Viper-Powered 1970 Plymouth Barracuda Heads to Mecum

The world of classic muscle cars meets modern performance in the form of this jaw-dropping 1970 Plymouth Barracuda, set to cross the auction block at Mecum Houston 2025 on Saturday, May 17. Dubbed “Six Shooter,” this custom-built convertible is more than just a ’Cuda with a Viper engine—it’s essentially a Dodge Viper disguised as a vintage Mopar.

The Power of a Viper in a Classic ’Cuda – 

Under the hood sits a Gen2 8.0-liter (488 cubic-inch) VIPER V-10, producing 450 horsepower, paired with a Borg Warner T56 6-speed manual transmission. The powertrain and drivetrain were sourced from a 1998 Dodge Viper ACR, giving this classic an exotic sports car’s handling and brute force. A custom exhaust system with 3-inch Spin Tech mufflers adds an aggressive growl to match its beastly performance.

A Show-Stopping Custom Build – 

This isn’t just a resto-mod—it’s a complete transformation. Nearly every part of this Six Shooter has been modified or reworked. The custom suspension and gas shocks ensure a smooth yet responsive ride, while the Colorado Custom wheels wrapped in Michelin tires provide grip to handle all that power. Shaved door handles, deleted marker lights, a custom front spoiler, and body-colored mirrors give it a sleek, refined look, while the electric motor-operated hood and trunk add modern convenience.

High-Tech Interior with Viper Influence – 

Inside, this 1970 Barracuda is packed with modern upgrades. The dashboard and seats come straight from a Gen2 Dodge Viper, maintaining the donor car’s sports car feel. The custom stereo system, power-operated convertible top, power windows, and remote-controlled hood and trunk bring luxury and technology together in a way rarely seen in classic muscle cars.

From SEMA Star to Auction Headliner – 

The Six Shooter made its first public appearance at the SEMA Show in 2003, where it gained recognition as one of the most technically advanced muscle cars ever built. Mopar Action Magazine declared, “The Six Shooter ‘Cuda has moved the bar high enough that it’s not about to be hurdled, let alone raised, any time soon.”, while Hot Rod Magazine called it part of the “Next Big Thing” in custom muscle car building.

A Rare Opportunity for Collectors – 

This Viper-powered 1970 Plymouth Barracuda Six Shooter is more than just a car—it’s a piece of automotive history. As serial number #0001 of what was intended to be a limited-production series, this one-of-a-kind convertible represents the perfect fusion of old-school Mopar muscle and modern Dodge Viper performance. With its rare build, SEMA pedigree, and head-turning design, it’s sure to be one of the most anticipated vehicles at Mecum Houston 2025.
