1970 Chevrolet Chevelle SS LS6 | Matching Numbers 454/450 HP | Build Sheet

The Overview

The Pinnacle of the Muscle Car Era. At Greg’s Classic And Performance, we understand that for serious collectors, one number stands above the rest: LS6. This 1970 Chevrolet Chevelle SS represents the absolute peak of GM performance, featuring the legendary 454 cubic inch V8 factory rated at 450 horsepower.

This is not just a tribute; this is a Matching-Numbers LS6 backed by a 4-Speed Manual Transmission. Finished in factory-correct Fathom Blue with White Rallye Stripes, this example is particularly special due to its high degree of originality, retaining its original sheet metal, original body, and even some of its original paint.

Under the Hood: The Legend

In 1970, Chevrolet took the gloves off. The LS6 was the highest horsepower engine ever offered in a passenger car by Chevrolet during the muscle car wars.

• Engine: Matching-Numbers LS6 454 CI V-8 (450 HP / 500 lb-ft Torque).

• Transmission: 4-Speed Manual Transmission with a floor-mounted Muncie shifter.

• Rear End: 12-Bolt Positraction rear axle, built to handle the massive torque.

• Performance: Equipped with F41 performance suspension as standard SS equipment.

Exterior & Interior

While many Chevelles were black or red, this car wears a stunning and rare color combination.

• Paint: Fathom Blue with White Rallye Stripes (Factory Correct).

• Top: Original Blue Vinyl Top, adding a touch of class to the brute force.
