Available in 200 hp (149 kW; 203 PS) two-barrel carburetor version or producing 225 hp (168 kW; 228 PS) with a four-barrel carburetor and high compression, the new engines utilized "thin-wall" casting technology and weighed only 540 pounds (245 kg). 13 All three engine sizes - 290 cu in (4.8 L 343 cu in (5.6 l and 390 cu in (6.4 L) - share the same basic block design—the different displacements are achieved through various bore and stroke combinations.
Summary of Statement
11 The efi system in the rebel was a far more-advanced setup buddhism than the mechanical types then appearing on the market and the engines ran fine in warm weather, but suffered hard starting in cooler temperatures. 9 All the efi cars were reportedly converted to four-barrel carbs before being sold; none are known to have existed outside the engineering department at amc. The main problem was that early electronics were not fast enough for "on the fly" engine controls. This essay setup was utilised by Chrysler for the 1958 model year on its Dodge, chrysler, Plymouth, and desoto carlines. It too failed, having the same problems. Bendix licensed patents based on their 1950s design (patent dated 1960) to bosch, who perfected it as the basis for their d-jetronic, et seq. Injections system, first used in 1967. Marine application edit The 250 and 327 were also offered as a marine engine known as the "Fireball" by Gray marine motor Company starting in 1958. 7 Gray started offering the 250 in 1959. The 250 was offered in 135, 160, 170, 175, 178 and 185 horsepower versions.
Low-compression.7:1, high.7:1, effected by a difference in pistons. The 327 was also offered as a marine engine as the "Fireball" by Gray marine motor Company. 7 Electronic fuel injection edit The amc 327 was to be the first commercial electronic fuel injected (EFI) "Electrojector" production engine. 8 Press reports about the bendix -developed system in December 1956 were followed in March 1957 by an amc price bulletin offering the efi option on the rambler Rebel for us 395, but due to supplier difficulties, fuel-injected diary Rebels were only available after June. 9 teething problems with the Electrojector unit meant that only a few engineering and press cars were built, estimated to be no more than six units. At least two pre-production Rebels with efi, however, are known to have been built. One was sent to daytona beach, Florida for "Speed week" (the forerunner of today's daytona 500 ). It was the second fastest car on the beach, bested only by a 1957 Chevrolet Corvette with mechanical fuel injection, and only by a couple tenths of a second. 10 The efi 327 was rated at 288 hp (215 kW; 292 PS) and the regular four-barrel carbureted model at 255 hp (190 kW; 259 PS).
The 327, with two barrel carburetor only, was sold to kaiser-jeep from 1965 to 1967 for use in the jeep Wagoneer suv and Gladiator pick-up truck. Jeep named it the "Vigilante". Kaiser-jeep switched to the 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 amc 327 was introduced five years before the Chevrolet 327 engine was manufactured. 5 The amc 327 engine debuted in a special edition 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 ball other than the special edition Rebel. 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 255 hp (190 kW; 259 ps it is probable that the rebel's was underrated. 6 The nash Ambassador and Hudson Hornet "Special" models were dropped after 1957, replaced by the 1958 Rambler Rebel with the 250. The rebel was a rambler with a v-8 (and necessary mods such as stronger front springs and rear axle). The rebel name was added to differentiate the standard six-cylinder Rambler from the v-8 model. 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 19 the 287 and 327 were both available in the Classic and Ambassador.
All 1958-60 V8 Ramblers were called "Rebels" and designated as a different series. It is easy to confuse the 1957 Rambler v-'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 edit Engine bay with amc 287 V8 In mid-model year 1963, amc introduced a 287 cu in (4.7 L). 4 When the 250 was dropped in 1961, there was no V8 option for Rambler models other than the top of the line Ambassador, which was only available with the 327.
Dealers complained, so the 287 was introduced 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. The 287 engine was produced through the 1966 model year. 4 327 edit Engine bay of a 1963 amc ambassador with a 327 V8 four-barrel The amc 327 is similar to the 287, but displaces 327 cu in (5.4 L) due to the bore increase.0 inches (102 mm). Unlike the 250, the 327 was produced with hydraulic valve lifters. Contrary to some myths, the amc v8 was not built by Chevrolet, whose own 327 V8 later became better known.

The oil system feeds a central gallery to the cam and crankshaft first from front to rear, and then dividing at the front to feed the two with lifter galleries from front to rear. From the rear of the two lifter galleries oil is then supplied up to the two rocker arm shafts which serve as galleries to lubricate the valve train. The fore and aft direction changes are designed to eliminate stale oil areas which tend to form sludge deposits. 2 Rebel V8 emblem American Motors' first V8 in-house engine, the 250, was used in American Motors Corporation automobiles from 19It was a modern ohv / pushrod engine design and made its debut in the nash Ambassador and Hudson Hornet "Specials" of 1956. These cars had the top-of-the-line model trim, but were built on the shorter wheelbase (Statesman and Wasp) models (hence the "Special" name citation needed ). The 250 uses solid lifters and came in two- and four-barrel carburetor varieties (4V only in Nash/Hudson "Specials. The 250 V8 was optional in the 1957 Rambler.

See also 1, all these engines share common external dimensions, light weight - about 600 lb (270 kg) - forged crankshaft and rods, as well as most other parts. 4, the stroke for all Gen-1 V8s.25 inches (82.6 millimetres). Engine displacement was a factor of the bore: the 250 cu in (4.1 L) has.5-inch (88.9 mm) bore, 287 cu in (4.7 L).75 in (95.3 mm and the 327 cu in (5.4 L).0 in (101.6 mm) bore. The bore size is cast on the top of the block near the back of the right bank cylinder head. The block features a deep skirt where the casting extends below the crankshaft centerline, forming a very for rigid crankcase gallery.
engineering department hired david Potter, a former. Kaiser Motors engineer, to help develop the engine. Potter had previously worked on a v8 design for kaiser, and they were able to get the all new V8 into production in less than 18 months. Citation needed, the 1956 sae article named "The new American Motors V8" opens with direct acknowledgement to dave potter and John Adamson as the authors. The article concludes by giving credits to the engine's actual designers saying; "The entire program was under the direction of meade. Moore, vice President of Automotive research and Engineering, and through his efforts the project was carried on cooperatively by our Kenosha and Detroit Engineering Departments. Obviously, such a division in both design and development, required the utmost in teamwork. Kishline, chief Engineer, and his assistants,.
2, the quaint sounding traditional tale of how amc's first V8 engine came into being is as follows; American Motors' president, george. Mason, negotiated a verbal agreement with. Packard that the two companies would supply parts for each other when practical. This was a prelude to a possible merger of the two companies at a later date, but that never occurred. With the industry-wide acceptance of V8 engine designs after. World War ii, amc started buying Packard V8s in 19Nash Ambassador and, hudson thesis Hornet. These were supplied with Packard ". Ultramatic " automatic transmissions - exclusively. Packard sent amc some parts bids, but these were rejected as too expensive.

Despite packaging labels shown by aftermarket parts makers, am's first V8 engine only served Nash and Hudson nameplates for two years. The presentation engine was traditionally called 'rambler V8' because it powered those 'rambler division' cars amc made during the American Manufacturer Association ban on factory supported racing from 1957 to 1962, whereas the former racing goals of Nash and Hudson motorcars were ended and those two. The ama ban was a direct result of the '55 lemans Disaster and the '57 nascar crash into the grandstands.
