John has chosen Holley's 4150 750-cfm carburetor atop a Weiand X-celerator single-plane manifold. As you were taught in Engine Basics 101, a single-plane manifold makes all kinds of high-end horsepower, but it is not an all-around street manifold. John also chose a Plenum Divider Kit (PN 128351) for this manifold. Torque isn't stellar under 4,000 rpm, but above 4,000, get out of the way-374.7 lb-ft at 5,300 rpm, with 408.8 hp at 5,900 rpm. Not a broad powerband, but plenty at full throttle above four grand on the dyno. View Related Article
