This 1967 Ford Mustang Fastback pushes the definition of a “restomod” to its absolute limit. What began as a classic Mustang now exists as a full tube-chassis, race-bred machine with virtually no original Ford components remaining. Built for serious track use yet somehow street-driven, this wild creation blends old-school muscle aesthetics with hardcore motorsport engineering.
Owned and refined over 15 years, this Mustang delivers a raw, visceral driving experience backed by NASCAR-derived power and fully custom fabrication throughout.
Exterior
At first glance, the car retains the unmistakable silhouette of a 1967 Mustang—but that’s where the resemblance ends. The entire body is constructed from lightweight fiberglass, including the roof, with only the windshield trim remaining from the original car.
Aggressive widebody fender flares extend approximately 4.5 inches in the front and 6 inches in the rear, giving the car a planted, race-ready stance. The rear styling draws inspiration from early turbocharged race cars, while Lexan rear glass and a glued-in front windshield emphasize its track-focused design.
Custom 17-inch wheels (17×9.5 front, 17×12 rear) wrapped in 275 front and massive 315 rear tires complete the purposeful look.
Interior
Inside, the Mustang is all business. The stripped-down cockpit features lightweight race seats, a full roll cage, and a functional layout designed for performance driving.
A race-spec switch panel, AutoMeter gauges, and a fire suppression system highlight its competition roots. The Wilwood pedal box and adjustable brake bias system provide precise control, while the minimalist approach reinforces its track-first philosophy.
Despite its hardcore setup, the cabin remains surprisingly usable for street driving, offering just enough comfort to make short drives manageable.
Engine & Performance
Power comes from a former NASCAR engine originally built in the late 1990s. Starting as a 358 cubic-inch V8, it has been bored and stroked to 408 cubic inches.
Key engine features include:
- D3 cylinder heads
- Full roller camshaft and valvetrain
- Dry sump lubrication system
- 15:1 compression ratio (race fuel required)
Output is an astonishing 800+ horsepower, with the engine capable of exceeding that figure under more aggressive tuning.
A four-stage dry sump system ensures reliability under extreme conditions, while an Accusump system pre-lubricates the engine during startup to prevent wear.
Drivetrain & Chassis
This Mustang rides on a fully custom tube chassis with entirely hand-fabricated suspension components.
Key highlights include:
- Custom short-long arm (SLA) front suspension
- Rack-and-pinion steering from a Fox Body Mustang
- Tremec TKO 500 5-speed manual transmission
- Independent rear suspension sourced from a late-1990s Mustang Cobra
- Fully custom control arms and axle shafts
The car features near-perfect 51/49 weight distribution, aided by a centrally mounted 20-gallon fuel cell.
Braking is handled by AP Racing components up front and Wilwood units in the rear, delivering serious stopping power.
Driving Experience
On the road—and especially on track—this Mustang behaves exactly as you’d expect: like a race car. Steering is immediate, grip is immense, and body roll is virtually nonexistent.
Despite its extreme setup, the car remains surprisingly composed at lower speeds, allowing for street driving when needed. However, it truly comes alive under acceleration and in corners, where its motorsport pedigree shines.
Drivers describe the experience as raw and engaging, requiring skill and input—rewarding those who can extract its full potential.
Key Takeaways
- Full tube chassis with fiberglass body
- NASCAR-derived 408ci V8 producing 800+ hp
- Fully custom suspension and independent rear setup
- Track-focused build with street-driving capability
- Near-perfect weight distribution (51/49)
- Raw, race-inspired driving experience
Conclusion
This 1967 Ford Mustang Fastback is far from a traditional restoration—it’s a purpose-built machine that blurs the line between race car and street car. With NASCAR power, bespoke engineering, and aggressive styling, it stands as one of the most extreme interpretations of a classic Mustang.
For enthusiasts who value performance above all else, this build represents the ultimate expression of what a vintage Mustang can become.
