Key Facts

The end of the Big Block era.
The last roar before the silence.

Offered here is an extraordinarily rare and highly desirable 1971 Ford Mustang Mach 1 Fastback 429ci Cobra Jet – J Code, built in September 1970 for the 1971 model year. A genuine export-market car, this example is accompanied by its Marti Report, confirming factory authenticity and original specification.

This is not a tribute.
This is not a clone.
This is real Cobra Jet muscle.

What is the Marti Report?

The Marti Report is the definitive factory documentation for 1967–1973 Mustangs, produced using original Ford production records. It verifies:

• Original engine code (J-Code 429 Cobra Jet)
• Factory colour and trim combinations
• Production date and build sequence
• Options and equipment
• Rarity statistics

For serious collectors, a Marti Report is the gold standard of authenticity. It confirms this vehicle is a genuine factory-built 429 Cobra Jet Mach 1 — not a later conversion.

Condition

This vehicle is a true Japanese barn find, stored away in a rural barn for over 40 years.

While long-term storage preserved its originality, time was not especially kind to the paintwork. As such, the vehicle is currently undergoing:

• Complete strip to bare metal
• Proper correction of any blemishes
• Professional refinishing in its original Ford Wimbledon White with black striping and Mach 1 decals
• New Tires
• Bushes and suspension will be replaced

Importantly, the structure and originality remain intact.

The interior, however, tells a different story.

The correct 5R Clarion Green knit vinyl Mach 1 interior remains in supreme condition, remarkably preserved. Even more telling are the early production (only up to October 1970) single-bar speaker grilles in the door trims — a detail only purists recognise, and one that strongly indicates this car is an untouched, highly original example.

These small, often-overlooked details separate true cars from restored recreations.

The factory export KM/H speedometer remains fitted, and the vehicle shows low kilometres — entirely consistent with its decades-long storage.

Summary

1971 marked the beginning of the end for the true big block muscle car era.

The 429 Cobra Jet was among the last of Ford’s brutal, high-compression, big-cube factory performance engines before emissions regulations and insurance pressures changed everything.

The J-Code 429 Cobra Jet delivered massive torque, unmistakable big block presence, and raw American muscle character that cannot be replicated.

This car represents:

• The last generation of factory big block Mustangs
• Verified Cobra Jet authenticity
• Rare export specification
• Genuine barn find provenance
• Documented originality

Muscle cars today are plentiful.

Real, documented, export 429 Cobra Jet barn finds are not.

This is blue-collar thunder from the golden age of horsepower.

Equipment and Features

• 429ci Cobra Jet V8 (J-Code)
• Original 4-barrel Rochester carburator
• Heavy-duty cooling package
• Ram Air functional hood system with Plenum and Ram Air Cleaner
• Mach 1 Sports Roof body
• Factory export KM/H speedometer
• Power front disc brakes
• Mach 1 competition suspension
• 5R Clarion Green knit vinyl Mach 1 interior

The 1971 body style brought aggressive proportions — long hood, muscular haunches, and unmistakable presence. Combined with the 429, it delivers one of the most imposing silhouettes of the muscle car era.
