Editing AMC straight-6 engine (section)

===232===
The {{cvt|232|CID|L|1}} engine was produced from 1964 until 1979. The 232 was the base six-cylinder engine on many models through 1979, and even towards the end of its usage, it was considered reasonably modern in design.<ref>{{cite book |title=Chilton's Auto Repair Manual 1982 |year=1987 |publisher=Chilton |isbn=978-0-8019-7052-8}}</ref>

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 through 1975 Jeep CJ-5.<ref name="amcyclopedianode16">{{cite web |url= http://www.amcyclopedia.org/node/16 |title=1964 — 1965 American |author=((mhaas)) |date=17 January 2006 |website=amcyclopedia.org |archive-url= https://web.archive.org/web/20140302073556/http://www.amcyclopedia.org/node/16 |archive-date=2 March 2014 |access-date=17 April 2024}}</ref> Air conditioning was available only with the older 196 engine in the American models because there was not enough space for the compressor with the longer 232.<ref name="amcyclopedianode16"/>

Through the 1970 model year, the 232 shared a deck height with the {{cvt|199|CID|L|1}} 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.<ref name="amcyclopedianode16"/>

Changes for the 1976 model year included [[Fuel economy in automobiles|fuel economy]] improvements that reduced emissions and warmup time.<ref name="ps75-10">{{cite magazine|last=Dunne |first=Jim |title=How American Motors does it |magazine=Popular Science |date=October 1975 |volume=207 |issue=4 |url= https://books.google.com/books?id=LQEAAAAAMBAJ&q=AMC+232+six&pg=PA117 |page=117 |via=Google Books |access-date=17 April 2024}}</ref> This was accomplished by reshaped [[carburetor]] air passages that pushed the [[fuel efficiency]] of a 232-equipped [[AMC Gremlin]] to {{cvt|30|mpgus|L/100 km mpgimp}} as tested by the [[United States Environmental Protection Agency]], compared to {{cvt|24|mpgus|L/100 km mpgimp}} in 1975.<ref name="ps75-10"/>
