Produced for Dodge, this vintage film explains the new “Red Ram” hemispherical V-8 engine, one of the A-engine series. The A engine family was a modern, efficient, and durable design produced from 1956 through 1966; the LA series of V8 engines was based on a lightweight casting of the A engines, appearing in 1964. The A and LA blocks are similarly sized and hard to tell apart from the outside, but the A’s polyspherical heads were considerably larger than the LA’s heads. It was an overhead valve design with dome-shaped heads. Dodge wrote, “So durable are they that the standard 25,000­ mile laboratory tests for wear had to be changed to 50,000-mile and 100,000-mile checks-because no discernible wear showed up until long past the 25,000-mile figure.”

As the narrator says, “During the years of defining, developing and perfecting the Red Ram it has come through thousands of hours of tests in the laboratory and on the road. It’s proven its performances. The new Red Ram develops a full 140 horsepower at 44 revolutions per minute as seen at mark 0:40. It produces more horse power per cubic inch displacement than any other engine in the America. At mark 0:50, the Ram’s power is tested on the road. It can run more than 100 miles per hour and can cruise along the highways with endless of hours with a smoothness and quietness unbelievable. A Red Ram has plenty reserve power and plenty of pickup acceleration despair as seen at mark 1:00. At mark 1:12, it does this by using regular fuel. At mark 1:27, it is proven that the Red Ram has high efficiency in performance, power, speed and long life. The reason for this is seen from mark 1:25. The combustion chamber is seen here and heat energy loss is also noted in the combustion chamber and reason for its shape. A little experiment on heat loss through the shape of the compartment chamber is conducted at mark 2:45. There are 2 containers here which are immersed into ice water and through thermometer reading with time, heat loss is measured. Likewise in automobile engines, combustion chambers that are not hemispherical, waste heat through the larger surfaces as seen at mark 3:45. But in the Red Ram the heat is turned into extra and working power as seen at mark 3:50. The gas has ideal place to work and to work efficiently. A slow motion animation is seen at mark 4:00. Here the cause of the design of the ordinary combustion chamber with the spark plug on one side makes burning time to be longer due to long distance covered by the flame. At mark 4:20, the spark plug is located at the center and the result is a smooth even power thrust as seen at mark 4:42 on engine. The Red Ram has a high compression ratio of 7.1 to 1 as seen at mark 4:55. Another tremendous advantage of the hemispherical combustion chamber is the high biometric efficiency as seen at mark 5:11. It is the ability of the engine to inhale the maximum amount of fuel and air mixture and exhale the exhaust gases also in the shortest possible time as seen at mark 5:23.

The volumetric efficiency of the red ram is unsurpassed as seen at mark 5:35. The exhaust metal hole is seen at mark 5:55 and how gases are burnt in the compartment. The intake metal hole is divided into 2 sections as seen at mark 06:08. At mark 6:30, each red ram cylinder has its own exhaust passage leading to the exhaust metal hole. The outlet of each metal hole is connected with the pipe. This enables for the smoothness and quietness of the Red Ram engine as seen at mark 6:57. Another reason for the brilliant action of the red ram is seen at mark 7:05. The Red Ram also has a high mechanical efficiency as seen at mark 7:50. In the red ram engine, the distance of travel is reduced as seen at mark 8:10 and this short stroke consequently means less wear. The Red Ram engine has many additional features and improvements as all are listed at mark 8:44.
