Vortec 5.3L V8 SFI, 4-Speed Automatic with Overdrive, and 4WD. Back in Black! Call ASAP! Don't pay too much for the truck you want...Come on down and take a look at this hard-working 2004 Chevrolet Silverado 1500. New Car Test Drive called it ...the smoothest, quietest, most civilized, best equipped, and most enjoyable pickup truck we've ever driven... It has only been gently used and has VERY low miles. They don't come much fresher than this!
