Chevrolet Chevelle and Chevelle SS history
By CarWhere Research · Updated
The Chevrolet Chevelle was Chevrolet's midsize car for the 1964 to 1977 model years, across three generations: 1964–1967, 1968–1972 and 1973–1977. The Chevelle SS became a muscle-car icon through the 1965 Z16, the SS 396 series from 1966 and the 1970 SS 454 LS6, rated at 450 hp. Malibu replaced the name for 1978.
Chevrolet Chevelle history
Chevrolet launched the Chevelle for 1964 as a midsize car slotted between the compact Chevy II and the full-size Impala, and the El Camino returned that year as part of the Chevelle line. The first model year was a hit, with 294,160 Chevelles built, including 76,860 with Super Sport equipment.
The performance story began with the 1965 Z16, which put the new 396 cu in big-block into a Chevelle; only 200 regular-production Z16s were built at the Kansas City plant. The SS 396 became its own series for 1966, and a restyled second generation followed for 1968.
The 1970 SS 454 was the peak: the LS5 454 was rated at 360 hp and the LS6 at 450 hp gross and 500 lb-ft, and 4,475 LS6 Chevelles were built that year. A larger third generation arrived for 1973, and after 1977 Chevrolet dropped the Chevelle name in favor of Malibu.[1]

What to check before you buy one
- Treat SS, Z16 and LS6 claims as unproven until the car's original documentation and casting/stamping numbers have been checked by a specialist — clones are common.
- Inspect the frame, rear window channel, trunk floor and lower quarters for rust and repair quality.
- Ask whether the engine is original to the car ("numbers matching") or a replacement, since that changes value significantly.
- Get the restoration history, receipts and photos, and have a marque specialist inspect the car before purchase.
How to verify a Chevrolet Chevelle's factory options
Every Chevelle predates standardized 17-character VINs, which began with the 1981 model year.[2]
For cars built before the 17-character VIN, identification rests on the car's own serial number, its body and trim tags, engine stampings and its documented history. The GM Heritage Center maintains General Motors' historical archive and publishes vehicle information kits for many past GM models.[3]
