Plymouth built the 1971 ‘Cuda with a look it never repeated: quad headlights, fender gills, and billboard graphics found on no other year. UFC president Dana White picked exactly this rare-bodied ‘Cuda for a full restomod, swapping in a 425-horsepower 440 and a Curry 9-inch rear end. The result became one of MuscleCar’s most-watched builds ever.
Plymouth only built the Barracuda with four headlights for a single model year, and most people who see one today have no idea why it looks different from every ‘Cuda around it. The fender-mounted “gill” louvers are a one-year-only detail too, gone before 1972 rolled around. So when UFC president Dana White wanted a build that would turn heads at any show, MuscleCar’s crew at PowerBlock reached for exactly this car: a tired, slant-six 1971 Plymouth ‘Cuda with none of its original muscle left. What came out the other side was a 425-horsepower restomod wearing Chip Foose-designed wheels and a name that stuck instantly — the “UFC Street Fighter.” It remains one of the most-watched full builds the show has ever put out, and it says as much about why the 1971 ‘Cuda still matters as any factory Hemi car does.
The Build That Made Dana White’s ‘Cuda Famous
The donor car wasn’t a numbers-matching legend. It was a straight-six ‘Cuda with none of the drivetrain the model is known for — which is exactly the kind of car that lets a build team start from zero. MuscleCar’s crew tore it down to a bare shell, added subframe connectors and a custom K-member, and built the chassis around a full Curry 9-inch rear end with significantly upgraded rear suspension. None of that shows up in a walk-around video, but it’s the difference between a car that looks fast and one that actually handles like a modern muscle car.
Under the shaker hood sits a freshly built 440 making 425 horsepower, backed by a top-of-the-line GearStar 727 TorqueFlite transmission. The car left the shop wearing custom Mopar wheels designed by Chip Foose and fresh graphics that, according to viewers who watched the build unfold, went through at least one revision — early cutout logos referencing the UFC brand were replaced with simpler “440” badging by the time the car was finished. The project originally aired as an episode of MuscleCar on PowerNation, and it’s since become one of the network’s most-replayed full-build recaps, racking up over two million views on YouTube alone. Long-time viewers still describe waking up on Saturday mornings specifically to catch builds like this one when the show first aired, which says something about how much staying power a well-documented restomod can have decades after the fact.

MuscleCar built its reputation on exactly this kind of transformation — taking a rough, non-numbers-matching classic and showing every stage of turning it into something that can be driven hard, rather than restoring a car back to a stock configuration nobody plans to actually use.
Why the 1971 ‘Cuda Is the Rarest Year to Build On
Plymouth’s E-body Barracuda ran from 1970 through 1974, but 1971 stands apart from every other year in the run. It’s the only year the ‘Cuda wore quad headlights instead of the single round lights used in 1970 and again from 1972 on. It’s also the only year with those bright fender louvers ahead of the front wheels, and the only year Plymouth offered the bold “billboard” graphics package that wrapped the rear quarter panels in oversized lettering. Collectors treat 1971 as its own distinct sub-generation of the ‘Cuda for exactly these reasons — the styling cues simply don’t exist on any other model year, which is part of why a build like this one stands out even among other Mopar restomods.
1971 also closed out an era under the hood. Tightening federal emissions regulations forced Chrysler to drop engines larger than 383 cubic inches from the ‘Cuda lineup after that year, which makes 1971 the last model year a buyer could order a factory 440 or 426 Hemi in a Barracuda at all. The factory 440-6 Six Pack option that year was rated at 385 advertised horsepower, though enthusiasts and period road tests have long argued the real number under load was higher. Only 254 ‘Cudas left the factory with that 440-6 package in 1971, with the convertible version limited to just five cars — numbers that explain why original 440-6 ‘Cudas now change hands for hundreds of thousands of dollars whenever one surfaces at auction.
The Barracuda shared its E-body platform with the Dodge Challenger, and the two are often lumped together as basically the same car wearing different sheet metal. The quad-headlight 1971 front end is one of the clearest ways to tell them apart at a glance, since the Challenger kept four headlights across its entire run while the ‘Cuda only wore them this one year. For anyone shopping a Mopar restomod project specifically for its styling, that single detail is often the deciding factor between the two.
What Makes This Build Different From a Factory Restoration
A numbers-matching 440-6 ‘Cuda is a museum piece — you don’t drive it hard and you definitely don’t modify it. That’s exactly why builders looking for a driver-quality Mopar gravitate toward the slant-six and small-block cars that Plymouth built by the thousands. They carry the same one-year-only sheet metal and the same instantly recognizable silhouette, without the six-figure price tag attached to an original big-block car. Dana White’s ‘Cuda is the clearest possible example of that formula working: modern rear suspension geometry, a built 440 that outmakes the factory Six Pack rating, and a transmission designed for street abuse instead of a stock TorqueFlite that was never meant to handle 425 horsepower reliably.
The visual details matter just as much as the mechanical ones. Foose’s wheel design was built specifically to sit inside 1971’s factory wheel arches without looking like a modern car wearing a costume, and the shaker hood scoop — functional on the original Six Pack cars — was kept as both a nod to the car’s roots and a way to feed the new engine. It’s a build that respects why the 1971 ‘Cuda looks the way it does while updating everything that makes a 50-year-old car difficult to live with day to day, and it’s a template a lot of Mopar builders have leaned on since: keep the one-year-only body, replace everything a driver actually feels.
