17 Reaching the goal of 800 hp required increased displacement combined with proper attention to the big three. The Kaase P51 heads were teamed with a single-plane intake, Holley Dominator carb and aggressive Crane roller cam to produce a stout 557 stroker. With all components working together to optimize power production, the 557 stroker belted out 833 hp at 6,800 rpm and 712 lb-ft of torque at 5,600 rpm. This represented a jump of 224 hp and 155 lb-ft of torque over the modified 460 we tested back in part two. Torque production from the sizable stroker exceeded 650 lb-ft from 4,300 rpm to 6,700 rpm.
