Pro-Touring 1973 Plymouth Barracuda Packs 700-Plus Horsepower With Modern Mopar Performance UpgradesA heavily modified 1973 Plymouth Barracuda is bringing modern pro-touring engineering to one of Mopar’s most iconic muscle car platforms, blending classic E-body styling with more than 700 horsepower and a long list of contemporary suspension and drivability upgrades.Check out these cars for sale:1983 Buick Electra Park Avenue1951 Pontiac Chieftain Custom Street RodPierce Arrow MotoretteCadillac DevilleAdvertisementAdvertisementFinished in bright red over a black interior, the coupe has been transformed with a full 1971 ’Cuda conversion, giving the later-model Barracuda the more aggressive appearance associated with the peak years of Chrysler’s muscle car era. The conversion helps capture the unmistakable look that made the early 1970s E-body cars some of the most recognizable performance machines of their time.Power comes from a built 440 cubic inch Mopar V8 that has been stroked to 493 cubic inches. The engine reportedly produces more than 700 horsepower thanks to a combination of forged internal components, a Comp solid roller camshaft, Mopar Performance aluminum cylinder heads, and modern electronic fuel injection technology.Rather than relying on traditional carburetion, the engine uses an Edelbrock Victor multiport EFI intake paired with a Fast XFI fuel injection system, giving the large-displacement big block more precise fuel delivery and improved tuning capability. Supporting modifications include MSD ignition components, Hooker Super Comp headers, and a March serpentine accessory system.Backing the engine is a built 727 automatic transmission connected to an 8¾ rear axle equipped with 3.55 gears, a posi differential, and Mark Williams axles. An aluminum driveshaft and subframe connectors were also added to improve durability and help transfer the substantial power output to the pavement more effectively.AdvertisementAdvertisementWhile the car retains the intimidating straight-line personality expected from a high-horsepower Mopar, the build extends well beyond drag racing performance. The suspension system was upgraded with an RMS AlterKation front suspension setup, StreetLynx rear four-link system, Viking coilovers, and power rack-and-pinion steering to deliver sharper handling and improved road manners.Braking performance was also modernized with hydroboost-assisted power brakes and Wilwood front disc brakes, while an aluminum radiator with an electric cooling fan helps manage engine temperatures during aggressive driving.Inside, the black bucket-seat interior maintains a driver-focused layout with a floor-mounted shifter, center console, and Speedhut gauges providing key performance data. An aftermarket stereo system adds a measure of comfort for cruising, though the cabin largely keeps the focus on performance and functionality.Exterior details continue the aggressive theme with an AAR-style hood secured by hood pins, rally wheels, and a lowered performance stance that complements the car’s modern suspension upgrades.AdvertisementAdvertisementThe early 1970s marked a changing period for American muscle cars as emissions regulations and insurance costs began reshaping the market. Builds like this modified Barracuda reflect continued enthusiasm for the era’s high-performance Mopar platforms while incorporating modern engineering solutions that improve reliability, handling, and drivability.Showing 2,689 miles, the customized Barracuda is listed for $92,999 and represents a modern interpretation of classic Mopar muscle with contemporary pro-touring capability.⚡️ Read the full article on MotoriousSign up for the Motorious Newsletter.
