Driveway Built, Dirt Ready

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.

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.
