Under the Power Wagon’s hood is the standard-issue 5.7L Hemi V-8. It remains mostly stock with the exception of a K&N cold air intake and a 3.5-inch-diameter exhaust system with Flowmaster muffler. It gets amperage from a pair of Optima YellowTop batteries that are controlled by an isolator system. Power is routed through the stock 5-45RFE five-speed automatic transmission, which is equipped with a B&M SuperCooler to help keep its temperature in check.
