continued to decrease the engine's power output, making the smaller version inadequate as increasingly stringent safety regulations also made vehicles heavier. 199 The 199 was produced from 1965 to 1970. Applications: Rambler Classic (1965–66, fleet cars only) Rambler American/AMC Rambler (1965–69) AMC Hornet (1970) AMC Gremlin (1970) VAM Rambler American (mid 1965–1969) U.S. equivalent - AMC Rambler American and AMC Rambler sedans. VAM Camioneta Rambler American (mid 1965–1967) U.S. equivalent - AMC Rambler American wagon. 232 The 232 was produced from 1964 to 1979. The 232 was the base six-cylinder engine on many models through 1979, and even towards the end of its usage was considered reasonably modern in design. After its midyear 1964 introduction in the "Typhoon" two-door hardtop as part of the mid-sized Rambler Classic line, the 232 engine was adapted to fit into the smaller 1965 Rambler American by using a special short water pump, an adaptive piece also used in the 1971–1975 Jeep CJ-5. Air conditioning was available only with the older 196 engine in the American, because there wasn't space for it with the longer 232. Through the 1970 model year, the 232 shared a deck height with the engines. Starting in 1971, AMC raised the deck height to produce the 258, and the 232 adopted the 199's longer connecting rods and shared deck height with the 258. Bore and stroke remained the same. In 1972, the bell housing bolt pattern changed to match the larger version used on the V8 engines. Changes for the 1976 model year included fuel economy improvements that also reduced emissions and reduced warmup time. This was accomplished by reshaped carburetor air passages that pushed the fuel efficiency of a 232-equipped AMC Gremlin to as tested by the United States Environmental Protection Agency, compared to in 1975.
