Chevrolet El Camino
1976 Chevrolet El Camino: For 1976, El Camino Classic models now featured the new rectangular headlights that other high-end GM cars were sporting. These were quad units in stacked arrangement. The base model retained the previously used dual round headlights. Engines included the base 250 I6 engine, a new 140-horsepower 305-cubic-inch V8, two- and four-barrel 350s (with availability still depending on California delivery), and the 400-cubic-inch V8, still good for 175 hp. All engines except the 250 I6 came with the Turbo Hydra-matic automatic transmission as the only transmission available. The 250 I6 came with a 3-speed manual or an optional Turbo Hydra-matic.
The 1977 models were little changed, except the 400 V8 was gone. The El Camino Classic was again the top model and the SS option continued.
