Of the many American muscle cars to grace our earth throughout the decades, one manufacturer that seems to get far too little attention is that of Plymouth. Yes, it has a fanbase, but nowhere near the level of notoriety that Dodge or Ford still possess.
Still, that doesn't mean Plymouths are bad cars. In fact, we'd say that they consistently made sports cars that overachieved (relative to the rest). From the mid-'60s until the early-'80s, Plymouth muscle cars were a sight to behold!
Don't believe us? Well, to showcase how beautiful these works of art are, we compiled some of the coolest modified Plymouth's we could find – from the Belvedere to the 'Cuda.
10 1970 Plymouth Rapid Transit Caravan
To start off, we have a bit of a different kind of Plymouth. Rather than being a standard Rapid Transit', this is a customized Caravan alternative that's extremely rare!
Built by Roman Chariot Customs in Ohio, this Roadrunner Caravan is one of the few custom Rapid Transits ever made. As the name suggests, it's more of a truck/muscle car mix than the others - Similar to an El Camino, for instance.
9 Matt Balmer’s 1975 Plymouth Duster
To modify something effectively, you don't necessarily need to do a full upheaval of everything inside and outside of the vehicle. In fact, sometimes the best looking ones are those that are "tastefully" tuned. Case and point, Mr. Balmer's 1975 Plymouth Duster.
What started out as a base-level Duster quickly evolved into (what we believe to be) the cleanest Duster we've seen thus far! While equipped with a 408 cubic V8, new headers, upgraded carburetors, and much more, Balmer's Duster will easily dust anyone who'd challenge it!
8 LS-Swapped 1999 Plymouth Prowler
Speaking of clean-looking cars, we have another one: the Plymouth Prowler. No, this isn't your normal Prowler, but one with a power source that it's always needed: A Chevrolet Corvette's LS7!
From the outside, not much is different with this 1999 Prowler. However, it's what's under the hood that's got our attention. Using a Corvette-sourced LS7 crate engine, this Prowler goes from a strange-looking roadster into an open-top racecar.
Considering the power-to-weight ratio of a Plymouth Prowler and an LS7, we'd wager that this old thing can get to some crazy speeds!
7 1965 Plymouth A990 Belvedere Dragster
Next up, we have a quintessential 1960's-era car: the Plymouth Belvedere. Though, that doesn't mean it's exempt from a car enthusiasts desires, particularly those of going faster and faster. As such, you have examples like this one; a Plymouth Belvedere dragster.
As Hemmings describes when discussing the A990 Belvedere drag racer, it was "an unlikely first Super Stock World Champion." Yes, this once boring '60s family car metamorphized into a drag racing legend! All it took was a whole new engine, reworked chassis, and (well) everything else...
6 1970 Plymouth Superbird Restomod
With all the trends to come out of the modern automotive community, perhaps the coolest is that of 'restomods' - Restored and modified classic cars. As far as Plymouth's go, you can't get a better restomod than this 1970 Superbird, pictured here.
Along with a completely refurbished exterior this Superbird also has a current day HEMI V8 in the engine bay. Combining modern technology with classic styling is the sort of thing we've been missing for far too long, as evidenced by this beauty.
However, though this restored Superbird may be awesome, it's still nothing compared to the next entry's version...
5 Richard Petty’s 1970 Plymouth Superbird
Now, if we're going to be talking about excellent, modified Plymouth's, we'd have to be either foolish or insane to forget the O.G. example. None other than Richard Petty's 1970 Superbird; a classic NASCAR icon.
Even if you're not a fan of NASCAR, you've probably heard about/seen this car before (throughout various forms of media, such as Pixar's Cars). It's the ideal version of what oval-racing was back in the day; no strict regulations mandating a cars appearance or aerodynamics. If you could find your way around the rules, anything was possible.
4 1971 Plymouth Road Runner ‘Rapid Transit’
Similar to the previous Rapid Transit, the Caravan, this is the original version of what that one was mimicking: the 1971 Plymouth Roadrunner Rapid Transit - A custom made, one-of-a-kind muscle car!
Yes, you read that correctly. This Rapid Transit is a one-off modified version of the standard '71 Roadrunner. With an updated engine, suspension, and exterior appearance, this particular Roadrunner is a very costly one.
3 Fate of the Furious’ 1972 Plymouth Road Runner GTX
Finding, modifying, and restoring a classic muscle car is no easy task, especially if you're short on cash. Hollywood, however, is rarely short on funds, so they're able to commission all types of vehicles, including a 1972 Plymouth Roadrunner GTX - Featured in Fate of the Furious (2017).
This GTX was driven by Dom (Vin Diesel) towards the beginning of the film. Sadly, it didn't end up not getting much screen time overall. Still, we love it nonetheless!
2 1970 Plymouth Barracuda ‘Torc’
In the broader car community, there are a couple things that a majority of enthusiasts consider to be "taboo," so to speak. For instance: LS-swapping a Mazda RX-7, removing a Supra's 2JZ, or even diesel-swapping a beloved muscle car.
Even still, that didn't stop one owner from doing the last choice; taking a 1970 Plymouth Barracuda and dropping in a diesel engine. It's crazy, we know. Though, it's not without purpose...
Because of its 6.7-liter Cummins diesel engine and twin-turbos, this 'Cuda will pump out over 1,500-hp and a ludicrous 3,000+ ft-lb of torque. Now you know why it's called "Torc."
1 1970 Plymouth Barracuda ‘Street Machine’
Last, but certainly not least, is one of our personal favorite antique Plymouth's. Of course, we're talking about the one seen here - the 1970 Plymouth Barracuda 'Street Machine'.
Like the aforementioned Superbird restomod, this 'Street Machine' has a brand new HEMI V8 swapped into it. We could give all the specs on this thing, but that's not what really impresses us. No, that would be its appearance. The pearl white paint with the black stripes/accents is just too perfect for this beast. If this is what love feels like, we're head over heels!
