Tucked well within the chassis tubing are the powerplants. A Ford engine built by Pro Power motivates Carl's truck and engine displacements range from 380 to 410 cubic inches, depending on class restrictions and truck weight. From this, the team derives over 800 horsepower and 700 lb-ft of torque. The 442 cubic inch Dougan's Chevy motor in Cameron's truck pumps out about 770 horses along with 670 lb-ft of torque. Both trucks use heavily modified GM Turbo 400 trannies and cooling chores are handled by radiators and fans behind the cab of each truck.
