Chevrolet 262-400 Small-Block V8 PERFORMER RPM LS1 (1500-6500 rpm) For Chevrolet LS1 V8
This powerful new 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. This
manifold made 410 hp and 418 ft/lbs. of torque in dyno tests with our matching cam #2215
and Performer Series carb #1413. The Performer RPM LS1 includes a wiring harness and
unique electronic Timing Control Module made by MSD® which 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 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.
