THE AUTO BUILDER
Featured
Buxtosaurus Rex
When the owner brought this truck to Buxton in late 04, it was an old farm truck with a straight-six engine, three on the tree and studded snow tires. Buxton began by boxing the frame and adding an IFS unit. With Air Ride Technologies airbags and 2-inch dropped spindles, the front end of the Chevy was able to go very low. In the rear, a Currie Enterprises 9-inch rearend was suspended with ART airbags on a four-link system. Speaking of the rearend, it has been equipped with Strange Engineering 3.73 gears. As the Chevy would obviously come across a few bumps, aluminum QA1 adjustable shocks are used on all four corners. Speaking of the corners, a set of Wheelsmith smoothie wheels adorns this Chevy, giving it a very cool retro look.
PRODUCT SPOTLIGHT: The ProFlex DXI by Advanced Fuel Dynamics
If you’ve got a 2020+ GM V8 truck or SUV and you’re not running E85 yet, you’re leaving power and money on the table. Enter the ProFlex DXI—the easiest, fastest, and flat-out smartest way to slap flex fuel capability onto your rig. No tuning, no ECU unlocks, no headaches—just more horsepower and lower fuel costs in about 15 minutes.
THE HYDROGEN HIGHBOY
Enter Carl Casper, a man best known for building custom cars and promoting his huge custom car show every year in Louisville, Kentucky. Casper has long been a self-thinker and innovator with plenty of experience under his belt, and he was intrigued with the concept of alternative fuels, hydrogen in particular. During our conversation with Casper, he summed it when he said, “I feel many of the solutions will come out of the car guys. I want the mechanical wizards who have taken street rodding and auto racing to the highest levels imaginable to start putting their creativity into alternative-energy systems. I’m putting my money on them. Everyone seems to be waiting for the big corporations to pull us out of this energy crisis, and they tend to forget that from the very beginning of time it’s often the little guy with a shop behind his house who creates the next great idea or invention of our time.”
