As the owner of 13 Revology cars, Mark Pieloch is clearly a big fan of the company.
But even Mark was impressed by the performance of a 1969 Revology Mustang Boss 429 that he drove recently in the grueling 2026 Hemmings Great Race along Route 66.
For Mark, the event was not about beating the 142 rival entrants to the finish line or the prize money. His goal was to demonstrate that a Revology Boss 429 could tackle one of America’s toughest endurance drives, while delivering the comfort, reliability, and excitement of a modern performance car.
From his home in Melbourne, Florida, Mark’s journey began long before the official starting line in Springfield, Illinois.
While most Great Race competitors transported their cars to the event, Mark set himself a larger challenge. Instead of unloading the Mustang from a trailer, he drove it from Key West, Florida, all the way to Springfield before the race even started. By the time the opening ceremonies began, the car already had several thousand miles behind it.
That seven-day drive became the first chapter of an adventure that would eventually cover more than 5,700 miles across America.
From the moment the Pieloch team reached Key West, they realized this wasn’t going to be an ordinary road trip. The striking Boss 429 attracted attention everywhere it went. Cruising slowly along Duval Street in temperatures exceeding 100 degrees, people stopped in their tracks to photograph the car. Tourists shouted questions from sidewalks. Drivers honked their horns, waved, and recorded videos as they passed.
The attention never stopped.
Every lunch stop, overnight destination, and small town along Route 66 brought crowds. As soon as the Mustang rolled beneath the Great Race finish banner each day, spectators surrounded it. Sometimes the attention became almost overwhelming.
“We learned pretty quickly,” Mark joked, “that if you wanted to use the restroom, you’d better get away from the car first. Otherwise you’d be talking for an hour.”
The route tested both driver and machine. From Florida’s 106-degree heat index to the deserts of New Mexico and Arizona, mountain passes above 6000 feet, heavy rain, and dusty plains, the Boss 429 handled every challenge without complaint.
The 429’s heart, a 710hp supercharged Ford 5.0-litre V8, didn’t skip a beat, despite crawling through congested streets with almost no airflow, climbing steep grades, or cruising across high-elevation highways.
Inside, the air conditioning remained ice cold—even in desert temperatures above 100 degrees—and the modern climate control prevented the fogged windows that plague many original classic Mustangs during heavy rain.
For Mark, those comforts highlighted the biggest difference between driving a Revology Mustang and the originals he has owned for decades.
He had previously driven a 1965 Mustang thousands of miles across America multiple times, but those trips came with blistering cabin heat, scorching vinyl seats, and exhausting conditions.
“You get older,” he reflected with a laugh, “and you get wiser.”
The Great Race also showcased the Revology Mustang’s remarkable performance.
As they stopped along the route to capture scenic images, Mark and navigator Curtis Schade often fell several minutes behind their scheduled position. Catching back up required brisk acceleration over steep mountain roads.
The Boss 429’s torquey V8, paired with a six-speed manual transmission, delivered. Whether climbing 12 percent grades or accelerating past slower competitors, the car never hesitated. For Mark, the 429’s performance, especially under duress, proved the car was more than just a pretty face.
By the time Mark rolled across the finish line in Pasadena, California, his original question had already been answered. After more than 5,700 miles of highways, mountain passes, deserts, traffic, and crowds, the Revology Mustang had done exactly what it set out to prove: it wasn’t just built to look like an American icon—it was built to be driven like one.
