• The 1973 Dodge Monaco was one of the last behemoth Dodges on the road before the 1973 and 1978 oil crises conspired to consign gas-guzzlers to the dustbin of automotive history. The Monaco belonged to Dodge luxury line of cars and the Monaco Brougham was the top trim level package. The 1973 model was part of the 1965 to 1978 and 1990 to 1992 Monacos. Model year 1973 sales were poor with 29,396 Monacos sold.

• The 1973 Dodge Monaco Brougham's base engine was the 175-horsepower 360-cubic-inch V8 wielding 285 ft.-lbs. of torque. It featured an 8.7:1 compression ratio, 2-barrel carburetor and a 4-inch bore and a 3.58-inch stroke. It's the same engine that later powered the mid-size Dodge Dakota pickups and Dodge Durango and Jeep Grand Cherokee sport utility vehicles. Buyers in 1973 could order the optional 400 with a 4.34-inch bore and 3.38-inch stroke, 8.2:1 compression ratio and two-barrel carb to generate 190 horsepower and 310 ft-.lbs. of torque. The biggest engine option was the 440 with a 4.32-inch bore and 3.75-inch stroke and 8.2:1 compression ratio to provide 225 horsepower and 345 ft.-lbs. of torque. Transmissions available to complement the engines were the three-speed manual and optional three-speed TorqueFlite automatic. It wasn't until 1974 that the Dodge Monacos gained widespread use as police patrol cars, so no performance Police Interceptor engines were available in 1973.
