In the history of automotive engines, it is impossible to overstate the importance of the V8 design. By splitting up the eight cylinders into two banks of four, engineers achieved a strong, yet lightweight unit which could fit into nearly all engine bays also sized to fit four or 6-cylinder engines.

Ford failed to invent the V8 engine, nevertheless it can be relatively stated that they introduced it into everyday use. Some Western marques and Cadillac experienced V8 motors years before Ford developed the engine that will yield affordable overall performance and create the basis for hot rodding.

Initially Generation – 1932-1938

The first from the Ford L-head (flathead) V8 engines left the manufacturer on Mar 9, 1932. This engine used a 90-level block, with the valves located next to the pistons, pointed up-wards. The heads usually are not really flat, having 4 spade-formed combustion compartments to accommodate the movement in the valves. The equipment-powered cam was located in the engine block higher than the crankshaft and involving the cylinder banks, driving strong lifters that acted entirely on the valves. There were two drinking water pumps – one for each cylinder head.

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

Carry induction around the new flathead V8 was with a solitary throat downdraft carburetor plus an aluminum consumption manifold that sat involving the banks of cylinders. A normal stock 65-horsepower Flathead V8 ought to yield energy economic climate at about 20 Miles per gallon.

This engine can be recognized within the field by keeping track of the tube head studs, in which there are 21 per side. Later on enhancements decreased the amount of studs to 17.

The flathead V8 was very much under development during the early years, and alterations came yearly. Earlier 1932 Design 18 engines had a track record of using oil, porous castings, and cooling issues. In 1933, a change to aluminum heads elevated the horsepower ranking to 75 for the Model 40. Chilling was also modified and enhanced.

1934 saw the advent of a two-barrel Stromberg carburetor, raising productivity to 85 horsepower inside the Design 40A. A cast metal crankshaft enhanced dependability. This is the era from the V8 notoriously recognized by bank robber Clyde Barrow within a letter to Henry Ford.

For 1935, the Model 38 obtained an up-to-date camshaft. By this point, more than 2 million Ford flathead V8 motors had been created for Ford vehicles and vehicles, and for commercial use in other vehicles. By 1936, the engine was known as a Design 68 and creation approved the 3 million tag.

Inside the 1937 model year, the Ford V8 purchaser was provided a selection 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 hp when compared with 6.2:1 and 85 horsepower with aluminum heads.

Also in 1937, Ford brought out smaller 136 cubic ” Model 74 motor, rated at 60 hp and 94 pound-feet of torque. This engine grew to become referred to as V8-60, and can be identified by the 17 head studs. This motor became popular in racing and then for general use because it provided better fuel economic climate compared to bigger motor. 1938 saw ongoing manufacture of both the V8-85 and the V8-60.

Second Generation – 1939-1942

For 1939, Mercury additional a brand new variant of the Ford flathead V8 design. The brand new motor was larger, displacing 239.4 cubic inches by virtue of the longer 3.1875-” cerebrovascular event. With a stock compression proportion of 6.3:1, the newest Model 99A offered 95 horsepower. V8 creation passed the 6 million unit tag throughout this year.

The 239 and 221 cubic ” motors switched to a 24-stud head bolt design for 1939, which makes them visually distinct from motors created before this time around. Creation continued in 1940 and 1941 with few modifications. Mercury buyers wwmlyd the 239, and Ford buyers received the V8-85.

By the start of 1942, America experienced came into the Second Planet Battle, and incredibly couple of civilian cars of any kind were produced before Ford transitioned all its services for the war effort. Needless to say, numerous engines including V8s had been produced through the war to power various military automobiles, but additional improvement essentially ceased until the end of the battle.

The period right right after the war was a boom time for automakers as pent-up need for new cars was satisfied. However, automakers simply cranked up manufacture of 1942 designs until new cars may be developed. Ford abandoned the V8-85, giving all Ford and Mercury vehicles the 239 cubic inch engine, now compressing at 6.8:1 and rated at 100 horsepower.
