Mike Walden’s Chevy Caprice wagon called “Radio Flyer” was built by Rodney Knocks in Philadelphia, Pennsylvania. Under the hood sits a turbocharged 5.3 L LSx (Gen 4) V8 mated to a TH400 automatic transmission. The V8 makes 780 horsepower to the wheels on C16 fuel tuned by K.P. Tuning. The engine features a stock bottom-end, Lil John’s Motorsport Solutions (LJMS) camshaft, stock truck intake, air-to-water intercooler, S480 turbocharger, and Holley Dominator.
