Chevrolet LS1 V8 Manifolds







Chevrolet LS1 V8


Performer RPM LS1 (1500-6500 rpm)


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 three timing curves. A special throttle and trans bracket that works with 700R-4 and Turbo 350 transmissions is included, making the LS1 engine an easy retro-fit into any muscle car, street rod or marine application.

hey there, ive got a carbureted 5.3 setup and it is pretty knarly! depends on how much horsepower ur gonna push but if ur in the 3-400 range a holley 670 does well anymore than that go ahead and jump to a 750 or 770. gm performance parts sells a hot cam kit that comes with springs as well, which u will need and it sells for abt $4oo i believe (not a bad deal). edelbrock has a couple of nice cam options too. do u know which model 5.3 u have ?? Lm7,L33... ?
