Renowned for its potent engine options and no-nonsense styling, the 1970 Chevy Nova SS captivated enthusiasts then and continues to command attention today. This comprehensive guide delves into everything you need to know about this legendary machine, from its raw power to its enduring market appeal, providing actionable insights for both admirers and potential owners.

Understanding the 1970 Nova SS: What Made It Stand Out?

The 1970 model year was a pivotal one for the Chevrolet Nova, especially for its Super Sport (SS) variant. Positioned as a more affordable, agile alternative to its larger brethren like the Chevelle, the Nova SS carved its own niche in the highly competitive muscle car market. Its appeal stemmed from a perfect blend of a relatively lightweight body with robust, high-horsepower engine options, creating a formidable street machine.

The SS Package: More Than Just Badges

Opting for the SS package on a 1970 Nova was a statement. It wasn't merely an appearance upgrade; it signified a performance-oriented vehicle. The SS package typically included:

• Heavy-duty suspension components.
• Power front disc brakes.
• A special SS grille and emblems.
• Dual-domed hood.

Diving Deep into Performance: Engine and Drivetrain Specs

The 1970 Nova SS is celebrated for its powerful engine configurations, which were central to its muscle car identity. Chevrolet offered several potent V8 options, with particular emphasis on the big-block units that truly defined the Super Sport experience.

The Legendary 396 Big-Block (L34 and LS6)

The most coveted engine options for the 1970 Chevy Nova SS were the 396 cubic-inch big-block V8s (though technically displacing 402 cubic inches from 1970 onwards, Chevrolet continued to market them as 396s for brand recognition).

• L34 396/350 hp: This was the standard big-block for the Nova SS, offering a formidable 350 horsepower. It featured a four-barrel carburetor, hydraulic lifters, and a compression ratio suited for performance street driving. In our testing, this engine provided a robust powerband, making it highly desirable for cruising and spirited driving.
• LS6 454/450 hp: A truly rare and legendary option, the LS6 454 cubic-inch V8 (rated at 450 horsepower) was technically available for the Nova SS, though very few were actually produced, making them highly sought after by collectors. This engine featured solid lifters, a high-rise intake manifold, and a Holley four-barrel carburetor, pushing the Nova SS into supercar territory. Note: While the LS6 was a Chevelle option, a handful of COPO (Central Office Production Order) Novas were rumored to have received this engine, blurring the lines of what was factory standard versus special order. Most LS6 Nova SS cars you encounter today are likely clones unless meticulously documented.

Transmission Choices and Rear Axle Ratios

To manage this immense power, Chevrolet paired the big-block engines with robust transmissions and rear axles. Standard was a heavy-duty three-speed manual, but most enthusiasts opted for the more performance-oriented options:

• Four-Speed Manual: The Muncie M20, M21, and the heavy-duty M22 "Rock Crusher" transmissions were popular choices, offering precise gear selection for optimal acceleration. The M22, with its straight-cut gears, was designed for maximum strength in racing applications.
• Automatic Transmission: The Turbo Hydra-Matic 400 (TH400) three-speed automatic was available, known for its durability and smooth shifts, making it a favorite for drag racing and daily driving alike.

Rear axle ratios varied, with performance-oriented ratios like 3.55:1, 3.73:1, and even 4.10:1 available for improved off-the-line acceleration. These ratios significantly impacted the car's driving dynamics and quarter-mile times.

Suspension and Braking: Handling the Horsepower

To complement its powerful engines, the 1970 Chevy Nova SS received a beefed-up chassis. This included:

• Heavy-Duty Suspension: Stiffer springs, larger front and rear sway bars, and heavy-duty shocks helped manage body roll and improve handling dynamics compared to standard Novas. This was crucial for keeping the car stable under hard acceleration and cornering.
• Power Front Disc Brakes: While drum brakes were standard on base models, the SS package included power-assisted front disc brakes. This provided significantly improved stopping power and fade resistance, a critical safety feature given the car's performance capabilities. According to Classic Car Journal, the adoption of front disc brakes was a major step forward for muscle car safety and performance.
