Performance: Fastlane Chevrolet 427SS Silverado
GM'S Concept Is Now Reality
Back at the end of 2006, General Motors showed a cool concept truck at the Specialty Equipment Market Association show in Las Vegas. Called the Silverado 427, this concept had a lowered suspension and new styling cues above and beyond those of the Silverado SS including 22-inch wheels and was powered by the same GM Powertrain 7.0-liter LS7 small-block V-8 as you would find in the Corvette Z06. Sad to say, GM never made this truck available to the public, but that isn't the end of the story.
Fastlane, a company that has built musclecars and trucks for nearly 15 years, is now building its version of the Silverado 427, which the company calls the 427SS Silverado. According to the company, these trucks will be sold at select Chevrolet dealerships.
There are three different levels of truck you can get, depending on how much you want to invest, and each of them is given an individual serial number. The first level is an appearance package, which comes with a Ram air hood, color-matched grille, front bumper cover and color-matched rear bumper, body cladding, tonneau cover, and custom badges. It also has a lowered suspension, custom side-exiting exhaust, and 10x22-inch chrome wheels with 305/40R22 tires.
The next level up is the 427SS package, which sports everything in the appearance package, plus the performance combination that makes this truck most like the original Silverado 427 concept. The source of power here is a custom-built 7.0-liter, 500-horsepower LS3 engine. It has forged pistons, a custom-ground camshaft, Callies crankshaft, cold-air intake, computer calibration, H-beam connecting rods, and stainless-steel headers.
The engine is backed by a custom-built transmission and an upgraded driveshaft. The third level is one that is likely to come to Fastlane in the near future. We don't know too much about this one, but Fastlane has said the LS9 engine will soon be offered in the 427SS.
The LS9 is the engine that powers the Corvette up to 2010. It's a supercharged 6.2-liter V-8 with 638 horsepower and 604 pound-feet. We'll have to wait and see what Fastlane does with that.
