The Legend in Green: The 1970 Baldwin/Motion Phase III Chevelle LS6

Some cars are restored. Some are preserved. And then there are the handful that become legends.

This is one of them.

Bearing V.I.N. 136370B133148, this 1970 Baldwin/Motion Phase III Chevelle LS6 Coupe is far more than an exceptionally rare muscle car. It is a surviving time capsule from the most outrageous era in American performance, showing a remarkable 1,878 original miles from new. Even more impressive, its history is supported by an extraordinary documentation portfolio, including a copy of the original title, the original Chevrolet Dealer Invoice, the Motion Performance Invoice, and multiple original Build Sheets—the kind of provenance collectors dream of finding.

Adding to its extraordinary pedigree, this Chevelle was formerly part of the prestigious Otis Chandler Vintage Museum Collection, where only the finest and most historically significant automobiles earned a place among one of the world’s greatest collections.

In 1970, Chevrolet unleashed the mighty LS6 454—a factory powerhouse officially rated at 450 horsepower, though enthusiasts knew the true figure was considerably higher. For most buyers, that was enough.

For the select few who wanted something no ordinary dealership could provide, there was only one destination: Baldwin Chevrolet and Motion Performance.

Joel Rosen and Motion Performance had built a reputation unlike anyone else in America. They didn’t simply sell muscle cars—they transformed them into street-legal supercars capable of embarrassing exotic European machinery and dominating drag strips across the country.

This Chevelle became one of those elite creations.

After arriving from Chevrolet, the LS6 received the coveted Phase III 454 Package, elevating it into one of Motion’s most feared street machines.

Backing the legendary big block is the bulletproof M22 “Rock Crusher” Heavy Duty 4-speed transmission, sending immense torque to a rear axle fitted with aggressive 4.88/5.13 gears, a combination built for breathtaking acceleration.

To harness that explosive power, Motion equipped the car with:

Ladder Bars

Side Exhaust

Hood Locks

Hone-a-Matic performance system

Alarm system

Every addition reflected Motion’s philosophy: if it made the car quicker, stronger, or more intimidating, it belonged.

Despite its race-inspired hardware, this Phase III wasn’t stripped for battle.

Instead, it was ordered with an impressive list of luxury equipment:

Power Steering

Power Brakes

Power Windows

Bucket Seats

Center Console

Wood Sport Steering Wheel

Factory Tachometer

AM/FM Radio

Rear Speaker

Rear Defroster

It offered the comfort expected from Chevrolet’s premier muscle coupe while hiding one of the most formidable drivetrains ever assembled.

Perhaps the most astonishing feature isn’t the horsepower.

It’s the mileage.

Only 1,878 original miles have accumulated since this remarkable Chevelle first rolled onto American roads.

Cars like this were rarely spared. Most Baldwin Motion Chevelles were driven hard, raced regularly, modified extensively, or simply disappeared over time.

This example escaped that fate.

Its preservation eventually earned it a place within the renowned Otis Chandler Vintage Museum Collection, one of the most respected assemblages of historically important automobiles ever created. That inclusion alone speaks volumes about the significance of this Phase III Chevelle.

The paperwork accompanying this car tells its story almost as vividly as the car itself.

Included are:

Copy of the Original Title

Original Chevrolet Dealer Invoice

Original Motion Performance Invoice

Multiple Original Build Sheets

Together, these documents authenticate the car’s remarkable history and provide collectors with the confidence that accompanies truly elite provenance.

Long before the term “supercar” became commonplace, Baldwin Motion was building machines capable of astonishing performance using Chevrolet’s biggest engines and Motion’s uncompromising engineering.

This 1970 Phase III Chevelle represents the absolute pinnacle of that era.

It is the perfect convergence of factory LS6 muscle, Motion Performance engineering, exceptional originality, astonishingly low mileage, museum pedigree, and comprehensive documentation.

For collectors, opportunities to acquire an authentic Baldwin Motion Phase III are extraordinarily rare.

To find one with 1,878 original miles, extensive factory and Motion documentation, and former ownership in the Otis Chandler Vintage Museum Collection places this Chevelle among the most significant surviving examples of America’s golden age of high-performance automobiles.

It is more than a muscle car.

It is a benchmark.

A survivor.

A museum-quality icon.

And a reminder of a brief moment in history when horsepower ruled the streets, Motion Performance rewrote the rules, and legends like this were born.
