1970 Plymouth ‘Cuda AAR: Muscle Car Of The Week

V8TV’s “Muscle Car of the Week” spotlights a Rally Red 1970 Plymouth ‘Cuda AAR — the numbers-matching, 340 Six-Barrel-powered homologation special built for exactly one model year. Housed today in The Brothers Collection, this AAR carries the tighter steering ratio and unmistakable strobe stripe that set it apart from every other ‘Cuda on the road. Watch to see why collectors call it the sharpest example they’ve found.

There’s a moment in every ‘Cuda AAR conversation where someone says the phrase “mic drop,” and it’s usually right after this exact car comes up on screen. Rally Red paint, a strobe stripe that still looks aggressive parked in a showroom, and a numbers-matching drivetrain that most restorers only dream of documenting this completely — this is the car V8TV built an entire episode around, and it’s easy to see why once you know what’s actually hiding under that fiberglass hood scoop.

The 340 Six-Barrel’s Secret Advantage

Under the hood sits Chrysler’s 340-cubic-inch small block fitted with the Six-Barrel setup, three two-barrel Holley carburetors mounted on an aluminum intake instead of the single four-barrel most 340-equipped Barracudas carried from the factory. The 340 weighed noticeably less than the 440 big block offered elsewhere in the Barracuda lineup that same year, and that weight difference over the front wheels made a real, measurable handling difference on a car that was built from the ground up with racing in mind rather than straight-line bragging rights alone.

AAR’s Tighter Steering Ratio

One detail longtime AAR owners bring up before almost anything else on the car: the steering ratio. AAR ‘Cudas got a noticeably tighter steering ratio than standard Barracudas straight from the factory, a change tied directly to the car’s racing origins rather than any showroom marketing decision. AAR stands for All American Racers, Dan Gurney’s team, and Plymouth built this exact trim specifically to satisfy Trans-Am homologation requirements, meaning the car had to legally exist on dealer lots before the racing version could even compete on a track.

Reading the Strobe Stripe

The side strobe stripe running the length of this car isn’t a generic 1970s decal package pulled from a parts catalog. It’s a specific AAR design element, visually distinct from the standard ‘Cuda’s stripe treatments that year, and it’s one of the fastest ways for a knowledgeable enthusiast to spot a genuine AAR from clear across a parking lot, well before anyone gets close enough to check the fender badges or VIN tag.

What ‘Numbers-Matching’ Really Means Here

“Numbers-matching” gets thrown around loosely in the classic car world, tossed into nearly every listing regardless of how much verification actually backs it up, but on this car it means something specific and independently verified: the engine, transmission, and rear end all carry the stamped codes that trace back directly to this car’s original build sheet. For a low-production trim like the AAR, that kind of complete, cross-checked documentation is unusual enough on its own to be the headline feature of the entire car.

Inside The Brothers Collection

This particular ‘Cuda lives today in The Brothers Collection, described directly in the video as home to one of the sharpest AAR examples the show’s producers have found in years of filming similar features. Private collections like this one rarely put their cars in front of cameras at all, which makes an appearance like this one genuinely worth paying attention to for AAR-specific details that simply don’t surface very often in more casual car-show coverage.

1970: The Only Year AAR Existed

The AAR ‘Cuda only existed for the 1970 model year, full stop. Plymouth built it to satisfy a one-time racing homologation requirement, and once that requirement had been met on paper, the trim disappeared from the lineup entirely the following year. That narrow, single-year production window is exactly why surviving, well-documented examples like this one carry outsized value among serious Mopar collectors today compared to other Barracuda trims produced across multiple years.

Why Enthusiasts Call the 340 the Real Muscle Motor

Big block ‘Cudas get most of the casual attention in general muscle car conversation, but small block loyalists consistently point to the 340 as the more honest muscle car engine: quicker revving, better balanced front to rear, and in Six-Barrel form still capable of embarrassing bigger, heavier competition off the line despite giving up raw cubic inches. It’s a debate this exact car settles firmly in the AAR’s favor for a lot of viewers who watch the episode start to finish.

A Car That Still Draws a Crowd

A viewer in the comments put it plainly and without much qualification: this car looks better than anything currently on the road today, even parked in bare gray primer with no paint at all. That’s the kind of praise a fifty-plus-year-old design rarely earns from a modern audience raised on far more advanced automotive engineering, and it’s a large part of why the AAR ‘Cuda has only grown more desirable, and more expensive, as the decades have passed.

1970’s Wild Trans-Am Season

The AAR ‘Cuda’s existence only really makes sense against the backdrop of the 1970 Trans-Am season, one of the most competitive years the series ever ran. Plymouth, Ford, Chevrolet, and American Motors all fielded serious factory-backed efforts that year, and the street cars each brand had to sell to qualify, the AAR ‘Cuda, the Boss 302 Mustang, the Z/28 Camaro, and the Trans Am-spec Javelin, have all become some of the most collected muscle cars from the entire era specifically because of that one wild season of racing.

The Numbers Matching Premium in the Mopar Market

Among Mopar collectors specifically, the gap between a claimed numbers-matching car and an independently verified one has only widened as prices have climbed. Buyers who got burned by loosely documented cars in years past now expect build sheets, broadcast sheets, and matching casting dates before they’ll pay top dollar, and a car housed inside a known private collection like The Brothers Collection carries an added layer of credibility simply because of who has already vetted it before it ever reached a camera crew.

Spotting a Fake AAR from the Real Thing

Because genuine AAR ‘Cudas command such a premium over standard Barracudas, the model has attracted its share of clones and outright fakes over the decades, cars dressed up with AAR stripes and badging but lacking the actual factory hardware underneath. That’s exactly why documentation like this car carries matters so much to serious buyers: matching fender tags, broadcast sheets, and casting numbers are what separate a real AAR from a very convincing tribute car wearing the same stripes.
