The Autolite 4300 was a Ford (also used by AMC) carburetor manufactured from 1967 through 1974. These carburetors were produced as an emissions-compliant replacement for the previous Autolite 4100 model, and were later superseded by the Motorcraft 4350.
Both the 4300A and 4300D are unique by virtue of having spread bore throttle plate designs (the 4300A being much less pronounced than the 4300D) that are unique to these carburetors and their relative intake manifolds.
The first version of this carburetor was released in 1967, replacing the 4100 on all Fords excluding the police package 428 CID and 289 CID high-output engines. [1]
4300A 441 CFM specs: [2]
The 441 CFM carburetor was found to run too lean for the 390 CID engines; hence, the 600 CFM 4300A was developed the following year for these larger applications. [3] The 441 CFM 4300A was discontinued after the 1969 model year in favor of the two-barrel Autolite 2100 carburetor. [3]
Due to the limited flow of the 441 CFM version of the 4300A, a 600 CFM version of the same was released in 1968. [1] By 1970, it was factory supplied on most Fords equipped with the 429 and 460, in addition to vehicles with the 351 Cleveland. [3]
4300A 600 CFM specs: [2]
In 1971, a much more pronounced spreadbore design was released, dubbed the 4300D. They are incompatible with other spreadbore intake designs. [1]
4300D 715 CFM specs: [2]
The 4300D was replaced by the Motorcraft 4350 carburetor in 1975. [1]
Both variants of the 4300 have been criticized for poor acceleration, rough operation, and a potential for fire due to a poor fuel inlet design. [3] [4] This negative reputation is not universally accepted amongst users of these carburetors.
A carburetor or carburettor is a device that mixes air and fuel for internal combustion engines in an appropriate air–fuel ratio for combustion. The term is sometimes colloquially shortened to carb in the UK and North America or to carby in Australia. To carburate or carburete means to mix the air and fuel or to equip with a carburetor for that purpose.
The Ford FE engine is a Ford V8 engine used in vehicles sold in the North American market between 1958 and 1976. The FE was introduced to replace the short-lived Ford Y-block engine, which American cars and trucks were outgrowing. It was designed with room to be significantly expanded, and manufactured both as a top-oiler and side-oiler, and in displacements between 332 cu in (5.4 L) and 428 cu in (7.0 L).
The Ford 385 engine family is a series of big block V8 engines designed by Ford Motor Company. Produced from 1968 to 1998, the Lima engines replaced the MEL engine entirely, along with multiple engines of the medium-block FE engine family; in truck applications, the engines succeeded the much larger Super Duty family.
The CVH engine was introduced by Ford in 1980 in the third generation European Ford Escort and for the 1981 North American Escort. It was later used in the Ford Sierra as well as the second generation Ford Fiesta and from 1983 it was used in the Ford Orion. Engines were built in the Dearborn Engine Plant for the North American market, and in Ford's then-new engine plant in Bridgend in Wales for the European market.
The Ford 335 engine family was a group of engines built by the Ford Motor Company between 1969 and 1982. The "335" designation reflected Ford management's decision to produce an engine of that size with room for expansion during its development. This engine family began production in late 1969 with a 351 cu in (5.8 L) engine, commonly called the 351C. It later expanded to include a 400 cu in (6.6 L) engine which used a taller version of the engine block, commonly referred to as a tall deck engine block, a 351 cu in (5.8 L) tall deck variant, called the 351M, and a 302 cu in (4.9 L) engine which was exclusive to Australia.
The Ford Boss 302 is a high-performance "small block" 302 cu in (4.9 L) V8 engine manufactured by Ford Motor Company. The original version of this engine was used in the 1969 and 1970 Boss 302 Mustangs and Cougar Eliminators and was constructed by attaching heads designed for the planned 351 Cleveland to a Ford small block. The construction was aided by the two engines sharing a cylinder head bolt pattern, though the Boss heads had to have their coolant passages slightly modified.
The Ford small block is a series of 90° overhead valve small block V8 automobile engines built by the Ford Motor Company from July 1961 to 2002.
The Y-block engine is a family of overhead valve V8 automobile engines produced by Ford Motor Company. The engine is well known and named for its deep skirting, which causes the engine block to resemble a Y. It was introduced in 1954 as a more modern replacement for the outdated side-valved Ford Flathead V8 and was used in a variety of Ford vehicles through 1964.
The Ford Pinto engine was the unofficial but generic nickname for a four-cylinder internal combustion engine built by Ford Europe. In Ford sales literature, it was referred to as the EAO or OHC engine and because it was designed to the metric system, it was sometimes called the "metric engine". The internal Ford codename for the unit was the T88-series engine. European Ford service literature refers to it as the Taunus In-Line engine. In North America it was known as the Lima In-Line (LL), or simply the Lima engine due to it being manufactured at Lima Engine in Lima, Ohio.
The Essex V6 is a 90° V6 engine family built by Ford Motor Company at the Essex Engine Plant in Windsor, Ontario, Canada. This engine is unrelated to Ford's British Essex V6. Introduced in 1982, versions of the Essex V6 engine family were used in subcompact through to large cars, vans, minivans, and some pickup trucks. The Essex V6 was last used in the 2008 regular-cab F-150, after which it was succeeded by a version of the Ford Cyclone engine. An industrial version of the engine was available until 2015.
In 1906–1907, Ford's first straight-six engine was introduced in the Model K. Henry Ford did not like the car because the engine could overpower its transmission.
In automotive engineering, an inlet manifold or intake manifold is the part of an engine that supplies the fuel/air mixture to the cylinders. The word manifold comes from the Old English word manigfeald and refers to the multiplying of one (pipe) into many.
The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time.
The Ford Mustang Mach 1 is a performance-oriented option package of the Ford Mustang, originally introduced in August 1968 for the 1969 model year. It was available until 1978, returned briefly in 2003, 2004, and most recently 2021.
A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.
The Quadrajet is a four barrel carburetor, made by the Rochester Products Division of General Motors. Its first application was the new-for-1965 Chevy 396ci engine. Its last application was on the 1990 Oldsmobile 307 V8 engine, which was last used in the Cadillac Brougham and full size station wagons made by Chevrolet, Pontiac, Oldsmobile, and Buick.
The LaserJet 4000 series is Hewlett-Packard's medium-duty monochrome laser printer range and the successor to the LaserJet 5 series.
The first-generation Ford Mustang was manufactured by Ford from March 1964 until 1973. The introduction of the Mustang created a new class of automobile known as the pony car. The Mustang’s styling, with its long hood and short deck, proved wildly popular and inspired a host of competition.
Of the three types of carburetors used on large, high-performance aircraft engines manufactured in the United States during World War II, the Bendix-Stromberg pressure carburetor was the one most commonly found. The other two carburetor types were manufactured by Chandler Groves and Chandler Evans Control Systems (CECO). Both of these types of carburetors had a relatively large number of internal parts, and in the case of the Holley Carburetor, there were complications in its "variable venturi" design.
The Motorcraft 2150 is a Ford 2-barrel carburetor manufactured from 1973 through 1983, based heavily on its predecessor, the Autolite 2100 carburetor.
