    We all like to brag about horsepower, but the reality is that torque makes a successful street motor. Torque production is what big-blocks are all about, including this 557-inch Ford monster. Never mind the peak of 615 hp, the torque curve exceeded 650 lb-ft from 3,600 rpm to 4,700 rpm and never dropped below 600 lb-ft until 5,350 rpm.
