2017 SEMA Battle of the Builders

Build Notes for the Top 12

For many in the custom-car industry, the SEMA Battle of the Builders is a chance to prove that they are among the best. The 2017 competition began with nearly 300 applications from builders representing an elite group of individuals who have demonstrated extreme talent, creativity and craftsmanship in modifying cars, trucks and SUVs. The field was not only the largest to date but was also deep in entries of exceptional quality. This year also saw the expansion of the Young Guns recognition, which shines the light on young, up-and-coming builders in the automotive industry.

SEMA Show Cruise

Automotive YouTubers Michael Nguyen (SmurfinWRX) and David Patterson (ThatDudeinBlue) served as Young Guns judges, joining returning judges RJ DeVera of Meguiar’s, David Freiburger from The Enthusiast Network (TEN), and Fred Williams from Petersen’s 4-Wheel & Off-Road. Many hours of judging resulted in winnowing the field to 12 outstanding vehicles. At that point, the 12 builders themselves convened and scored each entry. Based on their insights, Troy Trepanier’s ’29 Ford Model A Tudor sedan edged out the amazing builds of fellow Top 3 finalists Alan Johnson (’32 Ford Tudor) and Troy Ladd (’36 Packard roadster) for the title.

’29 Ford Model A Tudor

Lead Builder: Troy Trepanier, Rad Rides by Troy, Manteno, Illinois

Displayed: Flowmaster booth

After an intensive inspection by his fellow Top 12 builders, Trepanier’s ’29 Model A was voted the top SEMA Battle of the Builders car for 2017. Information about the build and comments by Trepanier are part of the new “SEMA: Battle of the Builders” TV special now airing on the Velocity Channel, but we can share a few details here.

Troy Trepanier

The engine is a 377ci small-block V8 with Offenhauser 3x2 induction. It’s mated to a magnesium Quartermaster bellhousing, a Legends five-speed transmission, and a modified Halibrand rearend fitted with 3.50 gears. The exhaust is by Flowmaster.

The Model A’s hand-built body, resplendent in custom-mixed Glasurit bronze paint and benefitting from many custom touches, rides on a boxed frame from a ’35 Ford, adapted by adding a custom crossmember. The suspension is via torsion bars damped by Ride Tech shocks, and the tires are Excelsior Stahl Sport radials from Coker. The flowing grille and grille shell were crafted from multiple ’30s Fords, yielding an impressive presence. The interior features a hand-built seat frame and cushions, a bowed headliner, and German square-weave carpet, and it’s finished in hand-tipped Italian leather.

’54 Chevrolet Corvette

Lead Builder: Larry Griffey, Hot Rods & Restorations, Knoxville, Tennessee

Displayed: Hot Rod Industry Alliance booth

Larry Griffey

Griffey’s ’54 Corvette has been intensively customized with body modifications that permit the use of power roll-up windows, larger wheels and tires, wider doors, and a removable hardtop. The car’s fiberglass body was chopped and channeled to make it lower and wider than standard, and it was then painted Soul Red.

Corvette InteriorCorvette

Most of the independent-suspension chassis components are from a C4 Corvette, matched with RideTech coilovers, Baer Brakes and a Speedway Engineering anti-sway bar. The tires are from BFG and are mounted on rear 20x10 and front 18x8 Billet Specialties wheels.

The LS1 V8’s output is enhanced by an Edelbrock supercharger and many upgraded internal components, and the engine compartment was custom designed to cleanly hide wiring and plumbing. The radiator was custom built to fit, and the transmission is a built 4L60E from Atkins & Son Transmission in Knoxville.

The interior was installed by Steve Holcomb of Pro Auto Custom Interiors and features a Lokar shifter, Vintage Air cooling, a Con2r steering wheel, and gauges by Classic Instruments.

'69 Chevrolet Camaro

This first-generation Camaro streetfighter retains a classic Camaro look and feel but is upgraded with late-model features and was executed with exemplary attention to detail. The powertrain consists of a supercharged LT4 6.2L V8 crate engine backed by a T56 six-speed transmission. The Camaro rides on a Roadster Shop Fast Track chassis, and the custom bodywork includes a hand-built front spoiler and side skirts and a custom lower rear diffuser/valance.

’32 Ford Tudor

Lead Builder: Alan Johnson, Johnson’s Hot Rod Shop, Gadsden, Alabama

Displayed: Ford Motor Company booth

Alan Johnson

Alan Johnson’s ’32 Ford Tudor is the result of a four-year project, and as Johnson noted, “There’s not much on the car that we didn’t build from scratch.” The concept was to retain old-school looks but modernize when and where appropriate. Special attention was paid to an instrument design that offers depth and detail, for which Classic Instruments supplied gauges “with that Rolex-watch look.”

The powertrain features a ’57 Ford 312 Y-block V8 that was reworked by racing engine builder Keith Dorton at Automotive Specialists, resulting in an output of about 430 hp. An old Hilborn injector made into a plenum manifold disguises the engine’s electronics. The transmission is a Bowler five-speed, and power is transmitted to the wheels via a quick-change rear end. The suspension uses RideTech components, and the tires were sourced from Coker.

The build team collaborated with Borla when finalizing the intake and exhaust, and the radiator was sourced from Walker Radiator Works in Memphis, Tennessee. The ’32 Tudor runs Royal Purple fluids.

’36 Packard Roadster

Lead Builder: Troy Ladd, Hollywood Hot Rods, Burbank, California

Displayed: Clean Tools booth

Troy Ladd

Six years in the making, the Hollywood Hot Rods Packard roadster looks like it could be a restored classic, but it’s not. The frame is hand built, and the body is about 80% handmade from flat sheets of 18-gauge steel. The art-deco styling theme is dominated by the grille, which opens and closes based on temperature, and the car sports a power hardtop that folds down into the trunk, resulting in perfect-looking lines with the roof up or down.

Troy Ladd CruisePackard Engine

The powertrain includes a supercharged 12-cylinder ’41 Lincoln Flathead with twin Winfield Double D carburetors, and the engine is backed by a Borg Warner T5 and a Winters rearend. The Firestone whitewall tires were sourced from Coker, and the four-wheel independent suspension is adjustable via a touchpad system. Elegance Auto Interiors of Upland, California, executed the tan leather interior, and Mick Jenkens at Mick’s Paint in Pomona, California, handled the Mulholland Merlot PPG paintwork. The audio hardware is from Rockford Fosgate.

Leach Model A

Leach’s Model A stands out for its art-deco finned suspension and chassis, cast-looking components, and a coach-built body. The result combines old-school hot-rod sensibilities with elegant machine work, achieved through 3D modeling and CAD design techniques. It’s powered by a blown aluminum Flathead V8 from Ford rebuilding specialists H&H Flatheads of La Crescenta, California. The engine is topped by twin Stromberg 97 carburetors and is backed by a Bowler C4 automatic.

The body is an original that was restyled with a 6-in. chop and judicious shave and section alterations to permit upgrades such as flush-fit doors, and it was painted by Charley Hutton’s Color Studio in Paleozoic Blue. It all fits on a custom 104-in.-wheelbase chassis. The interior is executed in distressed leather, highlighted by an instrument cluster from Classic Instruments and a one-off steering wheel.

Lead Builder: Mike Markin, Eau Claire, Wisconsin

Displayed: Meguiar’s booth

Graham 97 

Over a period of four and half years, Mike Markin converted a four-door sedan into an award-winning art-deco two-door coupe. In the process, the car was shortened by 26 in., and the fat fenders were modified to emphasize its streamlined appearance. It features extensive chrome accent pieces, many from Advanced Plating, and was painted in PPG Bordeaux Reserve.

Graham 97

The billet wheels shod with Bridgestone Potenza radials were created by Evod Industries. Now referred to as Shark, the Graham is powered by a 600hp, 540ci Chevy big-block V8 that is backed by a 700-R4 automatic.

A dashboard from a ’37 Lincoln highlights the interior. Elegantly redone by Classic Instruments, it now houses the latest Bluetooth-enabled audio components.

'69 Camaro

Master fabricator Jeremy Miranda’s shop, Miranda Built, was founded in 2006 as a design and fab shop capable of correctly reinventing classic cars using modern technology. Miranda’s ’69 Camaro is a good example.

Based on a Roadster Shop Fast Track chassis, the car is powered by a 440ci LSX dry-sump, flex-fuel engine that is backed by a TR6060 transmission. The wheels are bronze ADV1 items, and the massive brake system uses Wilwood components. The front and rear valance and rocker extensions were fabricated from scratch. The drip rails were shaved, and the front and rear glass were flush-fitted.

’95 Porsche 911 Carrera

Lead Builder: Peter Nam, Gunther Werks, Garden Grove, California

Displayed: Meguiar’s booth

Peter Nam 911 Carrera

This unique Porsche is a bespoke rebuild of the Porsche 993 (the last air-cooled 911) that has been modernized with lightweight carbon-fiber wide-body construction. This particular car, based on a modernized ’95 Porsche 911, is built to approximate the capability of the hardcore GT3 RS.

The 4.0L flat-six engine includes all new internals, including Mahle pistons, Camillo rods and a GT3 oil pump. Working with a 7,800-rpm redline, the water-cooled engine produces some 400 hp and 330 lb.-ft. of torque. Engine management is based on a Motec system, and the transmission is a six-speed manual, but with new gear ratios.

Peter Nam Carrera

The exhaust system is valved to permit wide-open operation for track use and offer a more muffled sound for street use. The body and most interior panels are carbon fiber for lightness, so the car weighs in at just 2,670 lbs. It has LED headlights with 3D printed-aluminum housings.

Peter Nam Carrera

Peter Nam is the founder and CEO of Vorsteiner, a company best known as a leader in providing advanced aerodynamics products for high-end exotic sports cars. Gunther Werks is a new company that specializes in using modern technology and is now developing the Porsche 400R Project.

The suspension is based on a twin I-beam front and a four-link rear, with custom King bypass shocks and coil-overs. The rear-end setup features Camburg 4-in. race-series 4130 parts, and Prismatic Powder did the powdercoating on the chassis.

The exterior incorporates McNeil Racing fiberglass pieces, a custom Royalty Core grille, a custom paint job, and a custom overhead light rack that holds Fenix AI lighting. The wheels are Vision Wheels forged bead-locks shod with BFGoodrich Baja T/A tires. The full luxury interior features custom Beard seats, M&M Fabwerx tin work, a Racepak dash and Bentley carpet.

Pettus’ ’63 Corvette is one of three Corvettes to make the Top 12 and one of two C2 Corvettes recognized by the SEMA judges as outstanding. The award-winning restomod, 18 months in the building, is powered by a cross-ram fuel-injected 327 V8 small-block stuffed with upgraded parts and pieces from the likes of Pro Topline, COMP Cams, MSD, Hedman and others.
