The AMC 327 is similar to the [[#287|287]], but displaces {{cvt|327|CID|L|1}} due to the bore increase to {{convert|4|in|mm|1}}. Unlike the 250, most 327s were produced with hydraulic valve lifters. All Gray Marine 327s came with solid lifters, as did the 1957 Rebel. 

The AMC V8 is not related or manufactured by [[Chevrolet]], whose 327 V8 was introduced five years later in 1962.<ref>{{cite book |page=8 |title=Classic Muscle Car Advertising: The Art of Selling Horsepower |first=Mitch |last=Frumkin |publisher=Krause |year=2002 |isbn=978-0-87349-336-9}}</ref><ref>{{cite web |last1=Gillogly |first1=Brandan |title=This 3/27, celebrate Chevrolet's power-packed small-block |url= https://www.hagerty.com/media/automotive-history/celebrate-chevrolets-power-packed-small-block/ |work=Hagerty |date=27 March 2020 |access-date=3 January 2023}}</ref>

The AMC 327 engine debuted in a special edition 1957 [[Rambler Rebel]], of which 1,500 were made. They were an early American [[muscle car]]. All Rebels had silver paint with a gold-anodized "spear" on each side. The 327 was not available in any other Rambler models in 1957. The Rebel's engine differs from the 327s installed in the 1957 Nash Ambassador and Hudson Hornet models in that it uses mechanical valve lifters and a higher compression ratio. Since both engines were rated at {{cvt|255|hp|kW|0}}, it is probable that the Rebel's was underrated.<ref>{{cite web |last=Sealey |first=Mike |title=AMC V8 Engines |website=allpar.com |date=16 November 2020 |url= https://www.allpar.com/threads/amc-v8-engines.229904/#post-1085224002 |access-date=3 January 2023}}</ref>

The Nash Ambassador and Hudson Hornet "Special" models were dropped after 1957, replaced by the 1958 Rambler Rebel with the 250 V8. The Rebel was a V8 version of the Rambler six and included associated upgrades such as stronger front springs and rear axle. The Rebel model name also differentiated it from the standard six-cylinder Rambler. The big Nash and Hudson cars were also dropped after 1957, replaced by the 1958 "Ambassador by Rambler" — a stretched Rebel with the 327 V8 instead of the 250. The 327 was exclusive to the Ambassador line and could not be ordered in a Rebel (or later Classic) through 1964. For 1965 and 1966 the 287 and 327 were both available in the Classic and Ambassador.

The AMC 327 was sold to [[Kaiser-Jeep]] from 1965 until 1967 for use in the [[Jeep Wagoneer]] SUV and Gladiator pick-up truck. Jeep named it the "Vigilante" V8. Two-barrel carburation was standard on these Jeep models, but a four-barrel high-compression version was available in the highly optioned Super Wagoneer from 1966 until 1968. Kaiser-Jeep switched to the [[Buick V8 engine#350|Buick 350]] in 1967 after AMC discontinued the 327. The Buick V8 engine option continued through 1971 after which Jeeps returned to AMC V8 engines, American Motors having purchased Jeep from Kaiser in 1970.

There were low- and high-compression versions of the 327 starting in 1960. Prior to 1960, all 327s were high compression. All low-compression models used a two-barrel carburetor and all high-compression models received a four-barrel carb. The low compression of 8.7:1 and high of 9.7:1 was affected by a difference in pistons.

The AMC 327 was also offered as a marine engine as the "Fireball" by [[Gray Marine Motor Company]].<ref name="books.google.com">{{cite magazine|url= https://books.google.com/books?id=Na0PAAAAIAAJ&q=%22Gray+Marine%22+327+engine |page=15 |title=Gray's new 327-cubic inch Fireball V8 |magazine=The Skipper |volume= 19 |year=1959 |access-date=3 January 2023 |via=Google Books}}</ref>
