Numbers-Matching 455 V8

This stunning 1970 Buick GS 455 combines Buick's legendary big-block performance with an exceptionally rare and attractive Aquamist exterior over Pearl White interior color combination.

Showing 57,273 miles, this GS has undergone a recent frame-up restoration while retaining important original components, including its numbers-matching 455 V8 and Turbo-Hydramatic 400 automatic transmission. The car also retains its original rear axle and is accompanied by Sloan Museum documentation supporting its history.

With its muscular styling, distinctive color combination, documented provenance, and legendary 455 power, this is an impressive example of Buick's contribution to the golden age of American muscle.

At the heart of this GS is its numbers-matching Buick 455 cubic-inch V8, backed by the original Turbo-Hydramatic 400 automatic transmission.

The 455 was the centerpiece of Buick's performance lineup in 1970, delivering the effortless low-end torque and smooth power that made the GS 455 such a formidable muscle car.

Mechanical features and recent work include:

Numbers-matching 455 CID V8

Numbers-matching TH400 automatic transmission

Original 8.2-inch rear axle

2.93 rear gears

Professionally rebuilt carburetor

Lectric Limited electronic/pointless distributor conversion

New engine wiring harness

New front lighting harness

Strong-running drivetrain

The engine is reported to run well, making this GS equally suited to cruising, shows, and weekend enjoyment.

Recent Frame-Up Restoration

The car has undergone an extensive frame-up restoration, addressing the body while preserving original sheet metal wherever practical.

Body restoration included:

New partial rear quarter panels

New outer rear wheelhouses

New cowl

New floor pans

Original doors

Original front fenders

Original hood

Solid frame

Solid trunk

The result is a clean, properly presented GS that retains important original components while benefiting from substantial restoration work.

Rare Aquamist & Pearl White Combination

One of the defining characteristics of this particular GS is its striking Aquamist exterior paired with a Pearl White interior.

According to the information accompanying the car, only 164 examples were produced in this exterior color, with considerably fewer believed to have been paired with the Pearl interior.

The combination gives the GS a very different character from the darker and more commonly encountered muscle-car colors of the period.

Restored Pearl White Interior

The interior has been extensively refreshed while maintaining the classic appearance of the 1970 GS.

Interior improvements include:

New Legendary upholstery

New carpeting

Pearl White seating

Refreshed instrument panel

LED instrument lighting

New auxiliary under-dash gauges

Classic Buick GS interior appointments

The light interior contrasts beautifully against the Aquamist bodywork and gives this GS a particularly distinctive presentation.

Factory Air Conditioning

The car is equipped with a complete factory air-conditioning system. The components remain present, although the system will need to be serviced and converted or updated for use with modern refrigerant before being placed back into operation.

Wheels, Tires & Glass

The GS rides on classic Buick-style wheels with new tires.

The rear wheels measure 15x8 and present very well, while the 15x7 front wheels show a few small areas of pitting.

The car has also received new smoked glass from American Auto Glass. Its original green-tinted factory glass has been retained and can be included with the vehicle if desired.

Sloan Museum Documentation

An important addition to this GS is its available Sloan Museum Buick microfilm documentation.

The documentation records VIN 44637-0H-121734 and identifies the original dealer as Russell B. Case & Son of Manasquan, New Jersey. The record also shows an original invoice amount of $3,813.17, along with factory color, trim, order, body and dealer information.

For a classic Buick of this caliber, this documentation provides valuable historical provenance that complements the car's numbers-matching drivetrain and restoration.

A Distinctive Buick Muscle Car

With its numbers-matching 455 V8 and TH400 transmission, recent frame-up restoration, rare Aquamist and Pearl White combination, factory air conditioning, refreshed interior, new glass, new tires, solid structure, clean title, and Sloan documentation, this GS offers an impressive combination of performance, presentation, originality, and provenance.
