Did Dodge make a flathead engine?
As a seasoned auto repair expert at Kevin's Autos, I often get asked about the history of engines, especially those that have left a mark on automotive engineering. One such question is whether Dodge ever made a flathead engine. The answer is a resounding yes! Dodge was a significant player in the flathead engine era, producing these engines for decades. Let’s dive into the details of Dodge’s flathead engine legacy.
What Is a Flathead Engine?
A flathead engine, also known as a side-valve engine, is a type of internal combustion engine where the valves are located beside the pistons in the engine block rather than in the cylinder head. This design was popular in the early to mid-20th century due to its simplicity, reliability, and ease of manufacturing. However, it eventually fell out of favor as overhead valve (OHV) engines became more efficient and powerful.
Dodge’s Contribution to Flathead Engine History
Dodge, a brand under the Chrysler Corporation, was a prominent manufacturer of flathead engines. These engines were used in a variety of vehicles, including passenger cars, trucks, and even military vehicles during World War II. Here are some key highlights of Dodge’s flathead engine history:
- Flathead Six: One of Dodge’s most famous flathead engines was the inline-six-cylinder engine, often referred to as the "Flathead Six." This engine was introduced in the 1930s and became a workhorse for Dodge vehicles. It was known for its durability and smooth operation.
- Military Applications: During World War II, Dodge produced flathead engines for military vehicles such as the Dodge WC series trucks and the Power Wagon. These engines were valued for their reliability in harsh conditions.
- Post-War Era: Dodge continued to use flathead engines in its vehicles well into the 1950s. However, as automotive technology advanced, the flathead design was gradually replaced by more efficient overhead valve engines.
Why Did Flathead Engines Decline?
While flathead engines were revolutionary in their time, they had limitations that led to their decline:
- Lower Efficiency: The side-valve design restricted airflow, resulting in lower power output and fuel efficiency compared to overhead valve engines.
- Heat Management Issues: Flathead engines were prone to overheating due to the placement of the valves and the combustion chamber design.
- Technological Advancements: The development of overhead valve and overhead camshaft engines offered better performance, efficiency, and reliability, making flathead engines obsolete.
Conclusion
Dodge played a significant role in the history of flathead engines, producing reliable and durable engines that powered a wide range of vehicles. While the flathead engine is no longer in use today, it remains an important chapter in automotive history.

Frequently Asked Questions
What was the last big block engine made?
The Final Big-Block: The GM Vortec 8100 V8
After the discontinuation of the Chevrolet 454 big-block in 2001, General Motors still saw potential in a gigantic, fuel-guzzling V8. The Vortec 8100 was shoehorned into various civilian GM models, and it was also used in commercial applications.
Did Chevy make a flathead engine?
Cadillac, GMC, Oldsmobile and Pontiac all had flathead (side valve) engines. GMC until 1939, Cadillac and Oldsmobile until 1949 (although Olds had a flathead 6 available in '49 and '50) and Pontiac until 1955. Buick and Chevrolet never had flathead engines.
What was the problem with the flathead engine?
The Flathead was also a very low compression engine, with Fenske noting the earliest 65-hp 3.6-liter variant had a compression ratio of just 5:1. Increasing compression could help boost power, but the flat cylinder head design meant doing so would restrict airflow further.
What was the most powerful flathead engine?
At an amazing speed of 302.204 m.p.h., a car powered by a supercharged 700 horsepower Ford flathead V8 holds the land speed record for its class at Bonnyville salt flats. The car was developed and driven by Ron Main of Chatsworth, California.
When was the last flathead engine made?

Did Cadillac make a flathead V8?
In 1937, the new monobloc flathead gained 24 cu in (390 cc) in Cadillac V-8 models to 346 cu in (5.7 L), while the LaSalle straight-8 of 1934–1936 that originated from Oldsmobile actually was replaced with the 1936 smaller 322 cu in (5.3 L) version at 125 hp (93 kW).
Are flat head engines any good?
Advantages. The advantages of a sidevalve engine include: simplicity, reliability, low part count, low cost, low weight, compactness, responsive low-speed power, low mechanical engine noise, and insensitivity to low-octane fuel.
What was Ford's big block engine?
The Ford 385 engine family (also called "Lima") is a series of "big block" overhead valve (OHV) V8 engines designed and manufactured by Ford Motor Company. The family derives its 385 name from the 3.85-inch (98 mm) stroke of the 460 cubic-inch V8 introduced in 1968.
Did Pontiac make a big block engine?
Pontiac differed from other GM Divisions and most other manufacturers in producing only a single sized V8 casting, rather than adding a larger big block to its line-up. The external dimensions of all their V8s, from 326–455 cu in (5.3–7.5 L) were the same.
Why did they stop making flathead engines?
The simplicity, lightness, compactness and reliability might seem ideal for an aero-engine, but because of their low efficiency, early flathead engines were deemed unsuitable.
