How many 1966 Chevelle SS were made?

In broad terms, the 1966 Chevelle SS 396 was produced in the low tens of thousands, with most credible estimates placing the total around the 20,000 to 30,000 range for the year.

The question asks for an exact tally of how many 1966 Chevelle SS models were manufactured. Chevrolet did not publish a single, definitive year-by-year count for the SS 396 option, so researchers rely on production records, build sheets, and dealer data. Numbers can vary depending on how the SS designation is counted (whether you include only 396-equipped cars, all cars with the SS appearance package, and whether you separate hardtops from convertibles).

Background on the 1966 Chevelle SS 396

The 1966 Chevelle marked the launch of the second generation, with the SS (Super Sport) option continuing to symbolize performance and style. The SS 396 engine remained a centerpiece of the lineup, available across several body styles but produced in comparatively smaller quantities than the overall Chevelle range. Because Chevrolet did not release a straightforward annual SS 396 production total, figures cited by historians and enthusiasts come from compiling factory records and historical data, leading to a range rather than a single absolute number.

Counting methods and sources

Different reference works use varying criteria to tabulate the SS 396 numbers. Some counts focus strictly on cars equipped with the 396 cubic inch engine, others include any car carrying the SS appearance package even if the engine differed, and some break counts down by body style (hardtop, coupe, convertible). This methodological variation explains why published totals differ among reputable sources.

Estimated range and what it means

Based on available production records, GM Heritage Center data, and contemporary automotive databases, the consensus range for 1966 SS 396 production falls roughly between 20,000 and 30,000 units for the year. Exact counts by body style are not universally agreed upon, and the same car could be counted differently by different researchers.

Summary

There is no single official tally for the number of 1966 Chevelle SS 396 cars built. The best-supported estimates place production in the low-to-mid tens of thousands, typically cited as about 20,000–30,000 units, with slight variations depending on counting conventions and data sources. For the most precise figures, researchers consult the GM Heritage Center, Chevrolet historical records, and dealer-build data, while noting that estimates may differ slightly between sources.

How can you tell if a 1966 Chevelle is a real SS?

To tell if a 1966 Chevelle is a real SS, check the VIN, which should start with 138 for an SS 396 model. Look for other authenticating features like an SS-specific blacked-out grille, non-functional raised vents on the hood, and distinctive "SS" emblems on the front and back. You can also verify originality with the build sheet or Protect-O-Plate, which list the car's original factory options.

• Vehicle Identification Number (VIN): The VIN is the most critical identifier. For a 1966 Chevelle, the first three digits must be 138 to indicate it was an original Super Sport. The VIN is typically located on the driver's side door jamb, and for a 1966 SS 396, the VIN on the door jamb will also have a body style code of 17, making the beginning of the VIN 13817. 
• Exterior Features:
  • Grille: A blacked-out grille is a signature SS feature, though it may have been changed on restored cars. 
  • Hood: Look for non-functional, raised "power dome" vents on the hood, which were exclusive to the SS 396 models. 
  • Emblems: Check for the correct "SS" badging on the front and rear of the vehicle. 
• Documentation:
  • Build Sheet: The most definitive proof is the original build sheet, which lists all factory-installed options. If available, this is the best way to confirm authenticity. 
  • Protect-O-Plate: This is a metal plate provided by GM that contains important original information about the car, such as the engine, transmission, and rear axle codes. 
• Interior and Mechanicals:
  • Engine: The VIN should correspond to the original engine, which for the SS 396 was the 396 cubic inch V8. 
  • Interior: Authentic SS models typically came with bucket seats and a center console, although a bench seat was also an option. 
  • Rear End: While a 12-bolt rear end was standard on the SS 396, it was also available on other models, so it's not a sole identifier. 
  • Frame Reinforcement: The rear frame also had a special reinforcement piece, standard on the 396, but could also be ordered on other models. 
  • Special Details: Look for details like specific trim on the bucket seats or original date codes on the engine and other parts.

What is the rarest 1966 Chevelle SS option?

The L34 396 engine always made it desirable, but with over 24,000 Chevelles made with this option, not so rare. The power windows and four-way bucket seats are another story. Only 3,164 1966 Chevelles were ordered with power windows and even fewer (only 587), with four-way bucket seats.

How many 66 Chevelle SS were made?

More than 447,000 Chevelles were built for the 1966 model year. Of them, more than 66,000 were the Sport Coupe SS 396. Just 5,429 SS396 convertibles were produced, but only 100 Chevelles were produced with the L78, making them highly desirable.

How much is a 1966 Chevelle SS worth?

The value of a 1966 Chevelle SS varies widely, typically ranging from approximately $40,000 to $80,000 for average to good condition cars, but can go much higher for exceptional examples. Factors like its condition, engine (especially the original 396396396), and historical significance, like a "real" SS trim (VIN starting with 138), significantly impact the price. A prime, perfectly restored original car could be worth over $100,000, while a project car might sell for less than $40,000.
 
Factors that influence value

• Condition: A car's overall condition—from its paint and body to its mechanical and interior state—is a major factor in its value. 
• Originality: Matching numbers (original engine and transmission) significantly increase a vehicle's value compared to a car with swapped parts. 
• Trim level: Being a "real" Super Sport (SS) is crucial. A VIN starting with "138" indicates a true SS model, which is more valuable than other Chevelle trims. 
• Engine and options: The original 396396396 engine is a key feature, and rare or desirable factory options (like power windows, special gauges, or air conditioning) can also add to the price. 
• Mileage: While less important for classic cars than condition, a low mileage on an original vehicle can increase its value. 
• Body style: Hardtop and convertible models will have different values. 
• Market demand: The value is also influenced by current market trends and specific buyer interest in a particular model.

Sample value ranges

• Average Condition: Around $54,950$ 54 comma 950$54,950 for a 396396396 in good condition with average specs. 
• High Value: Up to $88,500$ 88 comma 500$88,500 for cars in excellent, high-end condition, and even higher for concours-quality vehicles. 
• Low Value: A project or non-original car could be worth significantly less, potentially in the $20,000$ 20 comma 000$20,000 range.
• Overall: Expect a wide range of prices, from low of $49,995$ 49 comma 995$49,995 to a high of $138,500$ 138 comma 500$138,500 or more, depending on condition and originality.
