Heavily modified LS3-powered K5 Blazer offers vintage looks, off-road performance, and modern luxury in one bold package.
A head-turning fusion of vintage design and modern engineering is hitting the auction block with the debut of “Moab,” a fully customized 1971 Chevrolet K5 Blazer that promises to perform as well off-road as it does on the show floor.
Built around a modified Gen IV LS3 engine mated to a GM 4LE automatic overdrive transmission, this lifted Blazer pushes serious performance with a 2,600-rpm stall converter, F.A.S.T. intake, Precision-Flow injectors, and a Granatelli Motorsports throttle body. Ceramic headers feed a hand-built dual 3-inch stainless exhaust system, all combining for potent output with a distinctly modern roar.
The drivetrain retains the original NP-205 transfer case, while both axles have been upgraded with 4.11 Eaton posi-traction units and custom-painted B&M differential covers. Suspension duties are handled by 4-inch lift soft-ride springs, Fox 2.0 remote-reservoir shocks, and a BDS dual-opposing steering stabilizer system, ensuring both comfort and capability on rugged terrain.
Wilwood brakes with dimpled and slotted rotors provide confident stopping power, while Hydroboost-assisted steering—featuring PSC components and a quick-ratio gearbox—offers precise handling. The K5 rolls on unique 17-inch billet aluminum wheels styled after vintage 10-hole GM Rally wheels, wrapped in 35-inch BFGoodrich All-Terrain K2 tires.
Inside, the Blazer blends retro charm with refined upgrades: a 2016 Silverado center console integrates USB ports and a 1,500-watt Blaupunkt sound system, while Dakota Digital VHX gauges, power windows, and a RetroSound stereo head unit bring high-end function to the classic dash. Upholstery, carpet, and weatherstripping have been refreshed, maintaining period-correct aesthetics with a modern touch.
Finished in Dupont black over a largely original steel body, “Moab” reflects years of thoughtful engineering. With its aggressive stance, durable underbody coating, and NOS touches like a Hickey Enterprises shifter handle, it stands out as both a serious off-road contender and a collector-grade SUV.
This meticulously built K5 isn’t just for show—it was made to be driven.
