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.
PRI 2025 New Product Round-Up
The 2025 PRI Show just tore through Indianapolis, and if you weren’t there, you missed a full-throttle showcase of racing tech that doesn’t mess around. Builders, racers, and gearheads packed the floor, and the energy was absolute chaos—in the best way. The products? They didn’t whisper—they slammed onto the scene, sharp, loud, and ready to make your ride better, safer, faster, meaner.
Let’s Look
The growing popularity of nostalgia and rat rods, along with the aging of street rodders, has meant the rebirth of vintage engines. Rocket Oldsmobiles, Buick nailheads, Y-block Fords and Chrysler Hemis are being chosen over the “bellybutton” Chevrolet small-block. Even some small-block Chevrolet engines are getting old-time flavor by using generators–some of which have been internally modified as alternators–early blocks and heads, three-deuce setups and even adapting Oldsmobile valve covers to look like something they are not.
Rad Win by Rad Rides
We knew this one was special the moment we first spotted it at the 2024 Grand National Roadster Show. Now it’s official—the 2025 SEMA Battle of the Builders Presented by Mothers Polish has crowned Troy Trepanier of Rad Rides by Troy as the best overall builder of the year with
Coast to Coast Cool
Part of the rarity of this car comes in the fact that this is one of the first 12 original Coast to Coast ’39 Ford Convertible bodies to be built. Since that time, a second-generation body has been developed, and while some changes have been made, the overall look is
CLARITY OF THOUGHT
You can’t blame Dean Sears for feeling a little confused about his love for cars. You see, he’s spent the past nine years as the head of Sport Trucks by Dean in Moorpark, California. His first car, in fact, was a truck. Well, sort of a truck. It was a
AMERICAN BEAUTY
From a distance, this roadster appears to be from another place, far from American shores, as much as from another era. On closer approach, the Borrani wire wheels conjure thoughts of European heritage, although the shape borrows as much from past Indy roadsters and Sprinters as it does from the

PRODUCT SPOTLIGHT: Cam Covers for GEN/3 Coyote from Pyramid Optimized Design
You can bolt all the horsepower in the world under your hood, but if that engine bay looks like a tangle of plastic and wires, it’s still missing something. That’s where the new GEN/3 Coyote Cam Covers come in — from the same team at Pyramid Optimized Design that scored
TAKE A WALK ON THE MILD SIDE
For many hot rodders, the word “custom” conjures up images of chopped, channeled, molded and frenched cars with wild metalflake paint jobs. Such radical customs no doubt helped define the custom movement of the 1950s, along with such phrases as “if it don’t go, chrome it,” but in virtually every
BEYOND THE ENVELOPE
There’s no question that this ’68 Camaro pushes buttons, limits, and envelopes. This unique creation even pushes our understanding. It’s part nostalgia, part Blade Runner, brought together through a great deal of thought, creativity, and sheer talent.
PERFORMING ARTS
Certain cars are stars. The ’57 Chevrolet Bel Air found itself in starring roles since the first car rolled off the assembly line. From its art deco fins and side trim to its potent 283, the car was an instant hit. Fans of the 1957 continue to follow the car,

NO. 1 of 25
Most car guys know all about rare cars, and this certainly is one of the rarest Ford Mustangs on the road. In what some may consider an odd collaboration, Carroll Shelby International Inc. and celebrity customizer West Coast Customs (WCC) have teamed up to produce a line of limited-edition high-end 2006 Ford Mustangs. Starting with only 25 stock 2006 Ford Mustang GTs, the Shelby/West Coast Customs team has a solid foundation on which to build, and build it did.
PRODUCT SPOTLIGHT: Canton’s GM LS1-LS6 5-5/8″ Deep Front Sump Road Race and Drift Pan
We here at The Auto Builder understand that when it comes to performance, every component counts. That’s why the Canton Racing Products GM LS1/LS6 Front Sump Road Race and Drift Pan has earned a top spot on our must-have list for any serious gearhead looking to elevate their game.
’69 Camaro Update
The late ’60s was a good time for automobile enthusiasts everywhere. For Chevrolet specifically, it remains a time when the company produced vehicles that are among the favorites of Bow Tie aficionados. Who wouldn’t want a ’67-’69 Chevy Chevelle, Nova or, of course, the ever-popular Camaro? The design of these vehicles, and many others from that era, has stood the test of time, and car manufacturers today are even reverting back to the styling cues of these classics when designing modern production cars.

Two-Hour Tech
Improving your S197 Mustang doesn’t have to be an arduous affair. You’re supposed to enjoy working on your car, RATHER than dreading getting off work because you “have” to wrench on the Ford. With that attitude in mind, we recently spoke with Al Kamhi, of Control Freak suspensions, to get his advice on what enthusiasts could do to further the concept of upgrading a Mustang in just an hour or two. But there’s a catch: the upgrade had to make a real difference in the car’s performance.

CIMTEX RODS SUPER CAMEO: PART 8
In part seven of our Cimtex Rods Super Cameo Buildup series, we covered the installation of our Stainless Works four-tube ZR1 headers and Cimtex Rods-fabricated 3-inch custom exhaust system, as well as the fabrication and installation of our Cimtex Rods-constructed 22-gallon fuel tank and the accompanying MagnaFuel fuel system. Now we’re going to cover the mockup of our Powerdyne BD-11A SilentDrive twin supercharger system. But first let’s digress and take a look at the big picture. One of the key criterion in our Cimtex Rods Super Cameo buildup was to elicit that all-important “wow” factor throughout the entire series. When it came to the engine, we didn’t want to install just any old run-of-the-mill, multi-carbureted GM small or big block, much less a late-model GM crate engine straight out of the catalog. Going in we figured that the Cimtex Super Cameo powerplant should be something special.
