SUREFOOTED MUSTANG

VALUABLE LESSONS
Building an engine at home is exactly what you make of it—your first experience could be a good one if you choose to do it the right way, or it could be a bad one if you take short cuts along the way. As cheesy as it may sound, with engine building, you determine your own destiny with how you go about the build. Buy the right parts, talk to the right people and you may just have a long-lasting engine that puts a smile on your face every time the loud pedal hits the floor. Buy junk parts and think you know it all from the get-go and you’re looking at a big disappointment when it comes time to fire that bad boy.

SMOKIN’ CAMARO
We’ll call Cho’s efforts a modern retro. Much like old heavy-metal bands, classic metal has a timeless appeal, but there’s more—lurking beneath the classic sheetmetal is newfound power that will appeal to both schools of thought; purists will appreciate the clean lines and fastidious restoration, while performance mongers will be delighted to know that the original small block was scrapped in favor of a big block.

MONEY-SAVING, BIG-VALVE PERFORMANCE UPGRADE
You can’t throw a stone these days without hitting an aftermarket aluminum cylinder head. They perform as good or better than anything the factories put out, and then some. They are much lighter than iron heads, and they’re now extremely affordable. Thanks to competition in the aftermarket, it could easily be said that for the performance and price benefits of a new set of aluminum heads, why would anyone bother refurbishing a set of iron castings?

TRI-FIVE FEVER TAKES OVER BOWLING GREEN
Inside the 11th Annual Tri-Five Nationals at Beech Bend Raceway Park
For three days, Bowling Green, Kentucky, became the center of the Tri-Five Chevy universe as the 11th Annual Tri-Five Nationals rolled into Beech Bend Raceway Park, August 13–15, 2026.
Presented by Classic Performance Products, the annual gathering brought together an incredible assortment of 1955, 1956, and 1957 Chevrolets from across the country. Bel Airs, 150s, 210s, Nomads, Cameos, Corvettes, wagons, sedans, convertibles, gassers, customs, and full-blown pro-touring machines filled the historic grounds, once again proving that few chapters in American automotive history inspire the kind of enthusiasm generated by Chevrolet’s legendary Tri-Five years.
Three Years That Changed Chevrolet
The Tri-Five Nationals celebrates a remarkably short—but enormously influential—period in Chevrolet history.
Introduced for 1955, Chevrolet’s completely redesigned passenger-car lineup brought fresh styling, improved engineering, and the debut of the company’s new small-block V8. The design continued to evolve through 1956 before reaching perhaps its most recognizable form in 1957.
Each model year developed its own identity. The clean, restrained lines of the ’55 Chevy gave way to the distinctive full-width grille and side trim of the ’56 Chevy, followed by the fins, chrome, and unmistakable attitude of the ’57 Chevy. Together, the three years became enduring symbols of 1950s America and some of the most popular platforms ever embraced by hot rodders and custom-car builders.
More than seven decades later, their influence remains impossible to miss.
Every Style of Tri-Five Under the Sun
Part of what makes the Tri-Five Nationals so impressive is the sheer variety found within a gathering devoted to only three model years.
There were carefully restored examples wearing factory colors, original-style wheel covers, and period-correct interiors. Nearby, traditional customs sat low over whitewalls and polished trim, recalling the boulevard cruisers of the 1950s and ’60s.
Then there were the modern interpretations—Tri-Fives riding on contemporary chassis systems with oversized brakes, coilover suspension, fuel-injected power, custom interiors, and wheels large enough to reveal every carefully finished component underneath.
The event also attracted its share of gassers, drag cars, weathered survivors, homebuilt cruisers, and machines that have been driven and enjoyed for decades. Some arrived as immaculate showpieces, while others proudly displayed the stone chips, worn upholstery, and road-earned character of cars that were never meant to spend their lives parked under covers.
That mixture is a big part of the event’s personality. The Tri-Five Nationals isn’t limited to one interpretation of what a ’55, ’56, or ’57 Chevrolet should be. Factory-correct restoration, traditional hot rod, radical custom, pro-touring performance, and well-used driver all have a place at Beech Bend.
Show Field Meets Drag Strip
Beech Bend Raceway Park provides a setting few conventional car shows can duplicate.
The sprawling grounds offer plenty of room for rows of show cars, vendors, builders, manufacturers, and the event’s extensive swap meet. At the same time, the adjacent dragstrip allows owners to do more than simply polish their cars and park them for the weekend.
Throughout the event, Holley Drag Racing kept the track alive with competitive racing and fun runs. Everything from vintage-style gassers to seriously quick street machines had an opportunity to stretch its legs, filling the air with tire smoke, race fuel, and the unmistakable sound of Chevrolet horsepower.
That combination of show-field craftsmanship and quarter-mile action gives the Tri-Five Nationals an energy all its own. One moment, spectators can be studying paintwork, panel gaps, and engine-bay details; the next, they can watch another Tri-Five launch from the starting line.
The Search for Parts and Inspiration
For owners in the middle of a project, the vendor area and swap meet were attractions in their own right.
New, used, reproduction, and hard-to-find original components gave builders an opportunity to search for the pieces needed to keep their projects moving. From trim and sheetmetal to suspension, brakes, steering, cooling, and modern performance upgrades, the event brought much of the Tri-Five aftermarket together in one location.
Just as valuable was the inspiration found throughout the grounds. With so many approaches to the same basic cars gathered together, the Nationals offered an almost endless supply of ideas. Paint combinations, wheel choices, engine installations, interior treatments, and subtle body modifications could be studied on actual finished vehicles rather than imagined from a catalog or computer screen.
For anyone planning a Tri-Five build, Beech Bend may be one of the most productive places in the country to spend a weekend.
More Than a Car Show
The Tri-Five Nationals has grown into more than a gathering of desirable Chevrolets. It has become an annual reunion for the people who preserve, build, race, and drive them.
Old friends reconnect beneath tents and beside open hoods. Builders trade ideas. Owners share the histories behind their cars. Families walk the grounds together, often introducing a new generation to vehicles that may have been part of their own family stories decades earlier.
The awards program—including the Lokar Top 25 and the coveted Tri-Five of the Year “Fin” Award—recognizes some of the finest craftsmanship at the event. But trophies tell only part of the story. Outstanding cars could be found in nearly every row, including plenty of honest drivers and homebuilt machines that captured attention without ever entering the formal competition.
The Tri-Five Legacy Rolls On
More than 70 years after the first 1955 Chevrolet appeared in showrooms, America’s fascination with the Tri-Five era shows no sign of fading.
The 2026 Tri-Five Nationals demonstrated why. These cars remain endlessly adaptable, equally at home as faithful restorations, traditional customs, hard-launching drag cars, cross-country cruisers, or cutting-edge pro-touring builds. Beneath all those different interpretations is a familiar shape—and a shared connection to one of Chevrolet’s most celebrated periods.
Our photographs offer only a sampling of what filled Beech Bend Raceway Park this year. Different models, different styles, and different approaches all came together for one unforgettable celebration of the ’55, ’56, and ’57 Chevrolet.
Welcome to the 2026 Tri-Five Nationals.
