1970 Chevrolet Chevelle Has the Full Package: Triple-Black, LS6 Muscle, Matching Numbers

Although Chrysler debuted a 425-horsepower V8 in 1966 (yes, I'm talking about the 426 Hemi), Chevy didn't bother offering something similar. Customers who wanted more oomph had to opt for the Corvette sports car. But that changed in 1970 with the arrival of the 454-cubic-inch (7.4-liter) LS6.

Essentially an LS5 on steroids, the LS6 delivered 450 horsepower and 500 pound-feet (678 Nm) of torque. It was by far the most potent factory engine, placing the Chevelle SS at the top of the muscle car market. It was also the only mill that came close to Buick's 510-pound-foot (691-Nm) rating for the 455-cubic-inch V8 in the GSX.

Unlike most of its high-performance rivals, the Chevelle LS6 was short-lived. Chevrolet chose to discontinue the mill for 1971, so it's a one-year-only model. Records show the company put together 4,475 cars, so it's also somewhat rare. About 500 LS6 vehicles were El Camino pickups, so two-door hardtop production is actually a tad below the 4,000-example mark. 

If you're in the market for one, there's are quite a few examples to choose from. This Tuxedo Black hardtop is one of them and has quite a few things to brag about.

Set to cross the block at Mecum's Glendale 2026 auction, this Chevelle LS6 is a factory triple-black car. What does it mean? Well, it also has a black vinyl top and a black interior in addition to the Tuxedo Black paint. It's not exactly pitch-black, though. Like any LS6, it has twin white stripes running across the hood and trunk lid.

But it's more than just a restored classic that looks good. It's also packing a numbers-matching drivetrain, which is a pretty rear feat. It's not a holy-grail four-speed manual car, but the automatic transmission and the 4.10 Posi rear end will provide lots of fun at the drag strip.

The Chevy was also ordered with power steering and power brakes, and includes the desirable cowl induction hood, bucket seats, and center console. The Chevelle is listed in the official LS6 Registry and comes with a certificate of authenticity. 

How much will it go for? Mecum doesn't provide an estimate, but a quick VIN check reveals that the hardtop was listed for $139,995 in October 2025. That's in line with the current average auction price for LS6 cars in this condition, but I wouldn't be surprised to see it cross the block for more.

As of this writing, the world's most expensive LS6 hardtop sold for $440,000. It sports the same Tuxedo Black color, but it has the more desirable four-speed manual. A red example sold for the same amount a few years back. In all, eight hardtops fetched over $250,000 at public auctions in recent years.

The convertible, on the other hand, is way more expensive (mostly because it's also much rarer). Five examples sold for over $500,000 since 2022, with the all-time record set at a whopping $770,000 at Kissimmee 2026. This hardtop will hit the stage on March 21. How much will this triple-black gem go for? Let me known in the comments.
