In the history of automotive engines, it is extremely hard to overstate the importance of the V8 design. By dividing the 8 cylinders into two banks of four, engineers achieved a strong, yet compact unit that could match the majority of engine bays also size to fit four or 6-cylinder engines.

Ford did not create the V8 motor, however it can be fairly claimed that they introduced it into daily use. Some European marques and Cadillac experienced V8 engines years before Ford developed the motor that would yield inexpensive performance and make the basis for hot rodding.

First Era – 1932-1938

The first from the Ford L-head (flathead) V8 engines left the factory on March 9, 1932. This engine used a 90-degree obstruct, using the valves found next to the pistons, pointed up-wards. The heads are not really flat, getting 4 spade-shaped combustion compartments to support the motion from the valves. The equipment-powered cam was based in the engine obstruct higher than the crankshaft and in between the cylinder banks, driving solid lifters that behaved right on the valves. There have been two drinking water pumps – a single for each tube head.

The piston bore was 3.0625 inches, and also the crank provided a cerebrovascular event of 3.750 inches, to get a total displacement of 221 cubic in .. Compression with carry heads had been a conservative 5.5:1, which yielded 65 hp at 3,400 RPM.

Stock induction on the new flathead V8 was by a single tonsils downdraft carburetor and an aluminum intake manifold that sat between the banks of cylinders. A normal carry 65-hp Flathead V8 ought to produce energy economic climate at about 20 Miles per gallon.

This motor can be identified within the field by keeping track of the tube head studs, which you can find 21 for each part. Later on improvements decreased the number of studs to 17.

The flathead V8 was greatly below development during the early many years, and modifications arrived yearly. Earlier 1932 Design 18 engines enjoyed a track record of using oil, permeable castings, and cooling issues. In 1933, a change to aluminium heads elevated the horsepower rating to 75 for the Model 40. Cooling was also modified and improved.

1934 saw the advent of a two-barrel Stromberg carburetor, increasing output to 85 hp in the Model 40A. A cast steel crankshaft enhanced dependability. This was the generation in the V8 famously recognized by bank robber Clyde Barrow inside a letter to Henry Ford.

For 1935, the Design 38 obtained an updated camshaft. From this point, over 2 thousand Ford flathead V8 engines had been created for Ford vehicles and trucks, and for industrial use in other vehicles. By 1936, the motor was known as a Design 68 and creation passed the 3 thousand mark.

Within the 1937 design year, the Ford V8 purchaser was offered a selection of aluminum or cast iron heads around the Model 78 motor. The cast iron heads offered a greater compression ratio of 7.5:1 and resulted in 94 hp when compared with 6.2:1 and 85 horsepower with aluminum heads.

Also in 1937, Ford introduced the smaller 136 cubic inch Model 74 motor, ranked at 60 hp and 94 pound-feet of torque. This engine grew to become known as the V8-60, and can be identified by the 17 head studs. This engine grew to become well-known in racing as well as for general use because it provided much better energy economy than the bigger motor. 1938 saw ongoing production of both the V8-85 and the V8-60.

Second Era – 1939-1942

For 1939, Mercury added a new version from the Ford flathead V8 design. The new engine was larger, displacing 239.4 cubic in . by virtue of the for a longer time 3.1875-inch cerebrovascular event. At a carry pressure ratio of 6.3:1, the brand new Design 99A offered 95 horsepower. V8 production approved the 6 million unit tag in this calendar year.

The 239 and 221 cubic ” motors switched to a 24-stud head bolt design for 1939, causing them to be aesthetically unique from engines created before now. Creation ongoing in 1940 and 1941 with couple of modifications. Mercury customers wwmlyd the 239, and Ford buyers received the V8-85.

By the beginning of 1942, America had entered the Second World Battle, and very couple of civilian vehicles for any kind were created before Ford transitioned all of its facilities to the war work. Needless to say, numerous engines including V8s were produced throughout the battle to energy different military vehicles, but further improvement essentially ceased up until the finish from the battle.

The period right right after the war was a boom time for automakers as pent-up interest in new vehicles was satisfied. However, automakers just cranked up production of 1942 designs till new cars might be developed. Ford abandoned the V8-85, providing all Ford and Mercury vehicles the 239 cubic inch engine, now compressing at 6.8:1 and rated at 100 horsepower.
