to confuse the 1957 Rambler V8 and the 1958-'60 Rebel line with the special 1957 Rambler Rebel, a limited edition muscle car (see 327 below). In 1961, The Rambler Six was renamed the "Rambler Classic" to avoid model confusion in the Rambler line-up. A V8 engine then became an option in the Classic instead of a separate model. 287 When the 250 was discontinued in 1961. A V8 engine was not offered in the Rambler models with the exception of the 327, which was only available in the top-of-the-line Ambassador. Dealers complained, so the V8. was introduced in mid-model year 1963 as an option for the "mid-size" Rambler. Like the 327, it uses hydraulic valve lifters. Only two-barrel models were produced, there were no four-barrel options from the factory for the 287 as this was the economy model V8. The 287 engine was produced through the 1966 model year. 327 The AMC 327 is similar to the 287, but displaces due to the bore increase to .

The AMC V8 is not related or manufactured by Chevrolet, whose 327 V8 was introduced five years later in 1962. 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 , it is probable that the Rebel's was underrated. 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 the appropriate 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.
