Editor's Note: After discovering a photo (seen above) clearly depicting an El Camino and speedboat we don't remember ever seeing, we quickly realized that virtually no one else remembers them either. The researchers at GM's archives were most helpful in tracking down exactly what they were, and in finding more photos. Enjoy.
In 1965, with the muscle car wars in full swing, Chevrolet unveiled its newest weapon in the form of the Mark IV series big block V8. The first salvo was the famed 396 Turbo-Jet, named for its displacement of 396 cubic inches. To highlight its debut, GM made the beauties you see here: the really boss-looking “Surfer I” El Camino roadster and Gaylord ski boat concept.
The Mark IV 396 was never officially used in boating applications, and this was also the first and only appearance of the 396 in an El Camino, making both of these working prototypes purely one of a kind pieces of GM history.
