Yes.

Yes. Yes. Yes.

Flat black with a perfect body, a massive Borg Warner S500SX 91mm turbocharger, and a stance that could kill. It's from Houston, Texas too, so you know it runs faster than it looks, even if it looks like a 9-second truck. How does 9.01 at 161-mph sound? Oh, yeah, that'll happen with 1,250-rwhp and 980 lb-ft of torque on tap. And thanks to the custom four-link out back, it'll run a 1.32-second sixty, on the way to blowing the doors off of race cars on a regular Saturday night. What we're looking at here is more an evil super villain than a street truck, but thanks to the crew at Fastlane, it's an '03 Silverado that's capable of splitting wigs, taking names, and hanging out at late night gatherings in seedy places.

Power, which this truck has in droves, comes from a familiar source. A Chevrolet Performance LSX block holds the hard parts together, which was machined to a 4.100-inch bore by Fastlane Machine prior to assembly. Inside those holes sit eight Wiseco dished pistons, which rest atop a set of GRP aluminum connecting rods and a Callies 4-inch stroke crankshaft. If you're quick with math, you already know that this is a 418 cubic-inch beast, which may seem small to some, although the power numbers and track times would prove otherwise. Atop the 418 is a set of Trick Flow Specialties heads, which sport a set of 2.100-inch and 1.600-inch intake and exhaust valves. Fastlane didn't care to share the exact intake runner specs, or the flow numbers for those beauties, and only listed the camshaft as a solid roller from Bullet Racing Cams with "secret" specs. When you're truck looks and runs like this, you're going to keep some tricks up your sleeve…

Obviously, the engine alone isn't making enough steam to lay down 9-second e.t.'s, so it should come as no surprise to learn that this truck gathers and compresses massive amounts of air from a front-mounted 91mm Borg Warner turbocharger. And by "no surprise," we mean no surprise, as the impeller literally sticks out of the grille for a no nonsense look. A set of stainless turbo manifolds run exhaust to the turbo, which expels spent gasses out a massive 5-inch downpipe. Four-inch aluminum tubing runs compressed air to the PTE2000 air-to-water intercooler before eventually slamming all 18 pounds of boost into the Edelbrock cast intake manifold. Big boost requires big fuel, and this Houston rocket ship runs a set of 160 lb-hr injectors in that intake manifold, fed by a Weldon fuel system at 65 pounds of base pressure.

The rest of the drivetrain is what we might call "Houston stock," with a beefed up Powerglide feeding a Moser 9-inch rear end stuffed with 3.73 gears. The 4500-stall helps get the large turbo up on boost, and the 1.32-second sixty-foot times prove just how well the drivetrain combination works. Of course, power is nothing without traction and the sticky Mickeys rely on a custom four-link, Jerry Bickel sway bar, and a custom wishbone to hit the tires just right. We're not sure that race car stuff was really on the list for this build, but to keep everything legal and on the up and up, Fastlane outfitted the monster with all of the SFI legal goodies one would expect, including dual parachutes, a proper roll cage, harnesses, seats, and fire suppression. The wing helps keep the truck planted at speed, which must be an interesting ride, to say the least.

How does it handle? "It's a truck, it doesn't handle!" But, when you're going that straight for that short of a time, you don't need to handle very well. And this Silverado is fast, proving it with both time slips and head-to-head racing. In fact, Fastlane recently won both the "fastest LS truck" and "fastest truck on the property" awards at the San Antonio LS truck shootout with a 9.01 at 160-mph run. When asked what Fastlane likes most about the truck, the team simply stated the "sinister looks and beating up on race cars." Yeah, we'll gladly take that answer, as our favorite parts are also the flat black exterior and the race car speed in a street truck body. But, that's typical Fastlane for you… building them faster and faster by the day with the style and power to back it up.
