But that’s only in the morning. Besides, aren’t you supposed to be making breakfast for somebody?
That’s the funny thing about well-intentioned plans, much like Bubb Rubb and Lil’ Sis of yesteryear going “WHOO WHOO,” things never quite work out the way they were intended. The whistle tips that were meant to just be a fun little add-on for exhaust audiologists became a massive hassle for those whom were not so inclined.
Chris St. Aubin and his 2004 Silverado SS can clearly relate. We could jump right in and tell you that Chris, his wife, and his family, had a blissful build of a crazy wicked four-wheel drive (AWD – Ed.) truck that went off without a hitch, and now he can move on with his life completely fulfilled. I could tell you that, but that really tugs at our ethical underpants and really gives us snarling integrity wedgie. Chris told us long and twisted tales of bad engine deals, blown up parts, and a lot of broken relationships that finally culminated into what you see before you.
But, we digress. Chris being a car customizer, is used to the daily car grind, and decided that he wanted, no, needed something with all-wheel drive and of course it had to be a truck. “After adding a cold air kit and a custom PCM tune I moved onto the audio and interior. From there it just kind of snowballed into ‘what can I do next?’”
Knowing full well that these trucks weren’t exactly freeway fliers off of the showroom floor, Chris understood that he had his work cut out for him. Not satisfied with simple bolt-ons, Chris gave his friends over at TPIS a call to completely recreate his Silverado SS. Starting with the perfect platform to build upon, the 6-liter LQ9, Chris and the crew at TPIS set to work to punch out the 364 ci. mill to a 408-cube powerhouse. In typical hot-rodder fashion, more was never enough.
Boost was in order, and initially, Chris was looking at aftermarket turbo kits when he fell into a great deal on a D1SC ProCharger. Throw that bad boy on top of the well-built 408 cubic-inch stroker LS variant, and you have a deadly combination of roughly 800 horsepower and 765 foot-pounds of torque at all four wheels!
Even with the massive curb weight, Chris is fully confident that this truck will lay down an 11-second pass at his local dragstrip – which will put it right along side some of the fastest production cars of today! Not bad for a daily-driven pick-em-up.
We asked Chris for a demonstration of the power in the form a killer burnout, but Chris politely declined, and we quickly remembered that being as how the Silverado is all-wheel drive, it was pretty much an impossibility. He told us that, “it’s one thing to do a burnout with a rear-wheel drive car where you can at least keep the front tires planted but that it’s a whole ‘nother animal when you get all four wheels cherry red.”
Chris continues, “My wife calls it our ‘5th daughter,’ and the amount of attention we get [with this truck] is just astounding. We really love seeing the spark in the kids’ eyes when they see her as well! It really makes all the hard work and attention to detail worth it.” The name seemed fairly appropriate too, since we could hear the truck coming from several blocks away prior to our shoot. See that custom cut hole on the hood? It isn’t just to help announce his arrival; it helps dissipate a fair amount of heat created by the stroked LSx residing under the hood. Contrary to popular belief, these Sillverados don’t have that much room between the frame rails, as most of the older trucks did, so it’s a tight fit. “I had a custom engraved and molded plastic cover made for the hood, but it held in too much heat when I got on it,” Chris went on give us the rationale for his custom cut hood scoop.
Thankfully, whistle tips are gone off the market so our ears can take a break, but Chris most likely isn’t. “We still have a few ideas and maybe some future projects but we’re happy with the truck…. for now!” WHOO, WHOO!
