    • 1982–1985 Single-source

      Ciera years: Wikipedia's Ciera engine table and its Oldsmobile Diesel article (LT7 section lists the Ciera 1982–1985); the diesel was dropped in spring 1985; shared A-body code; cited from the Chevrolet Celebrity kits (the 1984 page's year field reads garbled, so 1984 rests on Wikipedia)
