Capping off the front end is an RKSport fiberglass hood. This ram-air hood transforms the look and is fully functional to help pull cool, fresh air to the engine. Under the hood, the stock 6.0L Vortec V-8 remains relatively unmodified and provides reliable service for Jimmy’s adventures on-road and off the beaten path. The stock 360hp/380–lb-ft performance numbers are bumped up thanks to an Airaid intake and Gibson dual exhaust system. TCD Performance in Warren, Ohio, built a custom tune for the DiabloSport programmer to maximize the engine output.
