1000HP 1968 Plymouth Road Runner “Old Runner”

When Dennis Ermi bought this 1968 Plymouth Road Runner in 2009, it needed serious paint and engine work before it earned the nickname “Old Runner.” Today it runs a supercharged 472 cubic-inch engine producing roughly 1,000 horsepower under a pearlescent orange-and-black finish. One commenter recognized himself standing next to it in the video and left a promise instead of a caption: “till death do us part.”

Not every car at a show has a nickname, and fewer still have one that fits as well as this one does. Dennis Ermi didn’t buy a finished showpiece back in 2009 — he bought a project, something that needed real work before it earned the right to be called what it’s called today. Under the hood sits a 472 cubic-inch engine putting out somewhere around 1,000 horsepower, wrapped in a pearlescent orange-and-black paint job that makes it impossible to miss on a crowded show floor. One commenter, watching the video, recognized himself standing next to his own Road Runner and left a comment that reads more like a vow than a caption. What was this car before Ermi got hold of it, and how far did it have to come?

A 1968 Road Runner Named “Old Runner”

This 1968 Plymouth Road Runner was filmed by Lou Costabile for his “My Car Story” series on February 23, 2017, at the World of Wheels show at Wisconsin State Fair Park in West Allis. Its owner, Dennis Ermi, has had the car since 2009, and the nickname “Old Runner” has stuck to it well enough that it’s now how the car gets referred to at shows rather than by year and model alone. That kind of informal branding tends to happen with cars that develop a real personality over years of ownership, appearing at the same regional shows repeatedly until regulars start recognizing them by nickname before they even check the badge. Costabile’s series has built a reputation for finding exactly these kinds of cars — not pristine trailer queens with no story, but builds with an owner standing next to them who can explain every decision that went into getting the car to where it is now.

From Project Car to Showpiece

When Ermi bought the car in 2009, it wasn’t in anything close to the condition it’s in today — the Road Runner needed significant paint and engine work before it became the car now drawing crowds at World of Wheels. That transformation from a rough project into a fully sorted, show-ready muscle car represents years of investment, both financial and mechanical, the kind of long build that rarely gets fully appreciated by someone seeing the finished result for the first time. Road Runners from this era were originally marketed as budget-friendly muscle cars, which means many surviving examples spent decades as daily drivers or amateur project cars before receiving serious restoration attention, often changing hands multiple times along the way. Ermi’s approach — buying a car that needed work and staying with it long enough to finish the job himself rather than flipping it mid-build — is part of why “Old Runner” carries the kind of personal ownership story that resonates with viewers of the video.

The 1968 Road Runner’s Place in Plymouth History

Plymouth introduced the Road Runner for the 1968 model year as a deliberately stripped-down, affordable muscle car, aimed at buyers who wanted serious straight-line performance without paying for the trim and comfort features loaded onto pricier competitors. The formula worked immediately — the Road Runner became one of the best-selling muscle cars of its debut year, helped by a horn that literally beeped like the Warner Bros. cartoon character whose name and likeness Plymouth licensed for the car. That combination of genuine performance and a stripped-price approach set the Road Runner apart from more upscale muscle cars of 1968 like the GTO or the 442, positioning it as the car for buyers who cared more about what was under the hood than what was on the dash. A 1968 example like this one, built during the model’s very first year, carries the historical weight of launching one of the most recognizable nameplates of the entire muscle car era.

The 472 and Roughly 1,000 Horsepower

The engine bay tells a very different story than what left the factory in 1968 — this Road Runner now runs a 472 cubic-inch powerplant producing an estimated 1,000 horsepower, a figure that puts it well outside anything Plymouth offered even in the Road Runner’s most aggressive factory configurations, including the 426 Hemi option. Getting to four figures of horsepower on a big-block platform like this typically requires forced induction, and the supercharger whine commenters specifically praise in the video is consistent with that kind of build approach, delivering both the power figure and the distinct mechanical soundtrack that draws attention on a show floor. That level of output transforms the car from a period-correct muscle car into something closer to a modern pro-street build wearing a vintage body, a common path for owners who want the aggressive looks of a classic Road Runner combined with performance numbers no factory big-block ever approached.

Pearlescent Orange and Black: A Paint Job Built to Be Seen

The car’s pearlescent orange-and-black paint scheme is part of what makes “Old Runner” instantly recognizable at shows, a modern pearl finish that catches light differently than any factory paint option Plymouth offered in 1968. That kind of paint choice reflects the restoration’s overall philosophy — rather than chasing strict factory-correct authenticity, the build leans into a bold, show-oriented finish designed to stand out among dozens of other muscle cars on a crowded floor. Paired with the aggressive supercharged engine note, the paint scheme reinforces the car’s identity as a driver-focused build rather than a numbers-matching restoration aimed at concours judging. Commenters repeatedly describe the finished car as an “honest, old fashioned muscle car” despite the modern power upgrades, suggesting the paint and overall presentation still reads as true to the Road Runner’s original stripped-down, performance-first character even with a thoroughly modern drivetrain underneath it.

The Owner Behind the Build

One of the more memorable exchanges in the video’s comment section comes from a viewer who identifies himself as the man featured standing next to his own Road Runner, closing his comment with “till death do us part” — a line that captures exactly the kind of long-term attachment cars like this tend to generate in their owners. That sentiment lines up closely with Ermi’s own history with “Old Runner,” a car he’s owned since 2009 and personally guided through the transformation from rough project to finished show car. Long-term single-owner builds like this tend to carry a different weight at shows than recently acquired or flipped cars, since the person answering questions about the build actually made every decision along the way rather than inheriting someone else’s finished work. It’s part of why Costabile’s interview format works so well for cars like this — the story only really lands when the owner telling it is the same person who lived through the whole build.

Comparable Muscle Cars from the Road Runner’s Era

Positioned against its 1968 contemporaries, the Road Runner competed directly with cars like the Pontiac GTO, the Chevrolet Chevelle SS, and Plymouth’s own upscale GTX, all chasing the same buyer looking for maximum performance per dollar. What set the Road Runner apart within that field was its deliberately bare-bones approach — Plymouth stripped out comfort and convenience features to keep the base price low, banking on buyers who wanted the fastest car for their money rather than the most refined one. A heavily modified example like “Old Runner,” now running a supercharged 472 producing roughly 1,000 horsepower, has effectively leapfrogged every factory-original rival from that era in outright output, illustrating just how far the aftermarket has pushed platforms that started life as budget muscle cars. That gap between factory-original rivals and modern-built examples like this one is part of what makes shows like World of Wheels interesting: period-correct cars and heavily built modern interpretations often sit within a few feet of each other.

Restoration Considerations for a 1968 Road Runner Build

Builds like “Old Runner” highlight the choices facing anyone restoring a first-year Road Runner today: chase factory-correct paint codes and original 383 or 426 Hemi engine options for maximum authenticity value, or follow Ermi’s path and build toward maximum performance and show presence with a big-block swap and forced induction. Sourcing period-correct sheet metal for 1968 Road Runners has grown more difficult as more surviving examples get parted out or heavily modified, making low-mileage, rust-free donor cars increasingly valuable even for builds that plan to deviate significantly from original specification. Engine work at the level seen here — a 472 cubic inch supercharged setup capable of roughly 1,000 horsepower — requires substantial supporting modifications to the drivetrain, cooling, and chassis to handle the additional stress, work that typically extends a build timeline by years rather than months. Ermi’s ownership since 2009 suggests exactly that kind of extended, deliberate build process rather than a quick weekend modification.

Why “Old Runner” Still Resonates with Muscle Car Fans

What keeps a car like “Old Runner” resonating with viewers years after this video was filmed is the combination of an honest, blue-collar nameplate history with a build that pushes far past what the factory ever offered, without losing the car’s fundamental character. Commenters from as far away as Australia leave greetings under the video, a reminder of how far a well-told car story travels once it’s online, reaching an audience well beyond the regional car show circuit where it was actually filmed. The repeated description of the car as an “honest, old fashioned muscle car,” even with a supercharged four-figure-horsepower engine under the hood, speaks to how successfully the build balances raw modern performance with the visual and cultural identity that made the original 1968 Road Runner popular in the first place. For fans of the model, “Old Runner” stands as proof that a budget muscle car nameplate can still headline a build this ambitious more than five decades later.
