Chronology
Predecessor Flathead V8
Successor Ford MEL V8
Ford Super Duty engine

The Lincoln Y-block V8 engine was Ford's earliest OHV V8 engine, introduced by Lincoln in the 1952 model year. [2] Like the later and better-known but even more short-lived Ford Y-block engine, its block's deep skirts gave the block the appearance of the letter Y from the front. [3]

Contents

The Y-block's development was in response to the sales success of the competing Oldsmobile "Rocket" and Cadillac OHV V8 engines, introduced in the 1949 model year, the Buick "Nailhead" engine introduced in the 1953 model year, and the OHV V8 Chrysler Hemi engine in 1951. Also, Ford needed larger and more powerful truck engines. The basic engine design was produced through 1963. [4] It was replaced by the newer MEL engine for car applications in 1958, [2] and was replaced in heavy-duty truck applications by the FT (330/361/391) engines starting in 1964.

279

A 279 cu in (4.6 L) version of the Lincoln Y-block was produced for heavy-duty truck applications for the 1952 through 1955 model years. [4] The engine had a bore of 3.5625 in (90.5 mm) and a stroke of 3.5 in (88.9 mm). [4] [5] [6]

302

The 302 cu in (4.9 L) version of the Lincoln Y-block was used for heavy-duty truck applications from the 1956 through the 1963 model year. [4] The engine had a bore of 3.625 in (92.1 mm) and a stroke of 3.65625 in (92.9 mm). [4] [5] [6] Power output was 196 hp (146 kW). [7] The engine was optional equipment on the Ford T-700 Series and standard equipment on the Ford F-750, C-750, and B-750 Series heavy-duty trucks. [7]

317

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). [3] [4] [5] [6] Power output with a two-barrel carburetor was 160 hp (119 kW). higher compression, larger intake valves, a Holley four-barrel, improved intake and exhaust, and a more aggressive camshaft, the next year increased it all the way to 205 hp (153 kW). [3] The engine was unchanged in 1954 except for the vacuum advance mechanism. [3] These engines used hydraulic valve lifters while Ford truck engines used solid. The stock Lincoln 317 powered the "Mexican Road Race Lincolns". The 317 was replaced by the 341 for automobile applications in the 1955 model year. [2] Like the 279, the 317 was also used in heavy-duty truck applications for the 1952-55 model years . [4]

Lincolns powered by the 317 won the top four spots in the Stock Car category of the Pan American Road Race in both 1952 and 1953. [2] In 1954 Lincolns took first and second place. [2]

332

The 332 cu in (5.4 L) version of the Lincoln Y-block was used for heavy-duty truck applications from the 1956 through the 1963 model year. [4] The engine had a bore of 3.80 in (96.5 mm) and a stroke of 3.65625 in (92.9 mm) [4] [5] [6] and produced 212 hp (158 kW). [7] The engine was standard equipment on the Ford F-800, F-900, T-750, T-800, C-800, and C-900 Series heavy-duty trucks. [7]

341

The 317 cu in (5.2 L) automobile engine was bored out in 1955 to 3.94 in (100.1 mm), displacing 341 cu in (5.6 L). [3] [4] [5] [6] Power was up to 225 hp (168 kW) and torque 450 N⋅m (332 lb⋅ft). [3] in its sole year of production. [2]

368

In the 1956 model year the 341's bore was increased to 4 in (101.6 mm) and stroke to 3.65625 in (92.9 mm) to create a 368 cu in (6.0 L) engine [3] [4] [5] [6] that produced 285 hp (213 kW) and 545 N⋅m (402 lb⋅ft). [3] In 1957 horsepower increased to 300 hp (224 kW) with 563 N⋅m (415 lb⋅ft) of torque but the Lincoln still lagged in horsepower and torque behind the Chrysler Hemi 392 used on the Imperial, Chrysler New Yorker, and 300C, and in horsepower behind the 3-2bbl version of the Cadillac 365 used on the Eldorado. [3] The 368 was standard equipment on all Lincolns in the 1956 and 1957 model years, [2] and standard on the Mercury Turnpike Cruiser and Colony Park and optional on the Mercury Montclair, Monterey, Voyager, and Commuter [2] in 1957, its final year.[ clarification needed ]

<span class="mw-page-title-main">Ford flathead V8 engine</span> Reciprocating internal combustion engine

The Ford flathead V8 is a V8 engine with a flat cylinder head designed by the Ford Motor Company and built by Ford and various licensees. During the engine's first decade of production, when overhead-valve engines were used by only a small minority of makes, it was usually known simply as the Ford V‑8, and the first car model in which it was installed, the Model 18, was often called simply the "Ford V-8", after its new engine. Although the V8 configuration was not new when the Ford V8 was introduced in 1932, the latter was a market first in the respect that it made an 8-cylinder affordable and a V engine affordable to the emerging mass market consumer for the first time. It was the first independently designed and built V8 engine produced by Ford for mass production, and it ranks as one of the company's most important developments. A fascination with ever-more-powerful engines was perhaps the most salient aspect of the American car and truck market for a half century, from 1923 until 1973. The engine was intended to be used for big passenger cars and trucks; it was installed in such until 1953, making the engine's 21-year production run for the U.S. consumer market longer than the 19-year run of the Ford Model T engine for that market. The engine was on Ward's list of the 10 best engines of the 20th century. It was a staple of hot rodders in the 1950s, and it remains famous in the classic car hobbies even today, despite the huge variety of other popular V8s that followed.

The Ford Motor Company produced straight-six engines from 1906 until 1908 and from 1941 until 2016. In 1906, the first Ford straight-six was introduced in the Model K. The next was introduced in the 1941 Ford. Ford continued producing straight-six engines for use in its North American vehicles until 1996, when they were discontinued in favor of more compact V6 designs.

Ford developed the MEL ("Mercury-Edsel-Lincoln") engine series as the replacement for the Lincoln Y-block V8 engine for use in large passenger car applications. These engines were produced in Lima, Ohio at Ford's Lima Engine plant. They were in turn replaced by the 385 series engines.
