Ford insiders from the period tell me that the 5. It benefited from a stronger frame and a larger cab introduced in 1973. However, the ram-air shaker was available as an option for 1970. Effective May 2, 1966, 289-2V and 4V engines received important cylinder head and valvetrain changes: rail-style rocker arms, longer valve- stems, revised cylinder head castings, and pent-roof flat-top valvecovers. Markings E, F, G or H as the suffix digit at the end of the part number are also applicable.
Others had a valvecover oil filler neck. . The problem was that racers needed to push it to nearly 9,000 rpm to make checkered-flag power, scattering the engines all over racetracks from coast to coast. The 260 had a true harmonic dampener. Unlike passenger cars, with an average lifespan of about five to seven years, the lifespan of a pickup is considerably longer, at 15 to 20 years. The F-Series trucks debuted in 1948, with the famed F-100s appearing in 1953 with a wider windshield, more room in the cab and a modern look that served as a template for all light-duty pickup truck designs for the next decade. Four engines were offered in the 1978 Ford F-150: the base 114-horsepower, 300-cubic-inch, in-line 6-cylinder, and 460-, 351- and 385-ci V-8s.
Where it becomes challenging is 351W cooling passages between intake manifold and cylinder heads. What engine type is that? C designates a 460-4V Police Interceptor. This indicates the part was originally designed for a 1968 Mercury, and illustrates how parts crossed over from one line to another, across divisions, and the equipment provided on a particular vehicle often determined that different parts were used. The 289 block is a thicker casting designed for larger 4. The 351W was produced exclusively at Windsor.
Some 1964 289 engines were fitted with timing cover oil filler tubes, while most were located in the driver-side valvecover. This 1973 351C-2V is devoid of the ram-air feature with a Motorcraft 2150 carburetor. Mid-Year Changes Important upgrades in the 289 occurred for the 1965 model year beginning in August 1964. It is possible a letter or two may also appear within the series of numerals. Early in the 1970 model year, Ford went to cast-aluminum valve-covers.
Aside from those small differences, the 302 is virtually identical to the 289, including valve size and combustion chamber design. Body Code The first two digits of the three-digit body code is the trim code and identifies the color and type of materials used in the interior upholstery. On top, the Boss 302 had a 780-cfm Holley 4160 4-barrel carburetor. Clean all foreign matter from the yoke areas at the end of the driveshaft s. The additional stroke was chal-lenging to measure at.
The 351 provided 163 horsepower. Early 351W cylinder heads have dog-leg cooling passages, making it necessary to modify intake manifold gaskets and passages. Install all remaining U-joint in the same manner. Get it mixed up and you have unwanted, severe engine-punishing vibration. What can be confusing about these numbers is that a part designed for one year might actually be used for several years, or a part designed for one car line might be used on other lines as well. Photo Courtesy Tim Meyer The 351C is identical to the 351W in terms of bore spacing, size, and bolt patterns.
In fact, the 302 block first showed up in the 1967 model year stuffed full of 289 internals: the 1M crank with 2. All small-blocks originally delivered to a California sales district had closed-crankcase ventilation. Remove the snaprings, which retain the bearings in the flange and in the driveshaft. It had 4-barrel carburetion and the same compression ratio as the 2-barrel available in Mustangs only D engine code. The popularity of the 1970s Ford F-150 lies in the fact that styling did not radically change from model year to model year. In 1978, Ford also began fitting the 302 and other engines with a stamped aluminum air cleaner to reduce vehicle weight. The 351W-2V engine had a more modest compression ratio of 9.
The best pickup truck is probably the Ford F150. The F-150 pickup truck was so rugged and versatile that the frame and overall design was used in 1978 to develop the Ford Bronco line of sport utility vehicles. If it's do F-150s offer a 5. The rest were surplus castings left over from the Tunnel Port days that made it into the Ford Muscle Parts program and dealer pipelines. Beneath this air cleaner is a more emissions-friendly Autolite 2100 carburetor with evaporative emissions and a more aggressive choke pull-off.
