The latest GM-powered vehicle to hit the Hoonigan Burnyard is a K5 GMC Jimmy with a built 572 cubic-inch Big Block sitting under the hood.
The Hoonigan Burnyard, for the uninitiated, is a small section of asphalt that has been cordoned off by the automotive media collective so their guests can perform burnouts and drifts in relative safety and security. We’ve seen all sorts of high-horsepower GM vehicles do their thing at the Burnyard, from an LS-swapped Chevy C10 to an 800-horsepower Pontiac GTO, but this K5 GMC Jimmy is a bit of an unexpected sight in this setting. With a high ride height, off-road tires and automatic transmission, this certainly doesn’t seem like it’d be a great choice for burnouts – but what’s under the hood changes everything.
While a stock K5 GMC Jimmy would have absolutely no business being at the Burnyard, this particular one has a 572 cubic-inch Big Block built by Smeding Performance sitting out front, which makes roughly 733 horsepower and 733 pound-feet of torque, according to the owner. Power is sent to all four wheels through a reinforced 4L85E transmission built by Gearstar and stock axles. The Jimmy is otherwise mostly stock, apart from a set of KMC 444 beadlock wheels and off-road tires. It’s even running stock brakes at the moment, although a big brake upgrade bit from Baer is on the way.
With 733 horsepower under the hood, this GMC Jimmy has no problem smoking all four of its tires at the Burnyard. We were concerned this off-roader would flip over with the way the owner is wheeling it, but thankfully it remains right-side-up throughout the video. As Hoonigan says in the video description, if you didn’t think something this big could dance, hit play and prepare to be proven very wrong!
