In the history of automotive engines, it’s extremely hard to overstate the significance of the V8 design. By dividing the 8 cylinders into two banks of 4, designers achieved a strong, yet compact unit that could match the majority of engine bays also size to fit 4 or 6-cylinder engines.

Ford failed to invent the V8 motor, however it can be relatively said that they introduced it into daily use. Some Western marques and Cadillac had V8 engines years before Ford developed the engine that could produce inexpensive performance and produce the cornerstone for hot rodding.

Initially Generation – 1932-1938

The initial of the Ford L-head (flathead) V8 engines left the manufacturer on March 9, 1932. This engine used a 90-degree obstruct, with the valves located next to the pistons, directed upwards. The heads usually are not really flat, getting four spade-formed combustion chambers to support the motion from the valves. The gear-powered cam was found in the motor obstruct above the crankshaft and in between the tube banks, driving solid lifters that acted right on the valves. There have been two drinking water pumps – a single for every tube head.

The piston bore was 3.0625 in ., as well as the crank gave a stroke of three.750 in ., for a complete displacement of 221 cubic in .. Compression with stock heads was actually a conservative 5.5:1, which yielded 65 hp at 3,400 RPM.

Stock induction around the new flathead V8 was by way of a single tonsils downdraft carburetor as well as an aluminium consumption manifold that sat in between the banks of cylinders. An average stock 65-hp Flathead V8 should produce fuel economic climate at about 20 MPG.

This motor can be identified in the area by keeping track of the tube head studs, of which you will find 21 for each side. Later enhancements reduced the amount of studs to 17.

The flathead V8 was significantly below improvement during the early years, and alterations came annually. Early 1932 Design 18 motors experienced a reputation for using oil, porous castings, and chilling problems. In 1933, a change to aluminium heads raised the hp ranking to 75 for that Model 40. Cooling was revised and improved.

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

For 1935, the Design 38 obtained an up-to-date camshaft. With this point, over 2 thousand Ford flathead V8 engines was created for Ford automobiles and trucks, as well as for industrial use within other automobiles. By 1936, the engine was called a Model 68 and production approved the 3 million mark.

Inside the 1937 design year, the Ford V8 purchaser was provided a choice of aluminum or cast iron heads on the Design 78 motor. The cast iron heads offered a greater pressure ratio of 7.5:1 and ended in 94 horsepower when compared with 6.2:1 and 85 hp with aluminium heads.

Also in 1937, Ford introduced the smaller 136 cubic inch Model 74 engine, rated at 60 horsepower 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 motor became popular in race and then for general use since it provided much better energy economic climate compared to the bigger engine. 1938 saw continued creation of both the V8-85 and also the V8-60.

Second Era – 1939-1942

For 1939, Mercury additional a brand new version of the Ford flathead V8 style. The newest engine was larger, displacing 239.4 cubic inches by virtue of a for a longer time 3.1875-inch stroke. With a carry pressure proportion of 6.3:1, the brand new Model 99A provided 95 hp. V8 creation approved the 6 thousand device mark throughout this year.

Both 239 and 221 cubic inch engines switched to your 24-stud head bolt design for 1939, which makes them aesthetically distinct from engines made before now. Production continued in 1940 and 1941 with few modifications. Mercury customers wwmlyd the 239, and Ford customers got the V8-85.

By the start of 1942, America experienced entered the Second Planet Battle, and very couple of civilian vehicles of any kind were produced before Ford transitioned all of its services to the battle work. Needless to say, many motors including V8s had been created through the war to energy different military services automobiles, but additional development essentially ceased until the end from the war.

The time period right following the war had been a growth time for automakers as pent-up need for new vehicles was pleased. However, automakers just cranked up creation of 1942 designs till new vehicles may be created. Ford deserted the V8-85, providing all Ford and Mercury automobiles the 239 cubic inch engine, now compressing at 6.8:1 and ranked at 100 hp.
