The carburetor was adjusted in February 2019, and service in November 2019 included checking the fluids and changing the engine oil. Components for the factory air conditioning have been removed, but the bracketry remains. The V8 was rated at 185 horsepower when new and is equipped with a Rochester four-barrel carburetor and a dual-snorkel air-cleaner housing.
