History and significance
One of the ultimate big-block American muscle cars, powered by the LS6 454 V8. The body, powertrain and equipment distinguished this version from related mass-produced models.
Its central mechanical specification was 454 cu in (7,4 l) LS6 V8; period output is usually cited as 450 hp SAE brutto. Factory ratings from the era require care when compared with modern SAE net figures.
The commonly quoted production figure is 4 475, covering LS6-equipped 1970 Chevelle-family vehicles, including the El Camino, not just two-door coupes. Original documentation is particularly important when identifying rare variants. The photograph shows the model discussed in this article.
