About the Ford V8 Flathead.
The Ford flathead V8 (often called simply the Ford flathead or flathead Ford when the V8 context is implicit, such as in hot-rodding) was a V8 engine of the flathead type, 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 rare, it was usually known simply as the Ford V-8, and the first car model in which it was installed, the Model 18, was (and still is) often called simply the "Ford V-8", after its new engine. When the engine was introduced in 1932, it was a market first in several respects: in cars that were affordable to the emerging mass market consumer, it was the first 8-cylinder, the first V8, and the first V engine to become available. 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 Ford flathead V8 was perfectly in tune with the cultural moment of its introduction, leading the way into a future of which the Ford company was a principal architect. Thus it became a phenomenal success. The engine design, with various changes but no major ones, was installed in Ford passenger cars and trucks 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.
Ford also designed and produced a smaller 60hp flathead V8 engine from 1937 until 1940. Lastly, the big 337 cubic inch flathead V8 engine, which was produced mainly for truck use and for Lincoln cars from 1948 to 1951. Ford's flathead V8 engines when introduced in 1932 were the first mass-production V8's where the block and cylinder assembly were poured as one single casting.
One of the most important innovations in the Ford flathead V8 was the casting of the crankcase and all 8 cylinders in one engine block. This was the first time a V8 had ever had that particular level of monobloc design, which was an example of the production development needed to bring a V8 engine to the widely affordable segment of the market. Most V engines of the time had multiple cylinder blocks bolted to a common crankcase (itself a separate casting). At most, each bank of the V was an integral block, but many V engines had 4- or even 6-cylinder blocks, with cylinders cast in pairs or triples. Like most other engine blocks then and now, it was cast iron; but the foundry practice (e.g., workflows, materials handling) was a revolutionary advancement in the mass production of castings. Charles E. Sorensen lived up to his longtime nickname at Ford, "Cast-Iron Charlie", by leading this revolution to bring Ford's first V8 to market.
