1972 Chevy Blazer - The Trail Blazer

Driveway Built, Dirt Ready

By Ken Brubaker, Photography by Ken Brubaker

Mike Aros of Henderson, Nevada, always wanted a ’72 Chevy Blazer, so when he had the chance to purchase one in 2005, he jumped on the opportunity. And so began a three-year wrenchfest that transformed the classic rig into this capable, trail-savvy machine.

Aros, a line mechanic, is no stranger to four-wheel drive, and his motto is “4x or die.” In the early ’80s he purchased an ’82 Toyota pickup, which he proudly owned until it was stolen a year later. In ’93, he purchased a 327ci-powered ’71 Land Cruiser, which he owned for about 12 years. Throughout his years of wheeling in places like Southern California and throughout Nevada, he acquired hands-on knowledge about what works and what doesn’t, and he integrated some of what he learned into the driveway buildup of his ’72 Blazer. Yep, we said “driveway”: “This 4x4 was built in my driveway, almost exclusively by myself. I did have some help with the transmission and transfer case install. The rest was a solo operation,” Aros says.

The entire frame of the Blazer has been sandblasted and painted. Speaking of paint, the cool exterior camo paint job was completed by Aros using $100 worth of Earth Yellow and Earth Red spray paint. Other exterior mods include a Poly Performance 3-inch body lift; a custom rear bumper (made from 2x6-inch, 0.120-inch-wall steel) with D-ring mounts and a 2-inch receiver; custom front bumper/brushguard (made from 1¾-inch-diameter, 0.120-inch-wall tubing) with 2-inch receiver, light mounts for the KC lights, and a mount for the Warn 12,000-pound winch. The Blazer’s fenders were radiused approximately three inches to help make room for the big 42x15.0-15 Super Swamper TSL bias-ply tires mounted on 12-inch-wide steel wheels.

So how does the finished product work? “I wanted this Blazer to work well in rocks and hills, and it does well. All 1-ton axles, lockers, and the 5:1 low-range in the Atlas lets me crawl very well,” he notes. We saw the Blazer in action at last year’s Hump ’N Bump event in Logandale, Nevada, and we’ll concur that the Blazer is indeed a very capable machine.

And that, is a job well done.

  • A tried ’n’ true 350ci small-block V-8 rests in the inner fender-less engine bay. This engine is simple and reliable and features Moroso plug wires, Edelbrock valve covers, a Holley Truck Avenger 670 cfm carb, Patriot headers, and a home-fabbed exhaust with Flowmaster Super 44 mufflers. The ’plant’s cooling system includes the stock radiator, a pair of Flex-A-Lite electric fans, and a Milodon performance water pump. Engine fuel is stored in a Jaz 20-gallon fuel cell and is pumped via a Holley fuel pump through AN-6 braided steel line. Other underhood mods include a Powermaster 160-amp alternator and an Accusump 3-quart Oil Accumulator. Bolted to the engine is a heavily modified TH350 transmission, and it’s ready for hot desert duty with a Flex-A-Lite 8-pass cooler with electric fan.

  • The front suspension is a custom setup that Aros designed. It consists of Rancho 6-inch-lift leaf springs, an Off Road Design Zero Rate kit, 3-inch-longer front spring mounts, lengthened rear shackles, and Rancho RS5000 shocks. The axle is a Boyce Equipment-sourced, ex-military Dana 60 that sports a traction-enhancing Detroit Locker and 4.88:1 gears to offset the large 42-inch tires. And to help point the big meats, there’s a hydro-assist steering system that includes a variety of PSC components including the steering box, pump, reservoir, drop pitman arm, and hydraulic ram. Finally, there’s an Off Road Design crossover steering system to improve the steering geometry.

  • Aros designed the rear suspension, too. It uses 56-inch-long, 6-inch-lift Rough Country springs; an Off Road Design Shackle Flip kit and U-bolt reversal kit; Rancho RS5000 shocks with relocated mounts; and a 1¾-inch-diameter, 0.120-inch-wall traction bar with Ballistic Fabrication rod ends. The 14-bolt rear axle is also a Boyce Equipment-sourced, ex-military unit, and like the front it has a Detroit Locker and 4.88:1 gears.

  • Power is sent to the axles via a 5.44:1 Atlas four-speed transfer case, and it sprouts a pair of Adams driveshafts. The front ’shaft has 1350 U-joints, and the rear has a 1350 U-joint and a 1350 CV-joint. The transfer case is shifted via custom-made cable shifters.

  • The interior of the Blazer is a study in functionality. A custom stainless-steel housing holds five Auto Meter oil-filled gauges that display oil pressure, water temperature, transmission temperature, fuel level, and voltage. MasterCraft high-back suspension seats and five-point harnesses keep passengers comfortable and safe. Speaking of safety, there’s a full rollcage made from 1¾-inch-diameter, 0.120-inch-wall tubing. Other interior mods include a custom center console, an “old” steering wheel, indoor/outdoor carpet, Art Carr shifter, and a Cobra CB. There’s no radio because Aros “likes the sound of the motor.”
