The term “sleeper” was probably invented by the first guy who got his doors blown off by an unassuming automobile with more horsepower than should be possible. These days, there is no limit to what kind of car can be a sleeper, from 700-horsepower Camry’s to turbocharged Festivas. And the rougher it looks, the faster the sleeper, or so it seems.

That could explain why Sean Whitley’s 1970 C/K pickup, with a license plate like “ZZZZZZ,” you know there’s got to be a lot of power under that ugly hood. How does a nitrous-injected 502 big block sound? Sounds like a Corvette and Mustang killer to us.

Sean is the inventor of “Pimp Juice,” a traction compound agent that also creates bigger burnouts than usual. But the real story is the “OKC Farm Truck,” which Sean keeps purposely rough in order to keep opponents in the dark. It’s also quite the draw, once people figure out that this is one fast farm truck.

Fast it is, clocking in times around the mid-10’s, which ain’t too shabby for a beat-up old pickup. Or a Bugatti Veyron. All told, the Farm Truck makes around 830 horsepower, packs fat tires, and a whole heap of attitude. Make sure you check out all their videos to get an idea of how fast this truck really is.
