbo 350 transmissions is included, making the LS1 engine an easy retro-fit into any muscle car, street rod or marine application.
