Cylinder Heads Casting numbers for cylinder heads may change from year to year. Only things that matter with late blocks are whether block has zero, eight, or 15 hardened seats ease the rebuild greatly! Stationary engines were normally truck type lower compression too. The longer stroke Mercury has a dimple as you can see in the picture below. Any casting number used on 312 blocks was also used on 292 blocks. The easiest way to determine if the Canadian made engine you have is a Mercury is to look at the crankshaft front counterweight. Flywheels and bell-housings are interchangeable along with timing covers and crankshaft dampers. Re: mercury tower of power 6 cyl.
Dearborn 272 Block Cleveland 292 or 312 Block 312 flange dot Regardless of the source, the external dimensions of all Ford Y-Blocks are the same. The serial number is the top number on the plate. Many newer Mercury outboards have the model year stated prominently on this sticker. On 8-cylinder engines, it is where the starter bolts onto the bell housing and the starter may have to be removed to locate it. If not, locate the product identification plate on the engine mounting bracket.
Hence, a late model 289 coming from the Cleveland plant might have a 302 block with 289 innards. After so many years, it would be somewhat unusual for a block to be in its original vehicle or its original cylinder heads. This is due to the fact that the same 100hp 239 cubic inch engine was used in Fords and in Mercurys. I'll leave it up to you to research it, and then when you have the answer, let me know too. From 1955 until the end of production in 1964, parts can be easily interchanged.
The easiest way to discern if a part is a factory original or service replacement part is to check the fourth digit of the part number. The Windsor plant had an abundance of 289 blocks for 1967. Both are wheel assemblies, but they have very different applications. Model Number and Serial Number These numbers are located on the transom bracket of the motor. Complete Engines, Lower Units and Sterndrives excluded. They all came off the machining line with the same bores, valve seat diameters, main bearing bores, and cam bores barring production errors.
Y-Blocks were also used for industrial power plants and converted for marine use by Dearborn Marine. Identify Your Y-Block Identifying Your Y-Block The Ford Y-Block was introduced in 1954. On the tag is the displacement, assembly plant, model year, change level, engine code useful in identifying high performance engines and date of production. According to the parts book, this switch fits a 1968 Ford Thunderbird with tilt steering wheel. The dealer is the gold standard for information about your Mercury outboard and, using Mercury's proprietary resources, can provide you with the outboard's model year.
The unique identifier is a series of numbers and letters that are put in a specific sequence, and the location of the digit determines what that digit designates. In 1969 Cleveland continued with 302 production. In 1968 Cleveland only made 302s, while Windsor continued with the 289s. There were no special truck blocks. The frame numbers which match the engine transmission number is usually stamped in three places on the top surface of the left-hand frame rail front, center and rear.
If the engine is still in the vehicle, you will need to remove the transmission cover from the inside to see the code. Find the engine serial number on 1949 to 1954 Flatheads. Block identification number generally on side of block above oil filter for blocks cast at Cleveland. The Ford part number on the box shown at left is on the top line: B8A-9431-A. The sequence continued to the end of production in 1948, the only changes being in the 1947 prefix 799A and in the 1948 prefix 899A. The numbers are not indented in the block. In 1939, some engines were sleeved thin sheetmetal sleeve allowing instant engine rebuild with a simple puller kit and others had plain bores.
I think it is from a vehicle sold in an area requiring serial to be stamped on motor. V8 1958-1959 cars and trucks to April '59. In mid-year 1966 the Windsor plant also began producing 289s. This might be also of some interest per Scatty also a member here. Markings E, F, G or H as the suffix digit at the end of the part number are also applicable. Parts finished in different colors can be identified by their suffix numbers as well.
These numbers provide a lot of information to those who are familiar with what the numbers mean. This engine was used on all Mercuries, and option on big trucks, and also apparently used on special order mostly police Fords. Any year exhaust manifold will bolt to any year head. Check out this page too: 071103. This engine can easily be identified by the location of the distributor, which is at the rear, on top of the block, next to the fuel pump and by the external water bypass tubes. The reverse situation could also occur.
Ford placed a tag under the coil-attaching bolt which contains all the necessary information to positively identify the engine, but it is easily lost or replaced with a fake tag. The difference between the Ford and Mercury engines is not apparent from the outside. Identification of Mercury Flatheads requires locating the engine code, which determines the date of manufacture. Enter the engine's serial number in the block provided and you get the engine's model year and a comprehensive parts list. Although all Y-Blocks use the same connecting rod bearing with 2. First, locate the horsepower of your outboard on the chart, then look down the list of serial number ranges. The difference between a Ford and a Mercury engine.
