A 174-Day GM Strike Nearly Killed the Firebird in 1972 — This Formula 400 Is One of the Survivors

Only about 5,250 Firebird Formula 400s were built for 1972, after a 174-day Norwood plant strike cut Pontiac’s production nearly in half and had GM executives weighing whether to kill the model outright. One desert-kept survivor shows what almost never left the factory.

In the spring of 1972, the United Auto Workers walked off the job at General Motors’ Norwood, Ohio assembly plant, and they didn’t come back for 174 days — the longest strike in company history at the time. By the time it ended that September, Firebird production for the year had collapsed from more than 53,000 units to under 30,000, GM executives were seriously debating whether to kill the Firebird and Camaro lines outright, and roughly 1,100 partially built cars never made it off the line at all. One of the survivors that somehow got through is the pale green 1972 Pontiac Firebird Formula 400 featured in this episode of Cars, Shops & Collections — a car its current owner, known on the show as Pontiac Ed, bought on a whim the moment he saw the listing photos.

The Strike That Almost Ended the Firebird

The 174-day walkout at Norwood wasn’t just an inconvenience — it reshaped the entire 1972 Firebird model year. Industry figures put total Firebird production at 53,124 for 1971, and only 29,951 for 1972, a drop of better than 43 percent. The damage went beyond lost volume. Roughly 1,100 cars that were partway through assembly when the line stopped were ultimately scrapped rather than finished, because by the time workers returned it was no longer economically practical to bring those unfinished shells up to the tightening 1973 federal safety and emissions standards. GM leadership reportedly weighed scrapping the Firebird and Camaro platform entirely rather than absorb the losses — a decision that, had it gone the other way, would have ended both nameplates nearly a decade before their actual retirements in the early 1970s wind-down of the muscle car era.

Against that backdrop, a 1972 Formula 400 that actually made it into a customer’s driveway is a small miracle of timing. Industry estimates put total Formula production for the year at only around 5,250 cars, a sliver compared to the roughly 12,000 base coupes and 11,415 Esprits built that same model year. The Formula split the difference between Pontiac’s bare-bones Firebird and the flashier, spoiler-laden Trans Am — most of the performance, none of the show-car styling — and 1972’s chaos made it rarer than Pontiac ever intended it to be.

The strike’s ripple effects weren’t limited to Pontiac. Norwood built both Firebirds and Camaros on the same line, so Chevrolet’s pony car took a comparable hit that same year. Across General Motors, 1972 is remembered by collectors as one of the strangest model years in muscle car history — not because the cars themselves changed dramatically, but because labor disputes, a shift in how horsepower was measured, and looming emissions rules collided in the same twelve months and left the surviving cars with an unusually tangled paper trail.

About the Video

The episode is the latest from Cars, Shops & Collections, a YouTube series that profiles car owners in their own garages rather than at a sanctioned car show. Host JC Fernandez travels to Boulder City, Nevada to meet up with a recurring subject nicknamed Pontiac Ed, whose collection the show had already covered once before. In that earlier episode, Ed showed off a 1970 Pontiac Judge, a 1978 Trans Am, and a 1999 30th Anniversary Trans Am. Just three weeks after that shoot, Ed picked up the 1972 Formula 400 featured here, and the crew turned around and drove back out to film it before the ink on the title was dry.

What follows is less a walkaround than a conversation — Ed explains how he stumbled onto the car, why the Formula’s dual-snorkel hood and understated badging won him over, and how this latest purchase connects back to his earlier Trans Ams and a relationship with noted restorer Dave Hall of Restore a Muscle Car. The video also teases Ed’s next project, a 1972 Pontiac Le Mans convertible, suggesting this Formula is just one stop in an ongoing collecting habit rather than an endpoint. The format gives the car room to breathe in a way a typical auction-block walkaround never does — viewers get the backstory of how it was found, not just a rundown of options and condition.

Why the Horsepower Numbers Don’t Tell the Whole Story

Anyone cross-shopping a 1972 Firebird spec sheet against a 1970 or 1971 model will notice the horsepower figures look lower, and it’s tempting to blame emissions strangulation. The real explanation is more about paperwork than performance: 1972 was the year the entire American auto industry switched from gross horsepower ratings, measured on a stripped engine with no accessories attached, to the SAE net standard, which measured the engine as it actually sat in the car, driving the alternator, exhaust system, and everything else. A lot of the “lost” horsepower on paper was never really there to begin with — it was a more honest number, not a weaker engine. The Formula’s 400-cubic-inch V8 still pulled plenty of real-world torque, which is part of why cars like Ed’s remain desirable instead of being written off as the weak link of the muscle car era.

That same transitional, slightly confused moment in Pontiac’s history is exactly what made the 1972 Firebird lineup compelling to collectors decades later. It sat at the intersection of a labor dispute that nearly killed it, a horsepower-rating change that made it look weaker than it was on paper, and a production run small enough that survivors are genuinely hard to find in good condition today. The comments under the video make clear this isn’t a niche appreciation, either — multiple viewers describe cross-shopping new Firebirds against GTOs and other Pontiac performance cars back when these were showroom options rather than collector pieces, with at least one describing trading in a 1969 GTO convertible for a brand-new Formula 400 the moment the 1970-and-a-half restyle hit dealer lots.

It’s worth noting that exact horsepower ratings for 1972 Formula 400s vary by source and by the specific engine code a given car was built with, since Pontiac offered more than one 400-cubic-inch variant that year. Rather than repeat a single number that different registries dispute, the safest summary is the one collectors generally agree on: real-world output stayed strong even as the posted figures dropped, and the rating-method switch explains most of that gap.

One of Just 5,250 Built

For Pontiac Ed, the appeal boils down to the details: the twin-scoop hood design that multiple commenters single out as one of the best-looking hoods Pontiac ever cut, the Formula’s position as the sleeper of the Firebird lineup, and the connection it gives him to a wider circle of Pontiac collectors and restorers he’s built relationships with over years of showing his cars. It’s not the rarest Pontiac in absolute terms from that model year — Trans Ams from the same troubled production run, of which only around 1,286 were built in 1972, hold that title — but a Formula 400 that survived both a 174-day strike and five decades of ownership afterward is still a genuine find.

The desert setting matters more than it might seem. Boulder City sits in one of the driest corners of the Southwest, and cars that spend their lives there tend to avoid the rust that eats through Rust Belt survivors within a decade or two. A 1972 Firebird that never saw road salt has a real shot at keeping its original sheet metal and floors intact, which is a big part of why cars like Ed’s can still be found in restorable, sometimes original, condition more than fifty years after they left Norwood. It’s a quieter kind of luck than surviving a factory strike, but it matters just as much to whether a car like this is still around to film at all.

What makes the story land for longtime fans isn’t just the rarity number, it’s how close the whole second-generation Firebird platform came to never getting a chance to earn that rarity in the first place. Had GM’s leadership decided in 1972 that the Norwood strike and the cost of scrapping unfinished cars weren’t worth absorbing, there would be no 1973 Super Duty 455, no late-1970s Trans Am sales boom fueled by a certain black Bandit car, and no decades-long collector market for any of it. Every Formula 400, Trans Am, or base coupe built after 1972 exists in part because GM chose to keep building rather than cut its losses mid-strike. That context is easy to lose when a car is reduced to a spec sheet, and it’s the kind of detail a garage conversation like this one is built to surface.
