TRICK FLOW SPECIALTIES SINGLE PLANE
Having never tested the single-plane intake from Trick Flow Specialties, we were excited about getting this one on our test engine. The TFS intake offered solid performance, with peak numbers of 652 hp at 6,900 rpm and 557 lb-ft of torque at 5,300 rpm. Unlike some of the others, this TFS manifold was designed specifically for carbureted LS3 applications, though injector bungs were present. As with many of the intakes, we would like to see TFS offer a version with a 4500 carburetor flange, as this 415-inch stroker certainly responded to additional airflow. The TFS intake offered good average power production and 496 lb-ft of torque at 4,000 rpm.
