There’s an art to building a good sleeper. Break it down, and there are two essential elements in play – first, it’s gotta look normal, even commonplace. Factory components, no exterior modifications, nothing to suggest anything out of the ordinary. Second, it’s gotta be fast, with stupid amounts of power and a quarter-mile time that’ll embarrass high-dollar sports cars. This Chevy Silverado HD ticks both boxes, and now, it’s up for sale.
This particular Chevy Silverado HD is a 2500 model from the 2008 model year, and at first blush, there’s not much to it. We see diamond liners for the bed rails, a few stickers in the rear window, a repainted rear driver’s side fender, and a chrome grille treatment, but that’s about it.
That said, if you look closely under the passenger-side wheel well, you’ll find what appears to be some new turbo piping peeking out from the fender liner – red flag number one for anyone looking to challenge this Chevy Silverado HD to a race.
It’s the same story in the cabin, where we find clean upholstery and shiny trim bits. Take a closer look though, and you’ll notice some boost gauges and a tuner monitor near the A-pillar.
All told, there’s very little to suggest just how much firepower this 2008 Chevy Silverado HD is packing – that is until you open the hood.
Lurking behind that polished chrome grille is a completely rebuilt 6.6L V8 turbo-diesel Duramax engine, which now delivers a claimed 1,000 horsepower at the wheels. To make that monster output possible, the ‘eight is stuffed with Mahle forged pistons and Carrillo rods, as well as a chromoly forged cam and crank. There’s also dual CP3s, Stage 2 reworked heads, high-flow up pipes, and tubular headers. All the EGR and smog equipment was removed. Making the boost is a Garrett GT47 and HTT66 compound turbocharger setup.
The seller says this Chevy Silverado HD was built for racing, and is not intended as a daily driver. Either way, there’s no check engine light, even without the smog stuff. Now, it’s up for sale in San Luis Obispo, California, listed at $45,000 with just 24,000 miles on the clock
