Carbureted LS Manifolds
Designed for Gen IV engines with LS3, L92 and L76 rectangular port cylinder heads. The Performer RPM LS3 manifold is ideal for anybody looking to build a carbureted LS3 or LS2 engine with an operating range between 1,500 - 6,500 rpm. It allows the use of a carburetor on these originally computer-controlled engines, offering maximum power and a broad torque curve. It features a high-rise dual-plane design combined with a plenum that has been optimized for square-bore carburetors. Our advanced casting techniques allowed us to create a lightweight casting that weighs in at 14 lbs. Installation Notes

Edelbrock engineered Performer RPM LS intake manifolds allow the use of a square bore carb on these originally computer-controlled engines. Designed originally for the LS1 V8, they can be used on Gen III and Gen IV small blocks with cathedral or rectangle port heads. These manifolds will offer maximum power & optimum performance from 1500-6500 RPM.Satin or polished, these manifolds are available in a kit that also includes:
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
