Starting with a production 460 block stroked to 557 cubic inches, this build combined CNC-ported Trick Flow A460 heads, a COMP drag-race roller cam, and a dual-Dominator tunnel ram to produce 931 hp and 757 lb-ft of torque - all naturally aspirated.

Built around a Speedmaster 4.50-inch stroker crank and rods, this 557-cubic-inch Ford big-block topped with Kaase P-51 heads delivered 754 hp on pump gas and 1,014 hp with a 200-hp nitrous shot.
