Key Takeaway

• A 1969 Plymouth GTX has been transformed into a supercharged, Viper V10-powered restomod, showcasing modern performance upgrades while maintaining its classic Mopar roots.

In the realm of classic Mopar muscle cars, enthusiasts have always found ways to breathe new life into their cherished vehicles. Among these projects, a standout example is the supercharged, Viper V10-powered Plymouth GTX. Originally equipped with a 440 cu-in, 7.2-liter V8, this vintage beast has undergone a dramatic transformation, upping its piston count to ten and adding modern performance upgrades. This build, completed in 2010, is a testament to the enduring appeal of classic muscle cars and the ingenuity of their owners.

The Classic Mopar Transformation

Mopar fans have a long history of swapping modern Hemi and Hellcat V8 engines into classic muscle cars. These eight-cylinder powerhouses have become a staple in the restomod community, but for one previous owner of this vintage Plymouth GTX, eight cylinders simply weren’t enough. Determined to create something truly unique, they opted to install an SRT-10 Viper V10 engine, maintaining the car’s Chrysler roots while significantly boosting its performance.

The decision to incorporate the SRT-10 Viper V10 engine was just the beginning. The owner also added a supercharger, creating a monstrous combination that transformed the GTX into a high-powered machine. This wild build, completed over a decade ago, showcases the dedication and creativity that define the muscle car community.

Performance Upgrades And Power Output

The auction listing on Bring a Trailer doesn’t specify the exact power output of this supercharged Viper V10-powered Plymouth GTX. However, it’s worth noting that a stock, third-generation ZB I Viper roadster was rated at 500 hp (507 PS) and 525 lb-ft (712 Nm) when new. Given the addition of the Paxton supercharger, methanol injection, and other performance upgrades, it’s safe to assume that this GTX’s power output has been pushed deep into the 700-horsepower category.

Whatever the exact numbers, there’s no doubt that this GTX is significantly faster and more powerful than it was when it left the factory in 1969. Back then, it was already an impressive performer, but the enhancements made during this build have taken it to a whole new level.

The Original 1969 Plymouth GTX

To appreciate the extent of this transformation, it’s important to understand the capabilities of the original 1969 Plymouth GTX. A more upmarket take on Plymouth’s Road Runner, the GTX skipped the Runner’s base 335 hp (340 PS) 383 cu-in (6.3-liter) V8 and went straight to the 375 hp (380 PS) 440 (7.2-liter) engine. This powerplant could deliver 0 to 60 mph times in 6.8 seconds, making the GTX a formidable competitor on the streets.

The GTX also offered the legendary 426 (7.0-liter) Hemi as a 425 hp (430 PS) option. Mid-year, Plymouth added the triple-carb Six Pack 440, which produced 390 hp (396 PS). Even allowing for the different way ‘gross’ power was calculated back then, these engines provided plenty of power and performance.

Modern Enhancements And Upgrades

While the original GTX was no slouch, the modern enhancements and upgrades made to this particular model set it apart from its peers. The SRT-10 Viper V10 engine swap is a bold move that significantly increases the car’s performance capabilities. Coupled with the Paxton supercharger, methanol injection, and other performance modifications, this GTX is now a true powerhouse.

One of the standout features of this build is the inclusion of a six-speed manual transmission. This transmission, sourced from the same Viper that donated the engine and bucket seats, provides a level of control and engagement that wasn’t available with the original setup. Additionally, the car is equipped with Wilwood cross-drilled discs, six-piston calipers, and sticky Michelin radials.

These modern performance parts ensure that the GTX can handle the increased power and provide a thrilling driving experience. The 18-inch wheels, which resemble up-sized versions of the original 15-inch Magnum 500 rims, complete the look. These wheels not only enhance the car’s appearance but also accommodate the larger brakes and provide improved handling.

A Unique Sound And Driving Experience

One of the most intriguing aspects of this build is the sound produced by the Viper V10 engine. While Dodge’s V10 has a reputation for sounding somewhat underwhelming, the combination of the V10 and the supercharger in this GTX creates a unique auditory experience. The seller has promised to add videos to the auction listing, which will undoubtedly showcase the car’s distinctive sound.

Driving this GTX is sure to be an exhilarating experience. The power and performance enhancements, coupled with the modern transmission and braking system, make this car a true standout in the world of muscle car restomods. Despite the build being completed years ago, the car still looks and performs great, a testament to the quality of the work done.

Our Conclusion

The supercharged, Viper V10-powered Plymouth GTX is a remarkable example of what can be achieved when classic muscle cars are given modern performance upgrades. This build, with its SRT-10 Viper V10 engine, Paxton supercharger, and other enhancements, transforms the GTX into a high-powered, unique vehicle that stands out even among other restomods.

For Mopar enthusiasts and muscle car fans alike, this GTX represents the pinnacle of creativity and performance.
