In the history of car engines, it is impossible to overstate the significance of the V8 design. By splitting up the eight cylinders into two banks of four, engineers achieved a strong, yet lightweight unit that may fit into the vast majority of motor bays also size to fit four or 6-cylinder engines.

Ford did not create the V8 motor, nevertheless it can be relatively stated that they brought it into everyday use. Some European marques and Cadillac had V8 engines decades before Ford created the motor that would produce inexpensive overall performance and create the foundation for hot rodding.

First Generation – 1932-1938

The initial from the Ford L-head (flathead) V8 engines left the manufacturer on Mar 9, 1932. This engine utilized a 90-level obstruct, with all the valves located near the pistons, directed up-wards. The heads are not really flat, having four spade-shaped combustion chambers to accommodate the motion in the valves. The gear-powered camera was located in the motor block above the crankshaft and involving the cylinder banking institutions, traveling strong lifters that acted directly on the valves. There have been two drinking water pumping systems – one for each cylinder head.

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

Stock induction around the new flathead V8 was by a solitary tonsils downdraft carburetor as well as an aluminium consumption manifold that sat between the banking institutions of cylinders. A normal stock 65-horsepower Flathead V8 ought to produce fuel economic climate at about 20 MPG.

This engine can be recognized in the field by keeping track of the cylinder head studs, of which you will find 21 per side. Later on enhancements reduced the number of studs to 17.

The flathead V8 was greatly under improvement during the early many years, and alterations arrived yearly. Early 1932 Design 18 motors had a track record of utilizing oil, permeable castings, and cooling problems. In 1933, a change to aluminum heads elevated the hp rating to 75 for that Design 40. Cooling was also modified and enhanced.

1934 saw the advent of any two-barrel Stromberg carburetor, raising output to 85 horsepower within the Model 40A. A cast metal crankshaft improved dependability. It was the era of 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 million Ford flathead V8 motors was produced for Ford automobiles and vehicles, and then for industrial use within other automobiles. By 1936, the motor was called a Design 68 and production passed the 3 million tag.

In the 1937 model year, the Ford V8 purchaser was offered a choice of aluminium or cast iron heads on the Design 78 engine. The cast iron heads provided an increased pressure ratio of 7.5:1 and ended in 94 horsepower compared to 6.2:1 and 85 horsepower with aluminium heads.

Also in 1937, Ford introduced the smaller 136 cubic inch Model 74 motor, rated at 60 horsepower and 94 pound-feet of torque. This motor grew to become called the V8-60, and can be recognized by the 17 head studs. This engine became well-known in race as well as for general use because it supplied better fuel economic climate compared to the larger engine. 1938 saw ongoing creation of both V8-85 and the V8-60.

Second Era – 1939-1942

For 1939, Mercury additional a whole new variant of the Ford flathead V8 design. The brand new engine was bigger, displacing 239.4 cubic in . by virtue of any longer 3.1875-” cerebrovascular event. In a carry pressure ratio of 6.3:1, the brand new Design 99A provided 95 hp. V8 creation approved the 6 million device mark in this year.

Both 239 and 221 cubic ” motors switched to some 24-stud head bolt pattern for 1939, which makes them aesthetically unique from motors made before this time around. Creation continued in 1940 and 1941 with few changes. Mercury buyers wwmlyd the 239, and Ford customers got the V8-85.

By the start of 1942, America had came into the Second World War, and extremely couple of civilian vehicles for any kind were produced before Ford transitioned all its facilities for the battle work. Of course, many motors such as V8s had been created through the war to energy various military automobiles, but further development basically ceased until the end from the war.

The time period right after the war had been a growth time for automakers as pent-up need for new vehicles was satisfied. Nevertheless, automakers just cranked up manufacture of 1942 designs till new vehicles may be developed. Ford deserted the V8-85, providing all Ford and Mercury vehicles the 239 cubic ” engine, now compressing at 6.8:1 and rated at 100 horsepower.
