The 1970 Chevrolet Chevelle Malibu SS LS6 is a true icon of American performance. Built at the Arlington, Texas, assembly plant, this example has remained with the same owner for 55 years. It combines original charm with significant upgrades, creating a powerful and historically rich muscle car ready for its next chapter.
Classic Design and Provenance
Originally finished in Gobi Beige with black stripes, the Chevelle was repainted around 2005 and fitted with a new Dark Gold vinyl roof. Hood pins and SS badging maintain its bold, period-correct look. Sold new through City Motors in Great Falls, Montana, it later received a dealer-installed 454ci LS6 V8 under warranty, cementing its legendary status among enthusiasts.
Restoration and Attention to Detail
The restoration process was handled with care, focusing on authenticity and performance. A 2005 rebuild saw the engine bored .060 over and upgraded with Edelbrock cylinder heads and a Winters intake manifold. The work preserved the LS6 character while enhancing drivability and reliability.
Power and Performance
At its heart lies a 454 cubic-inch LS6 V8 rated at 450 horsepower, paired with a Muncie M22 four-speed manual transmission. The drivetrain sends power through a Positraction differential, delivering the controlled aggression that defined Chevrolet’s golden era. The dual exhaust system, now fitted with an X-pipe and Magnaflow mufflers, produces a deep and authentic tone.
Engine and Mechanical Highlights
Recent servicing included installation of a COMP Cams camshaft, Melling high-volume oil pump, and new gaskets. The engine also received a Holley carburetor, HEI distributor, and updated mechanical fuel pump. These refinements ensure smooth performance without sacrificing the raw power that made the LS6 legendary.
Chassis and Handling
The Chevelle rides on 15-inch Super Sport wheels wrapped in BFGoodrich Radial T/A tires. Power steering and power-assisted front disc brakes make it more manageable while preserving its period feel. A recent brake service replaced the master cylinder, pads, shoes, and wheel cylinders, ensuring reliable stopping power.
Interior and Driving Environment
Inside, the car retains its gold cloth and vinyl bench seats, complemented by a black dashboard and SS steering wheel. The cabin reflects an authentic 1970s atmosphere, complete with original gauges, a 120-mph speedometer, and a 6,500-rpm tachometer. Though the radio is inoperative, the driving experience remains immersive and mechanical in nature.
Documentation and Provenance
This Chevelle comes with manufacturer’s literature, a partial copy of the build sheet, and 1970-dated LS6 cylinder heads. It also includes removed components and a clean Montana title. The attention to documentation reinforces its authenticity and long-term care.
Summary
The 1970 Chevrolet Chevelle Malibu SS LS6 stands as one of the most celebrated muscle cars ever built. With its 454ci power, four-speed manual transmission, and 55-year ownership history, it offers a rare blend of originality and performance, a timeless representation of Chevrolet’s peak muscle era.
