The 396 (6.5 L) engine is added to the options sheet for the 1966 model year. The new engine allows the El Camino to turn in consistent mid to low 14 second tines in the quarter mile. This year the El Camino line shares its sheet metal with the Chevelle as well as offering similar trim options. The bare bones El Camino is similar to the Chevelle 300 entry level line-up and equipped with a bench seat with vinyl floor covering, but the Custom version is outfitted like the Malibu, with uptown cloth/vinyl interior with a carpeted floor and could also include the strato swivel bucket seats plus a console.
We love both of them!!
