    Carbureted LS Manifolds

    This powerful manifold is designed for the popular Chevrolet LS1 5.7L small-block V8 originally used in 1997-Up Corvette and 1998-2002 Camaro/Firebird. It also fits the Corvette LS6 and Gen III LR4 4.8L, LM7 5.3L, and LQ4 6.0L engines. For maximum power and a broad torque curve from 1500-6500 RPM, this manifold allows the use of a carburetor on these originally computer-controlled engines. It made 410 HP and 418 ft/lbs TQ in dyno tests with camshaft 350-2215 and carburetor 350-1413.
