Edelbrock Performer RPM LS1 Manifold & Timing Control Module, Satin (non-EGR)

PERFORMER RPM LS1 (1500-6500 RPM)
This powerful 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. A special throttle and trans bracket that works with 700R4, 2004-R and Turbo 350 transmissions is included, making the LS1 engine an easy retro-fit into any muscle car, street rod or marine application.

Carburetor Recommendations for the Performer RPM LS1: Edelbrock Thunder Series AVS or Performer Series carb, 600-800 cfm. Installation Notes: Uses LS1/LS6 style individual port o-ring seals or Edelbrock #7386. Crankshaft sleeve #HP3795 and Flexplate #HP4004 is recommended when using a TH350, TH400 or 700R4 on a LS1; these items are available through Hughes Performance retailers or you can call Hughes at 800-274-RACE.
