Barely a month after we first told you about Callaway's plans for the new Chevrolet Silverado and GMC Sierra, the Connecticut-based tuning shop has shown its first completed model. Using a Silverado, Callaway has fitted an Eaton TVS supercharger and developed a new calibration for GM's powertrain management system.

Improvements aside, we still haven't been told just how much more engine power is is available. Callaway says that information "will be released very soon." Initial targets for the 5.3-liter V8 saw a bump to 450 horsepower, up from 355 hp. If you just can't wait to snap up one of the supercharged trucks, authorized Callaway dealers are accepting orders on the Silverado and Sierra Crew Cabs with the 5.3-liter, supercharged V8 right now, and will expand ordering to the Extended Cab and Standard Cab models soon. Packages start at $17,395.

While GM's smaller V8 is about ready to go, Callaway isn't ignoring the bigger powertrains. It's taking the know-how from the 5.3-liter project, particularly with the engine management software, and is applying it to GM's upcoming 6.2-liter, V8-powered vehicles. By the end of the year, the Callaway Sierra and Silverado will be available with the 6.2, for those that need even more thrust. And of course, we can expect the highly anticipated Callaway Corvette to arrive by the end of the year, as well. Scroll down for the official press release from Callaway.Continue reading Callaway debuts first supercharged 2014 Silverado
