The first Y-block on Ford automobiles and F100 trucks was the 239 cu in (3,910 cc) version as released in 1954 with EBU casting numbers. The Y-block was the same displacement as the old Ford Flathead V8 that it replaced but with a bigger bore and a shorter stroke (3.5 x 3.1 in).
The first-generation Y-block was the 317 cu in (5.2 L), which replaced the undersquare 337 cu in (5.5 L) flathead V8 on all Lincolns in the 1952 model year and was produced through 1954. [2] The 317 was oversquare, as was rapidly becoming the fashion, with a bore of 3.80 in (96.5 mm) and a stroke of 3.5 in (88.9 mm).
1952–1963 Lincoln Y-block V8 engine(317/341/368), HD truck (279/302/317/332) ... In 2018 dual fuel injection added providing both port and direct injection.
Cutaway showing thin-walled, deep-skirted, Y-shaped FE block (ending above the darker colored rectangular oilpan) The FE and FT engines are medium block [citation needed] designs, referred to as Y-block because the cylinder block casting extends below the crankshaft centerline, [citation needed] giving great rigidity and support to the crankshaft's main bearings.
This engine had seven main bearings, and can be identified by the five core plugs on the side of the block. The block uses a low-mount starter and six bellhousing bolts, sharing its bellhousing pattern with the 302 and 351 Windsor V8s, late (1965–68) 289, early 4.6 L V8, and the 240 and 300 inline-six. Production of the 250 ended in 1980.
These engines were used by IHC for some heavy-duty applications until 1935, although their own large engines (525 cu in (8.6 L) FBD and 648 cu in (10.6 L) FEB) had appeared in 1932. [6] The medium-duty 1930 A-series trucks received the all-new 278.7 cu in (4.6 L) FB-3 six-cylinder engine, with overhead valves and seven main bearings.
Note: this is commonly called the Ford Small-block V8 pattern, though it is used in some "big block"-sized V8's as well as some V6's and I6's. 200 I6 1978-1983 only, partial (4 of 6 bolts) pattern. 250 I6 (except Australian 250/4.1) 255 V8; 289 V8 - (made after August 3, 1964) - had 6 bolts holding bellhousing to block; 302 Cleveland (Australia)
The Ford 385 engine family is a series of “big block" overhead valve (OHV) V8 engines designed and manufactured by Ford Motor Company. The family derives its 385 name from the 3.85-inch (98 mm) stroke of the 460 cubic-inch V8 introduced in 1968. [ 3 ]
