Jeff Thomas of JT Racing screwed together the 331-incher. A 10.5:1 compression JE piston works with H-beam rods and a stroker crank to fill the 0.030-inch over stock block. Bennett Racing ported the Trick Flow High Port heads that wear 2.08-inch intake and 1.6-inch exhaust valves. Not surprisingly, Jonathan Bennett prescribed the custom solid-roller camshaft to work with the 1.6:1 Harland Sharp rocker arms, Comp Cams valve springs, and Lunati lifters. A Jay Nelson-ported Victor 5.0 intake, an 80mm throttle body, a Kook's exhaust system, Hooker mufflers, an MSD ignition, and 38-lb/hr injectors make 409 hp and 368 lb-ft at the rear wheels. With a 150hp shot from the onboard NX nitrous system, those numbers climb to 576 hp and 661 lb-ft. That's how you push 3,100 pounds of Mustang into the 10.20s at more than 133 mph.
