Chevrolet Monte Carlo Landau
A revised grille with the Monte Carlo "Knight's Crest" emblem moved to a stand-up hood ornament and revised taillight lenses marked the 1977 Monte Carlo, which was the last year for the 1973-vintage design before the introduction of a downsized 1978 Monte Carlo. Engine offerings were reduced to two engines for 1977. The base engine for 49 states was the 140 hp (100 kW) 305 CID 2-barrel V8 and the 170 hp (130 kW) 350 4-barrel V8 was optional (standard in California). The 400-cubic-inch V8 was dropped as an engine option. The Turbo Hydra-matic transmission was included standard equipment.
Interior trim received only minor revisions this year with upholstery choices including cloth, velour and vinyl in both base and Custom trims.
This model year marks the only time in history when an intermediate model was larger in every dimension than a full-sized model, as the B-body Chevrolet Caprice/Impala had already been redesigned and downsized for 1977.
