In the history of automotive engines, it is extremely hard to overstate the significance of the V8 design. By splitting up the eight cylinders into two banks of four, designers accomplished an effective, yet compact device which could match the majority of motor bays also size to fit four or six-cylinder engines.

Ford did not create the V8 engine, but it can be relatively stated that they introduced it into everyday use. Some European marques and Cadillac had V8 engines years before Ford developed the motor that could yield affordable performance and make the foundation for hot rodding.

First Generation – 1932-1938

The very first from the Ford L-head (flathead) V8 engines left the factory on March 9, 1932. This engine used a 90-degree obstruct, with all the valves found next to the pistons, directed up-wards. The heads usually are not really flat, getting 4 spade-formed combustion chambers to allow for the motion in the valves. The equipment-driven cam was located in the motor block above the crankshaft and between the cylinder banking institutions, driving solid lifters that acted entirely on the valves. There was two water pumping systems – a single for every tube head.

The piston bore was 3.0625 inches, and also the crank gave a stroke of three.750 inches, to get a complete displacement of 221 cubic in .. Compression with carry heads had been a conservative 5.5:1, which yielded 65 horsepower at 3,400 RPM.

Stock induction in the new flathead V8 was by a single throat downdraft carburetor as well as an aluminium consumption manifold that sat in between the banks of cylinders. A normal carry 65-hp Flathead V8 should yield fuel economic climate at about 20 Miles per gallon.

This motor can be recognized in the field by counting the cylinder head studs, of which there are 21 per side. Later improvements reduced the amount of studs to 17.

The flathead V8 was significantly below improvement in early years, and modifications arrived annually. Earlier 1932 Design 18 motors experienced a reputation for utilizing oil, porous castings, and chilling problems. In 1933, a change to aluminum heads raised the hp rating to 75 for that Model 40. Cooling was also modified and improved.

1934 saw the advent of the two-barrel Stromberg carburetor, increasing productivity to 85 horsepower within the Model 40A. A cast steel crankshaft enhanced dependability. This was the era of the V8 notoriously praised by bank robber Clyde Barrow within a letter to Henry Ford.

For 1935, the Design 38 obtained an up-to-date camshaft. With this point, over 2 million Ford flathead V8 motors had been produced for Ford vehicles and trucks, as well as for industrial utilization in other automobiles. By 1936, the motor was known as a Model 68 and production approved the 3 million tag.

In the 1937 design year, the Ford V8 buyer was provided a selection of aluminium or cast iron heads in the Design 78 motor. The cast iron heads provided a greater compression ratio of 7.5:1 and led to 94 hp compared to 6.2:1 and 85 hp with aluminum heads.

Also in 1937, Ford brought out the smaller 136 cubic inch Model 74 motor, ranked at 60 horsepower and 94 pound-feet of torque. This engine became known as the V8-60, and can be identified by the 17 head studs. This motor became popular in racing as well as for general use since it supplied better fuel economy than the larger motor. 1938 saw continued production of both the V8-85 and also the V8-60.

Second Generation – 1939-1942

For 1939, Mercury additional a brand new version in the Ford flathead V8 design. The newest motor was larger, displacing 239.4 cubic inches by virtue of any longer 3.1875-inch stroke. At a carry compression ratio of 6.3:1, the brand new Design 99A offered 95 hp. V8 production passed the 6 thousand device mark in this calendar year.

Both 239 and 221 cubic ” engines switched to a 24-stud head bolt pattern for 1939, making them aesthetically unique from motors made prior to now. Creation ongoing in 1940 and 1941 with few modifications. Mercury buyers wwmlyd the 239, and Ford customers got the V8-85.

By the starting of 1942, America experienced entered the Second Planet Battle, and incredibly couple of civilian vehicles of any kind had been produced before Ford transitioned all its facilities for the battle work. Needless to say, numerous motors such as V8s had been created through the battle to power various military services vehicles, but additional improvement essentially ceased up until the end in the war.

The period right following the battle had been a growth time for automakers as pent-up demand for new cars was satisfied. Nevertheless, automakers just cranked up manufacture of 1942 styles till new vehicles could be developed. Ford deserted the V8-85, providing all Ford and Mercury vehicles the 239 cubic ” motor, now compressing at 6.8:1 and ranked at 100 hp.
