METALFLAKE: The Roth Way
Spraying flake isn’t a black art; it’s simply a slightly different medium. It’s no tougher to spray than anything else, although you do have to be meticulous, pay attention to the details and resist the urge to rush. Plus, unless you have a spray booth, it doesn’t matter how well you seal off your chosen spraying area: This stuff will escape and get everywhere.
THE OLD AND THE NEW
The relentless progress of technology is a difficult topic for those of us captivated by the cars and lifestyles of a bygone era. As technology advances at an exponential rate, we now find ourselves clamoring to keep up with the latest and greatest products that simultaneously render many of our old favorites obsolete. Just about the time you figure out how to use your new digital camera and multifunction cell phone, you find out that someone decided it was necessary to combine the two. The struggle to balance the conveniences of modern technology with our nostalgia is especially difficult for many street rodders.
’CUDA HUNT
Craig Hammon is the type of guy who can cherish the best of the old times, while also being able to appreciate the benefits of these new times. This versatility is apparent when one learns not only of his choice of car, but how he came to own it. It seems that Hammon has always wanted a Plymouth ’Cuda. And while this is not an unusual thing in and of itself (we would love to have one, too), when it came time for him to really get serious about buying one, he looked to the Internet. More precisely, Hammon went looking for his dream car on eBay.

The Loss of an Industry Titan
The automotive and motorsports world has lost one of its most influential figures with the passing of Angelo “Junior” Giampetroni. A pioneer, promoter, and passionate builder, Angelo helped shape the hot rodding and drag racing scenes from the postwar boom through the modern era. His impact can be felt not just in Detroit, but across the globe—from gritty speed shops to high-level factory performance programs. Angelo wasn’t just part of the culture—he connected it all together.
From Sweeping Floors to Shaping a Movement
Angelo’s journey began at age 12, sweeping floors and stocking shelves at Gratiot Auto Supply in Detroit. That early exposure to performance parts and customer needs planted the seed for a lifetime of innovation. As soon as he could, he bought a 1932 Ford five-window coupe powered by a 292 C.I. flathead, outfitted with Grancor heads and an Isky cam. It doubled as his daily driver and weekend race car, running over 120 mph at Motor City Dragway and Detroit Dragway. Even then, he wasn’t just building cars—he was living the culture.
Gratiot Auto Supply: Grassroots Powerhouse
By the 1950s, Angelo had become instrumental in transforming Gratiot Auto Supply from a small local shop into a national force. Working alongside founder Bill Toia, he helped expand it to nine Detroit-area locations and a booming mail-order business. In 1969, Angelo launched Detroit Hi Performance, which evolved into Gratiot Auto Mail Order—shipping parts worldwide. He was one of the first in the industry to use TV commercials, print ads, and car show appearances to market speed parts. To bring attention to the brand, he even brought on Linda Vaughn, Miss Hurst, as a national spokesperson. Angelo made sure that no matter where you were in the country—or the world—you could feel a piece of Detroit in your garage.
Iconic Cars and Cultural Reach
Angelo didn’t just sell parts—he helped define an era of performance innovation. He sponsored and developed iconic cars like:
Lil Billy: A rear-engine 1920 T Roadster with a 480 C.I. Buick, clocking 168+ mph and running a 9.30-second ET.
Aggravation: A Hemi-powered bantam dragster built by Al Bergler.
Chevoom: A mid-engine ’66 Chevelle, created with Maynard Rupp.
Both Aggravation and Chevoom earned Riddler Awards at the Detroit Autorama, showcasing Angelo’s eye for performance and presentation. His catalog business shipped performance parts around the world and carried legendary brands like Holley, Edelbrock, Isky, and Hooker.
Bridging the Gap: Angelo at Ford SVO
In the 1980s, Angelo made a pivotal move—joining Ford Motor Company’s Special Vehicle Operations (SVO) as Marketing Director. With his deep aftermarket roots and street-level credibility, he became the perfect bridge between Ford’s corporate engineering and the performance-hungry enthusiast community. At Ford SVO, Angelo played a key role in helping Ford Motorsport Operations (FMO) stay visible, relevant, and respected among racers, builders, and weekend warriors. He brought the authenticity of Detroit speed shops into the boardrooms of Dearborn, ensuring that Ford’s performance parts stayed connected to real-world drivers.
Supporting the Scene and Giving Back
Angelo remained committed to racers and rodders throughout his life. He sponsored legendary teams like Mancini Racing, led by 2018 MMSHoF inductee Ron Mancini. With the Gratiot Auto Supply name emblazoned on cars across the country, Angelo’s influence stretched far beyond the Detroit city limits. He also became a fixture in hot rod media—most famously appearing on the cover of Hot Rod Magazine with Linda Vaughn and the Sprint T roadster.
A Life That United a Culture
Angelo Giampetroni wasn’t just a hot rodder, a businessman, or a marketing mind—he was a connector. From a 12-year-old shop helper to a leader inside Ford, he served as the living bridge between two worlds: grassroots hot rodding and corporate performance. His legacy isn’t just in catalogs or quarter-mile times—it’s in the culture he helped grow, the people he championed, and the brands he brought together. His story is a reminder that true impact comes from passion, vision, and the ability to bring others along for the ride.
