Like the mechanically similar Malibu, Monte Carlo got only a slightly revised grille to mark this version as an ’83 model. But spring would bring a whole new breed of Monte. As with Malibu, the small 4.4-liter V8 engine option was deleted. Once again, Chevy’s 3.8-liter V6 with 110 horsepower was standard in 49-state cars, while a similar Buick-built engine was used in California. Optional were a 150-horsepower 5.0-liter V8 and a pair of diesels: a 4.3-liter V6 with 85 horsepower and a 5.7-liter V8 with 105 horsepower. Neither diesel proved very popular.
Thundering from the annals of Monte Carlo history came the SS, released in the spring carrying a high-performance 180-horsepower 5.0-liter V8 fitted with a high-lift cam and low-restriction dual exhaust. It boasted a smoother front fascia with integrated bumper and lower lip spoiler, SS badging, a small rear spoiler, and stiffer suspension. Available only in white or dark metallic blue, it was a real “blast from the past,” with spirited acceleration the likes of which had not been seen in a big Chevy for a very long time.
The 5.7 liter diesel V8 must have been the Oldsmobile 350 diesel. Such engines would be weak sellers, due to their mechanical woes.
