Revology 1969 Boss 429 Mustang First Test: Go Ahead, Meet Your Heroes

Meet the new Boss. Not the same as the old Boss.

It’s nearly impossible to overstate the Ford Mustang’s impact on American culture, and classic Mustangs—model years 1964.5 to 1973—loom especially large in our collective imagination. You need look no further than Ford’s own hard turn into retro Mustang styling and the resulting success for proof of that.

But the reality of living with a classic Mustang tends to dump cold water on the fantasy. Break out the pitchforks and torches if you must, but we don’t mind telling you—and we’ve owned enough of them to know from whence we speak—the first Mustangs were never that great, even by the standards of their day, and are objectively terrible by any current standard, except perhaps for that of beauty.

Their brakes are weak (and single circuit, at least until 1967), their cooling systems are often inadequate, and their steering is about as sharp as a cargo freighter’s. They rattle and squeak and flex and bump-steer. Their cowls and windshields leak in the wet, they don’t like to start in the cold, and they vapor-lock when they’re hot. Power? Sure, but less than you might think. And power windows? A/C? Overdrive? Double-digit fuel economy? Radio with more than one speaker? Surely you jest.

Yet despite all those flaws, the first-generation Mustang is an absolute icon, a whole much greater than the sum of its parts, a thing of beauty whose loveliness increases. It created the pony car segment, helped usher in a new era of American-style factory performance, and spawned generations of enthusiasts. Which is why there’s a Mustang modification industry nearly as old as the Mustang itself, and why restomods—cars modified to address the limitations of old technology while retaining the original aesthetic appeal—have gained so much momentum over the past few decades. It’s why the Revology Boss 429 exists.

Revising the Legend

The story goes that when Revology’s founder, a Ford enthusiast and former Ford employee, wanted a restomod Mustang built to his own high standard, he soon realized that nothing of the kind existed—so he decided to fix that by founding a firm to bring his vision to life.

Several offerings later, we have the Revology Boss 429, which builds on the legend of Ford’s original NASCAR homologation specials of the same name, and it’s an impressive effort. Revology is quick to point out that its Boss is not in fact a restomod, but rather a sort of clean-sheet reimagining of an original 1969 Boss 429 Mustang, engineered to the standards of the present day but with the character of the original car intact—an attempt to build the ’69 Mustang Ford would have, if it could have.

From the outside, it’s every bit the classic Mustang of your dreams. Credit Ford’s design, of course, but also Revology’s attention to detail. Features like the 17-inch aluminum GT500-style wheels, two inches larger than the original units and shod in modern Michelin Pilot Sport performance rubber, subtly update the looks and lessen unsprung weight without announcing themselves too loudly. LED lighting increases visibility but hews closely to the original look. The point is, you’d have to really scrutinize these details to notice a difference, and that’s exactly how Revology planned it.

Slip inside and the differences become more apparent, though not alarmingly so; all the familiar Mustang interior touches you expect are still present, just elevated. Modified bucket seats sourced from a Mazda Miata do an excellent job of aping the original high-back buckets while providing enhanced comfort and support (hey, actual bolsters!), and they’re covered in full-grain Nappa leather that’s far more luxurious than the original vinyl.

Deep gauge pods and the requisite passenger-side dash clock mimic the design of the originals, but get modern digital function and an attractive American Black Walnut wood veneer surround that becomes even more attractive when you deploy the veneered blanking panel, which swings down to hide the very basic 7-inch touchscreen mounted at the center of the dash. That touchscreen doubles as a backup camera and controls Bluetooth functions, including those of the Harman-Kardon premium sound system. With the panel deployed, you’re left with suitably vintage-looking, manual HVAC controls. How sweet it is.

Meat and Potatoes

All well and good, you may be saying, but how does it perform? You won’t find the original’s namesake behemoth 7.0-liter “semi-hemi” under the hood, but you won’t miss it. Revology’s Boss 429 sports a Roush-tuned, supercharged 5.0-liter Coyote V-8 rated at 710 horsepower and 610 lb-ft of torque, backed up by a Tremec T56XL six-speed manual transmission that routes power to a three-link 8.8 rear axle loaded with a 3.73:1-ratio Traction-Lok differential.

In our testing, this arrangement carried the 3,970-lb Boss from 0–60 mph in 4.2 seconds and through the quarter-mile in 12.1 seconds at 122.5 mph. For context, that’s about 2 full seconds quicker in the quarter than the old Boss could manage. In truth, it’s more power than you need, and sometimes more than the rear tires can handle—“burnout city,” in the words of one MotorTrend test driver—but we trust this won’t, uh, present a problem for the average Revology customer.

And Braking? Handling? Rigidity? Noise? Forget about it. There’s no comparison. Revology tells us that each of these cars starts as a genuine 1969 Mustang, to which a brand-new Sports Roof body shell and a litany of modern manufacturing processes are applied. Framing fixtures, automated welding, structural adhesives, and modern polyurethane-bonded glass yield a level of composure and quiet that is almost unnerving for an old Mustang. Revology’s Boss uses Wilwood power disc brakes at all four corners and an aluminum front subframe to locate tubular control arms and hydraulic rack and pinion steering.

It all makes for a driving experience that’s highly refined but still feels appropriately mechanical and connected. These are the details that separate a showpiece from a real road-tripper, and Revology gets them right. On the highway, with the distracting background chatter of road noise and vibration dialed down, you’re free to focus on the car’s numerous pleasures. The predictable clutch action, the satisfying shifter feel, the instant throttle response and refined bellow of that supercharged V-8—in hundreds of miles of test driving, it just never got old.

Worth It?

OK, so, it’s very good, but should you buy one? With a starting price of $395,000 ($423,100 as tested), that’s between you and your financial advisor, although you’ll be hard-pressed to find a drivable original Boss for that money, much less a sorted one. What we can tell you is that, cost and collectibility aside, we’d rather own this Mustang than any old Mustang, no matter how nice.

We can tell you this because we’ve experienced the scene we’ll now ask you to picture: You’ve reached the end of a long day, and you’re all alone on a dead-straight stretch of California desert two-lane. The sun is not quite set, and everything is bathed in a pinkish dusklight that seems to make the hide of your Mustang radiate a light all its own. At full gallop, nose pointed at the horizon, exhaust notes buzzing all around you and that broad hood scoop dominating your view over the long hood, it could be 1969. It’s a moment that exists outside of time. You didn’t plan it, but you’re in a car that makes it possible; a car that, given the right light and the right road, can cast a spell on you. This is what we chase as car enthusiasts but rarely catch. It’s the fantasy of classic Mustang ownership without any meddlesome reality, and it can be bought. It doesn’t need to make sense, and once you’ve digested that fact, maybe it makes all the sense in the world.
