Chrysler IV-2220 fighter plane engine
Chrysler's IV-2220, a 2,500 horsepower hemi engine designed for use in World War II fighter planes.Chrysler's first hemispherical-head engine was the IV-2220, a 2,500 horsepower, supercharged, turbocharged V-16. Chrysler had begun work on the engine around 1940, and presented their idea to the United States Army Air Corps, a World War II era predecessor to the modern-day US Air Force. The engine was intended to be installed in Republic P-47 fighter planes. It first flew in 1945, but it never went into production. By that time, the war was ending, and the need for such an engine was dwindling as the jet age approached. One of these engines is on display at the New England Air Museum in Bradley Airport, Windsor Locks, CT

Does anyone know if the Charger is available in a two door?

Don,
The current Charger is a four door sedan only.
And the Magnum is essentially a station wagon Charger.

Chrysler "Early Hemi" engine
An "Early Hemi" engine, recently rebuilt.In the late 40's, Chrysler realized that its current line of flat head 6 and 8 cylinder power plants weren't going to make the grade when matched against the new more powerful V8 designs Cadillac and Oldsmobile were planning to introduce during the 1949 model year. They also knew larger engines capable of producing more horsepower would be required to haul around the new heavy weight barges Chrysler currently had on their drawing boards. Chrysler needed an engine capable of leveling the playing field.
Chrysler's engineers began to research possible V8 engine designs, looking for something that might be capable of producing real horsepower. Eventually, the decision was made to go with a conventional V8, similar to those being developed by Ford and GM. However, Chrysler would tap its previous military design experience for a unique twist on the conventional V8. In 1951, Chrysler introduced the FirePower engine -- their first hemispherical-head engine for the consumer market, fondly referred to by enthusiasts as the "Early Hemi". Though Chrysler made reference to the engine's "hemispherical" combustion chambers, the word "Hemi" was not overtly used to market the engine. The term "Hemi" was more frequently applied by the late 1950's. This was most likely due to its colloquial use by Chrysler engineers, and dragracers of the era.
During the 50's, Chrysler Corporation had a decentralized approach to engine building. Each division (Chrysler, Dodge, and DeSoto, and Plymouth) had its own engine manufacturing facility. Given the freedom to do so, each adopted a slightly different variation of the basic Hemi design. Chrysler's FirePower engine was accompanied by DeSoto's FireDome in 1952, and Dodge's Red Ram design in 1953. Plymouth would use polyspherical-shaped cylinder heads, also known as "semi-hemis".
This decentralized and inefficient manufacturing approach, coupled with the expense of manufacturing a complicated design like the Hemi, eventually spelled the downfall of this mighty powerplant. Production ceased with the completion of the 1958 model year in favor of a new simplified corporate-wide wedge head design, known as the Chrysler "B" engine.

The 426 Hemi A 426 Hemi engine.In 1964, Chrysler introduced their new 426 Hemi. The 426 had not been designed primarily for consumers, but for NASCAR racing. Car manufacturers were well aware that racing victories bolstered their high-performance images, and significantly increased sales -- hence the saying: "What wins on Sunday, sells on Monday". So, they had been making engines specifically designed to win NASCAR races. NASCAR officials countered by requiring manufacturers to sell a certain number of a model to the public before they could race them, a process known as homologation. In 1964, if a car was to be entered in a NASCAR race, 500 cars of that same model had to be sold to the public. At the time, this ensured that stock car racing used only "stock" cars. The 426 Hemi was a clear success; Hemis placed 1st, 2nd, and 3rd in the 1964 Daytona 500. This instant domination led NASCAR to increase the homologation requirement from 500 to 1,000. So, Chrysler initiated the "Street Hemi" program. A detuned version of the 426 engine became a publicly-available production option in certain Dodge and Plymouth models. The program was successful -- Chrysler was able to race Hemis again in the 1966 season. That year, a Hemi-powered Dodge Charger would win 14 first-place finishes and clinch the NASCAR Grand National championship. The 426 Hemi was discontinued after 1971.  |

Heck no. I just haven't posted anything. It makes me ill that I couldn't get my hands on the 1952 Saratoga that sat in the garage at my mother-in-law's family farm. They say it was one fast car in it's day. It's gone now, destination unknown.
