Ask our Experts, we're here to help!
You know the recipe: You go to a junkyard, find a Chevrolet or GMC truck that's already seen half a million miles, relieve the poor beast of burden of its LS engine and drag it home. You change out the camshaft, valve springs, and you add a turbocharger, exhaust setup, fuel, and a computer that can take commands without question and voilá, you now have enough power under your right foot to push you to the point of adrenaline overdose. Matt Happel has been pushing this program under the Sloppy Mechanics name for years, and it has become a phenomenon that went from being almost a joke amongst gearheads to a sincere way of life. Don't buy it? You must not have attended a Holley LS Fest, where we've seen this same build setup crammed into just about everything.
Even a Nissan Sentra.
And now, Holley and Sloppy Mechanics have come together to bring you a kit that will bring you a major step closer to turning that thing you dragged out of a well-worn Yukon into a howling, racing demon. What you do with it after that is up to you!
If you have a junkyard 4.8, 5.3, or 6.0 Gen III or IV motor begging for more power, the winner will receive everything they need to transform their unassuming junkyard jewel into a fire-breathing Sloppy Mechanics masterpiece capable of making more than twice as much power as it would in stock form.
