Restored 1972 Chevy K5 Blazer Gets 525-HP LS3 Power and Modern Luxury

This ’72 Chevy K5 Blazer just got a mind-blowing makeover, morphing from a rough-and-tumble relic into a show-stopping beast while keeping its old-school soul. The Riverside gearheads at Rock Bottom Off Road threw everything at it—modern muscle, luxury comforts, and serious off-road chops—creating something that’d make even a NASA engineer whistle in appreciation.

Under the hood? A fire-breathing 6.2-liter LS3 V8 pumping out 525 horses, teamed with a bulletproof 4L80E tranny and Atlas transfer case. Power hits the dirt via rebuilt 8-lug axles with Detroit’s trick Truetrac diffs front and rear, meaning this rig laughs at mud, rocks, or your sister’s wedding driveway.

Suspension? Radflo coilovers with remote reservoirs jack it up 4 inches while keeping the ride tight. Those gnarly 37-inch BFG mud-terrains on 17-inch KMC Grenades aren’t just for looks—they’ll claw through anything. And thank Wilwood’s hydro-boost brakes for stopping this vintage brute like a modern supercar.

Outside, it’s pure nostalgia: black-and-white two-tone paint, that classic double-wall hardtop, and a cage tough enough for family road trips or rolling down a mountain. Inside? Swanky leather and Alcantara, Vintage Air keeping things chill, Dakota Digital gauges, and a RetroSound stereo—because even legends need decent playlists.

Oh, and the cherry on top? A custom dual exhaust, polished aluminum radiator, and Chevy-branded valve covers. Fresh out the shop with barely 800 miles, it’s basically new-old stock.

What you’ve got here is the unicorn of restomods—a truck that’ll turn heads on Rodeo Drive one day and eat Moab for breakfast the next. If you dig heritage with a side of horsepower, this K5’s rewriting the rulebook.
