2 Trans-Am Icons Found Stashed in the Same Barn: 1969 Chevrolet Camaro Z/28 & 1970 Plymouth AAR ’Cuda

Matt Barczak was driving to inspect a rare Hemi Road Runner when his father read a strange trim code off a classified ad from the back seat: what’s an X33 Camaro? That single question sent Matt three and a half hours across Pennsylvania in the middle of a January night — and what waited in the barn wasn’t just one forgotten Trans-Am homologation car. Read on to find out what a documented 1969 Z/28 and a 1970 AAR ‘Cuda were doing under the same dusty roof.

“You find a good car, you cannot sit,” Matt Barczak says, and he’s not exaggerating — the discovery that follows happened because his own father couldn’t stop reading a local trader paper out loud in the back seat of a truck. Matt was 35, professionally restoring and collecting muscle cars alongside Frank Arone of Arone Restorations in Homer City, Pennsylvania, when a routine drive to look at one barn find turned into something nobody in that truck expected. What they found waiting in that barn wasn’t one forgotten Trans-Am homologation car. It was two.

When a Trim Tag Code Changes Everything

The trip started as a mission to inspect a 7,000-mile, original-paint 1969 Hemi Road Runner. Matt’s father, killing time in the back seat with the local trader paper, read off a line that nearly put the truck in a ditch: “Hey Matt, what’s an X33 Camaro?” On a 1969 Camaro trim tag, X33 is the factory code for the Z/28 option — the code Chevrolet stamped on exactly 20,302 cars built that year to satisfy SCCA Trans-Am homologation rules, wearing the small-block DZ 302 that Chevrolet engineers built specifically to skirt the series’ 5.0-liter displacement cap by pairing a 4.00-inch bore with a 3.00-inch stroke.

A Phone Call That Couldn’t Wait Until Morning

Matt called the seller that same night and told him flatly: “I am 3 1/2 hours away. I can be at your house by 10 o’clock.” It was January 2016, roughly six in the evening, the kind of timing that would make most buyers wait until daylight. Matt didn’t wait, because he understood exactly what a genuine, documented X33 trim tag meant, and he knew every hour of delay was an hour some other buyer could beat him to it.

Two Trans-Am Legends, One Dusty Barn

What waited in that Pennsylvania barn wasn’t just the Z/28. Parked beside it was a 1970 Plymouth AAR ‘Cuda, Plymouth’s own one-year-only Trans-Am homologation special, built to satisfy the SCCA’s 2,500-unit minimum with a run of just 2,724 cars completed in a five-week window between March and April of 1970. The AAR ran a 340 Six Pack — three Holley two-barrels feeding a 340-cube small-block rated at 290 factory horsepower — wearing a functional fiberglass hood scoop and the model’s signature side-exit exhaust, features no other Barracuda variant carried.

Why Homologation Specials Command Such Respect

Both cars exist purely because racing sanctioning bodies forced manufacturers to build and sell a minimum number of road-going versions of their competition machinery — a rule that turned the Z/28 and the AAR ‘Cuda into genuinely rare factory products rather than mass-market performance trims. That homologation requirement is exactly why both nameplates carry a cachet among collectors that ordinary high-performance variants simply don’t match.

The DZ 302’s Clever Engineering Solution

Chevrolet’s engineers didn’t stumble into the Z/28’s unusual 302 cubic inch displacement by accident — it was a deliberate answer to a rulebook. SCCA Trans-Am racing capped engine displacement at 5.0 liters, or roughly 305 cubic inches, and Chevrolet’s team calculated the exact bore and stroke combination needed to build the largest legal engine under that ceiling. That same engineering discipline carried over into the street version, giving buyers a small-block tuned to rev hard rather than simply make peak torque low in the range.

What It Takes to Verify a Genuine Example

Finding a car like this in a barn is only the first step — verifying it required cross-referencing the trim tag code against Chevrolet’s original documentation, confirming the VIN sequence matched genuine Z/28 production, and checking for the drivetrain components specific to the homologation package rather than a later add-on. That verification process is exactly what separates a documented barn find from an expensive guess, and it’s work restorers like Frank Arone specialize in.

Two Homologation Specials, One Impossible Coincidence

Finding either of these cars stashed away and forgotten would be a story. Finding both under the same roof, discovered because of six characters on a trim tag, is the kind of barn find every restorer dreams about and almost none of them get. The odds of two separate manufacturers’ homologation specials ending up in the same barn, let alone being discovered on the same visit, are close enough to zero that most collectors go a lifetime without ever hearing a comparable story.

What Happens to a Find Like This Next

Cars discovered in this condition typically face years of careful restoration work before they’re roadworthy again, a process that Arone Restorations has built its reputation around handling correctly rather than quickly. For homologation specials specifically, that means sourcing period-correct parts, verifying every component against factory documentation, and resisting the temptation to improve anything that would compromise the car’s numbers-matching status.

Why This Story Still Resonates With Collectors

Stories like Matt Barczak’s are exactly why so many collectors keep chasing barn finds decades after the supply of genuinely undiscovered cars has dwindled to almost nothing. It’s proof that patience, knowledge of obscure trim codes, and a willingness to drive three and a half hours in the middle of a January night can still occasionally turn up something extraordinary — even in an era when most people assume every barn in America has already been searched.

A Reminder That Trader Papers Still Matter

In an era when most serious car hunting happens through online listings and specialized forums, this story is a reminder that local classified papers can still hide genuine discoveries that algorithm-driven searches would never surface. Matt’s father wasn’t even looking for a car when he spotted the ad — he was simply passing time on a long drive, which is exactly the kind of accidental discovery that keeps barn-find stories circulating in the hobby.

Why Pennsylvania Kept Both Cars Hidden So Long

Rural Pennsylvania has a long-documented history of holding onto forgotten performance cars precisely because its farming and small-town communities tend to keep vehicles rather than scrap them, storing project cars in barns for decades rather than selling them off. That regional pattern is part of why serious restorers like Frank Arone specifically watch classified listings and estate sales in exactly this kind of area, since Pennsylvania barns have produced a disproportionate number of genuine homologation-special discoveries over the years.
