While the K5 Chevy Blazer is an absolute icon when it comes to off-roading, it has plenty of potential in other automotive scenes as well. In fact, with the right combination of parts and know-how, this old-school SUV can even be a performer on the race track. Proving the point is this fully customized 1970 Chevy Blazer, which is now rocking the road course with a high-powered supercharged LS3 V8.
Recently featured by the folks at AutotopiaLA, this 1970 K5 Chevy Blazer belongs to Hondo Miller, president of the Laid-Back apparel company. If you’re familiar with Laid-Back, it should come as no surprise that Miller is a true automotive enthusiast, and his K5 Blazer follows through on that as one of the wilder builds out there.
As the story goes, Miller’s Chevy Blazer build started in 2018. The original vehicle was rescued from a trailer park in Montana and was in really rough shape. Now, this thing is completely modified from tip to tail, and can be found ripping it up on the drag strip, autocross, and road course, setting some surprisingly quick times in the process.
To that end, this Chevy Blazer now rides on a SpeedTech chassis. Interestingly, SpeedTech developed its original K5 chassis prototype using Miller’s SUV. Under the hood, we find a 6.2L LS3 V8 built by JDP Motorsports and topped by a 3.0L Whipple supercharger. With E85 fuel onboard, peak output is measured at 737 horsepower at the wheels. On pump gas, output drops to 650 horsepower. A Tremec TR-6060 six-speed manual transmission and triple-disc clutch harness the go, directing it to a Dutchman rear end.
Of course, the whole thing isn’t exactly lightweight – in fact Miller estimates his Blazer tips the scales at 5,000 pounds.
“It grips and rips, you know?” Miller says.
Indeed. Check out the full build right here:
