Chevrolet introduced a longer third generation El Camino in 1968, based on the Chevelle station wagon/four-door sedan wheelbase (116 in (2,946 mm), overall length: 208 in (5,283 mm)); it also shared Chevelle Malibu exterior and interior trims. A new, high-performance Super Sport SS396 version was launched. The Turbo-Jet 396 was offered in 325 bhp (242 kW) or 350 bhp (260 kW) versions. Returning to the official options list for the first time since late 1966 was the 375 bhp (280 kW) L78. It had solid lifters, big-port heads, and an 800 cfm Holley four-barrel on a low-rise aluminum manifold. A three-speed manual was standard with all engines, and a four-speed or automatic was optional. The third generation of El Camino was built until 1972, when it was replaced by the Fourth Generation Chevrolet El Camino.
