Videos: Restoring v Restomodding a 1965-1973 Ford Mustang - You Decide

Few cars command respect like the 1965–1973 Ford Mustang. Whether it’s a ’65 fastback 289, a Boss 302, a rare and racy Shelby Mustang, or a Mach 1 big block, these icons of American muscle never fail to turn heads.

But once you’ve tracked down your dream project—maybe a dusty barn find or a half-finished Craigslist special—you’re faced with one big decision:

Do you restore it to factory specs, or build a modernized restomod beast?

Bringing It Back to Factory Fresh

A restoration is all about authenticity. The goal is to return your Mustang to exactly how it left the factory—right down to the date-coded glass, Autolite battery topper, and red oxide primer on the floor pans.

• KK no. 2100
• 1 of 499 produced for 1970
• Comprehensive restoration with approximately 455 miles since completion
• Correct factory markings
• Desirable color combination of Grabber Blue paint and White decor bucket seats
• Boss 429 CI 4V V-8 engine
• Rated at 375 HP
• Close ratio 4-speed manual transmission
• 3.91 Traction-Lok axle ratio
• Power steering
• Power brakes with front discs

You’re not customizing; you’re preserving history. Every part, every finish, and every bolt should be true to the original Ford spec.

OEM Parts and Original Specs

True restorers live for OEM, NOS, and accurate reproduction parts. The carbureted small block stays, the drum brakes get rebuilt, and the AM radio crackles with vintage charm.
If you’re chasing MCA concours gold or aiming to impress the purists at your next car show, restoration is your route.

Driving a restored classic Mustang is like stepping back into 1967. The steering is loose, the brakes take muscle, and the suspension wallows a bit—but that’s the magic. You feel the era in every vibration and every burble from the exhaust.

Value: The Collector’s Gold Standard

In the collector world, originality equals credibility. A numbers-matching restoration, especially for models like the Boss 429, GT350, or Mach 1, can fetch serious money. But tamper with originality—say, a modern engine swap—and purists will mark you down.

Classic Looks, Modern Performance

A restomod (restoration + modification) keeps the vintage vibe but adds modern tech and performance. Think of it as a 1969 Mustang Fastback with the heart of a 2025 GT.

The body stays classic, but under the hood and beneath the sheet metal, everything gets an upgrade.

Performance Upgrades and Powertrain Swaps

• Comprehensive build by Robert Brawn of Gilbert, South Carolina
• 2015 Ford 5.0L Aluminator XS engine
• Tremec Magnum XL 6-speed transmission
• 8.8 rear end with 9-inch Ford axles and 3.73 ratio gears
• Wilwood disc brakes
• Griggs Racing suspension
• Shock towers have been removed
• 1967 Shelby Mustang fiberglass body parts
• Custom interior with recovered Recaro seats
• Rollcage with removable sidebars
• Mustangs to Fear dash and roof panel
• Classic Instruments gauges with custom colors
• Vintage Air
• Sony stereo
• Fire suppression system
• Nardi flat-bottom steering wheel
• Storage under the rear compartment
• J.W. Speaker LED headlights and center lights
• Gulf racing livery
• Kindig-It Design recessed door handles
• Hand-built front wheel flares
• CCW 18x9 and 18x12 wheels

Restomods often get disc brakes all around, rack-and-pinion steering, coilover suspension, and—of course—a serious power upgrade. They're also apt to receive some hi-tech and way cool LED headlights, taillights, and interior lights like the ones blazing a brilliant path ahead in bright daylight just above. A Coyote 5.0L swap is the holy grail of restomod powerplants, bringing fuel injection, reliability, and over 400 horses to your classic.

Other common mods include:

• Modern TREMEC 5-speed or 6-speed transmissions
• EFI conversions to replace carbs
• Aluminum radiators and electric fans
• Custom headers and exhaust systems

The result? A car that looks 50 years old but drives like it rolled off a modern assembly line.

Interior and Comfort Mods

Restomods blend comfort with performance. Expect upgrades like:

• Recaro or TMI Sport seats
• Custom gauge clusters
• Bluetooth audio and hidden speakers
• Vintage Air A/C systems
• LED lighting and push-button ignition

It’s classic style without the compromises.

Driving Experience: Built to Be Driven

Unlike a pure restoration, a restomod isn’t meant to sit under a car cover. It’s made to be driven hard and often. With better handling, braking, and reliability, these builds can easily handle long road trips or weekend track days.

Value: The Modern Collector’s Market

The restomod market is exploding. A well-built Coyote-swapped ’69 Fastback or Pro Touring ’67 GT can command six figures at auctions like Barrett-Jackson. While they may not have historical authenticity, they offer practicality and performance that modern buyers crave.

Restoration vs. Restomod: Key Differences

Which Is Right for You?

Ask yourself a few questions:

• Do you want a piece of history, or a car you can drive anywhere?
• Are you building to show or to go?
• Do you get satisfaction from factory-correct details—or from modern horsepower and performance?

If you live for authenticity, restore it.
If you want to drive it like it’s brand new, restomod it.

There’s no wrong answer—just different philosophies of passion.

Final Thoughts: Every Mustang Has a Soul

Whether you’re chasing concours trophies or cornering G-forces, both restorations and restomods celebrate what makes the Mustang legendary: its freedom, individuality, and mechanical spirit.

From the rumble of a carbureted 289 to the snarl of a modern Coyote, the sound of a classic Mustang will always stir the soul. And no matter your path—purist or performance enthusiast—you’re keeping the legend alive.
