Additionally, the manifold's runner length has been optimized to provide excellent cylinder-to-cylinder scavenging, ensuring a more efficient fuel-air mixture and improved engine performance.
The 71197 Performer RPM Manifold is constructed from high-quality aluminum material, which not only contributes to its durability but also helps in keeping the weight of the intake system to a minimum. The manifold's surface is finished with a polished appearance, giving it a clean and attractive look that is sure to complement any engine bay.
The manifold comes with a set of factory-installed, long-tube, heat-coated headers that are designed to provide optimal exhaust flow and scavenging. These headers are made of 304 stainless steel, which is known for its high strength and resistance to corrosion. Edelbrock's attention to detail extends to the inlet and outlet connections, which are equipped with OEM-style, 180-degree flanged ports. These ports make for an easier installation process and ensure a proper fit with OEM-style carburetors and exhaust systems.
In summary, the Edelbrock 71197 Performer RPM Manifold is a top-tier intake solution for GM LS3 engines using 4-barrel carburetors. Its RPM design provides improved airflow and cylinder-to-cylinder scavenging, while its high-quality construction ensures durability and longevity.
