Carroll Shelby didn’t build the 1965 Ford Shelby GT350R to be comfortable. He didn't even build it to be "nice." If you’ve ever sat in a real one—not a tribute, not a kit car, but one of the original 34 production models—you know it smells like high-octane fuel and hot oil. It’s loud. It vibrates until your teeth ache. It was basically a middle finger to the European racing establishment from a Texan who knew how to make a Mustang scream.
Ford had a problem in the mid-sixties. The Mustang was a massive hit, sure, but it was viewed as a "secretary's car." It had zero street cred on the track. Lee Iacocca knew that if he wanted the Mustang to be taken seriously by people who actually cared about driving, he needed a win. Not just a win at a local drag strip, but a dominant performance in SCCA (Sports Car Club of America) road racing. He called Carroll. Shelby's response was classic: "Lee, you can't make a racehorse out of a mule." But they tried anyway.
The result was the GT350, and specifically, the "R" model—the competition spec. While the street version was already a handful, the 1965 Ford Shelby GT350R was a stripped-down, lightweight monster designed for one thing: winning the SCCA B-Production championship. It did exactly that. In fact, it didn't just win; it embarrassed the Corvettes it was supposed to be competing against.
The Anatomy of a Competition Beast
What makes an "R" different from a standard 1965 Shelby? Honestly, a lot more than just some badges. Shelby American took the stock K-code 289 cubic inch V8 and massaged it until it breathed fire. They swapped the stock intake for a high-rise aluminum manifold and tossed on a massive Holley four-barrel carburetor.
They weren't messing around with the cooling either. They threw in a big aluminum radiator and an oil cooler that looked like it belonged on a semi-truck. The engine was rated at 350 horsepower, which sounds modest today when a Camry has nearly 300, but in a car that weighed next to nothing? It was a rocket.
You have to remember how light these things were. They pulled out the sound deadening. The side windows weren't glass; they were Plexiglass with straps to pull them up and down because heavy window regulators are for people who want to lose. The rear window was replaced with a vented plastic piece to help draw air out of the cabin. There was no heater. No radio. No upholstery on the door panels. Just a roll bar, two bucket seats, and a dashboard that looked like it was wired up in a shed. It was raw.
Suspension and Handling Realities
People think old muscle cars can't turn. The 1965 Ford Shelby GT350R proves that’s a lie. Shelby's team lowered the front A-arms, added a massive sway bar, and installed Koni adjustable shocks. They also threw in a Detroit Locker rear differential.
Driving one is work.

The steering is heavy because there’s no power assist. The brakes—front discs and rear drums—require a leg like a NFL punter to operate effectively. If you're used to a modern Porsche with its PDK gearbox and traction control, the GT350R will feel like a dinosaur. But it’s a dinosaur that wants to eat you. It’s communicative. You feel every pebble through the wood-rimmed steering wheel. You know exactly when the rear tires are about to give up because the whole chassis talks to you in a way modern cars, muffled by electric power steering and soundproofing, simply can't.
The "Flying Mustang" and the Ken Miles Legacy
If you saw the movie Ford v Ferrari, you know Ken Miles. He was the guy who really developed this car. The most famous photo in Mustang history is of Miles at Green Valley Raceway in 1965. He’s driving "5R002," the first GT350R prototype, and the car is literally airborne. All four wheels are off the ground.
That image cemented the "Flying Mustang" nickname.
Miles and the Shelby team spent hours testing at Riverside and Willow Springs. They figured out that the front apron—that fiberglass piece with the large intake hole—didn't just look cool; it kept the engine from melting and provided actual aerodynamic benefits. Most people don't realize that the R-model apron was one of the first truly functional aero pieces on an American production-based car.
They also modified the wheel wells. They flared them out just enough to fit wider American Racing "Torq Thrust" wheels wrapped in Goodyear racing rubber. It gave the car a wider, meaner stance that wasn't just for show. It was about lateral grip.
Why 34 is the Magic Number
Collectors lose their minds over the 1965 Ford Shelby GT350R because of the scarcity. Only 34 production models were built, plus two prototypes. That’s it.
Because they were race cars, many of them were thrashed. They were crashed, blown up, or modified beyond recognition in the 70s and 80s when they were just "old race cars" and not million-dollar investments. Finding one with its original engine and body panels is like finding a unicorn that actually likes humans.

This scarcity is why the 1965 Ford Shelby GT350R is consistently one of the most expensive Mustangs at auction. In 2020, the Ken Miles prototype (5R002) sold for a staggering $3.85 million. Even a "standard" production R-model can easily clear the $1 million mark today.
Common Misconceptions About the "R"
A lot of people think the "R" was just a trim package. It wasn't. It had a different VIN sequence. If you see a 65 Shelby and the owner says it’s an original R-model, check the quarter windows. Real R-models didn't have the plexiglass louvers or the small windows seen on later 66 models; they had solid panels or the specific vented rear glass.
Another mistake: people think they all had the blue Le Mans stripes. While most did, some were delivered in "street" colors or left plain for racing teams to paint their own liveries. Don't assume a car is a fake just because it isn't white with blue stripes, though 99% of the clones out there will be painted that way.
What It's Actually Like to Drive
Let's be real. It’s terrifying.
The 1965 Ford Shelby GT350R doesn't have a modern fuel system, so starting it involves a specific ritual of pumping the gas and praying the Holley carb doesn't flood. Once it fires, the side-exit exhausts—which dump right under your ears—make a sound that is less like a car and more like a low-flying fighter jet.
The clutch is heavy. The four-speed Toploader transmission is notched and requires a firm hand. When you get it on a track, the car feels alive. It wants to rotate. It’s not a car you "point and shoot"; it’s a car you dance with. You lead, it follows, but if you step on its toes, it will throw you into a tire wall.
The heat is the thing that surprises most people. Without insulation and with that massive V8 humming inches from your feet, the cabin becomes an oven. Professional drivers back in the day used to lose ten pounds in water weight during a race. It’s a physical experience.

The Lasting Influence on Ford Performance
You can draw a direct line from the 1965 Ford Shelby GT350R to the modern Mustang Dark Horse or the GTD. Carroll Shelby proved that the Mustang could be a world-class athlete. He took a car built for grocery runs and turned it into a weapon that dominated the SCCA for three years straight.
It changed Ford’s DNA.
Before the GT350R, Ford was "Total Performance" in marketing only. After 1965, they had the trophies to prove it. It gave them the confidence to go after Ferrari at Le Mans. It showed that American engineering wasn't just about straight-line speed; it was about braking, cornering, and endurance.
Buying and Owning: What to Know
If you are in the market for one, you need a specialist. Period. There are more fakes than real ones.
- Check the SAAC Registry: The Shelby American Automobile Club keeps meticulous records. If the car isn't in the registry, it's not real.
- Verify the Numbers: The engine, transmission, and rear end should all have specific date codes and serial numbers that align with the build date.
- Inspect the Body: Look for the specific R-model modifications, like the flared fenders and the modified battery location (which was moved to the trunk for better weight distribution).
- Expect Maintenance: These aren't "set it and forget it" cars. They require constant adjustment. Carbs need tuning, valves need lashing, and gaskets will leak. It’s part of the charm.
Practical Steps for Enthusiasts
If you can't drop seven figures on a real one, there are ways to get the experience.
- Build a Tribute: Many companies sell the fiberglass R-model front aprons and vented rear windows. You can build a very convincing "street R" using a standard 1965 fastback.
- Visit a Museum: The Shelby Heritage Center in Las Vegas or the Revs Institute in Florida often have these cars on display. Seeing one in person is the only way to appreciate the "hand-built" nature of the car.
- Simulator Racing: Modern sims like Assetto Corsa or iRacing have highly accurate models of the 1965 Ford Shelby GT350R. It’s the safest way to see just how hard it is to keep that tail in line coming out of a corner.
The 1965 Ford Shelby GT350R isn't just a car. It’s a moment in time when a group of hot-rodders in Venice, California, decided to take on the world. It’s loud, it’s uncomfortable, and it’s perfect. If you ever get the chance to even hear one start up, don't walk away. Stand there, smell the unburnt fuel, and listen to the sound of American racing history.
