The 1970 Chevrolet Chevelle LS6 marked the high-water line of the muscle car era. In factory form, it combined brutal torque with surprising street civility. This triple black example, finished in Tuxedo Black over a black interior, reflects the model at its most menacing. Chevrolet built it at the Kansas City plant during peak LS6 production.
LS6: The Ultimate Chevelle
Chevrolet introduced the LS6 as the most potent evolution of the Mark IV big-block. Solid lifters, a high-lift cam, and 11.25:1 compression defined its character. A single Holley four-barrel carburetor sat atop an aluminum intake manifold. Rectangular-port heads and forged internals ensured durability at high rpm.
Factory ratings listed 450 hp and 500 lb-ft, figures widely considered conservative. Contemporary testing suggested real output exceeded published numbers.
Performance and Drivetrain
The 454 cubic-inch V-8 produced 450 hp (456 PS) and 500 lb-ft (678 Nm) of torque. Power delivery feels immediate, with massive midrange thrust. An M40 Turbo Hydra-Matic three-speed automatic channels output to a 4.10 Positraction rear axle. Short gearing transforms throttle inputs into relentless forward motion. Independent front suspension and a solid rear axle manage the load. Power steering and power brakes make the package usable on modern roads.

Interior and Equipment
Inside, bucket seats and a center console define the SS layout. Black vinyl upholstery complements the triple black exterior theme. Round gauges sit ahead of the driver, offering clear readouts at speed. The cowl induction hood feeds cooler air under load. Details such as 5-spoke SS wheels and Goodyear Polyglas tires reinforce period correctness. A Certificate of Authenticity and LS6 Registry listing support provenance.
Production, Pricing, and Collector Trends
Chevrolet produced 4,475 LS6-equipped Chevelles for 1970. That figure represents a small fraction of total Chevelle output. Base MSRP for an LS6 Chevelle started around $3,800 before options. Today, documented examples command six-figure values depending on condition and originality.
Factory performance figures reflect period standards and testing methods. Vehicle condition and setup may influence real-world results today. This Kansas City-built triple black car crosses the block at Glendale 2026. Its specification captures the definitive expression of big-block Chevelle performance.
