How many liters is a Dodge 440 engine?
The Dodge 440 engine is a 440 cubic inch V8, which translates to about 7.21 liters in displacement. In everyday reference, it's typically rounded to 7.2 liters.
More context: The 440 is part of Chrysler's Mopar big-block family and was used in Dodge performance cars starting in 1965 and continuing through the late 1970s. Understanding the liter figure helps readers compare engine sizes across brands that use the metric system.
Displacement in numbers
To see exactly how the conversion works and what enthusiasts typically quote, consider these quick facts:
How the conversion works
One cubic inch equals 0.016387064 liters. Multiply by 440, and you get about 7.2103 liters. In typical automotive references, this is rounded to 7.2 liters.
Note on rounding: While 7.210 L is the precise figure, most catalogs and discussions present it as 7.2 L for simplicity.
With that conversion in mind, here are the key numbers most people cite when discussing the Dodge 440's size:
- Displacement: 440 cubic inches (ci)
- Liters: approximately 7.21 L (7.210 L)
- Common shorthand: 7.2 L
- Production timeline: introduced in 1965; used in Dodge big-blocks through the late 1970s
In short, the Dodge 440's size is best understood as a 7.21-liter engine, widely rounded to 7.2 L in most references.
Historical context for readers
The 440 was a staple of Mopar's big-block lineup during the muscle car era. It arrived in 1965 and became a workhorse for high-performance Dodge models, later facing the emission and insurance changes that affected horsepower in the late 1970s. For collectors and restorers, the liter figure provides a quick way to compare to other V8 offerings from rival makers.
Summary
The Dodge 440 engine displaces 440 cubic inches, which converts to roughly 7.21 liters — commonly rounded to 7.2 L. Introduced in 1965, it remains a benchmark in the Mopar big-block family and a touchstone for classic American muscle cars.
Was the 440 faster than the 426 Hemi?
The **440 Six-Pack was often faster in stock form, particularly in the quarter mile, but the 426 Hemi had a higher potential for power when modified. Stock 440 Six-Packs generally had better out-of-the-box performance due to how they were tuned and how they hooked up from the line, while the Hemi was a detuned race engine that could be built to produce significantly more power than the 440 with modifications.

| Feature | 440 Six-Pack | 426 Hemi |
|---|---|---|
| Stock Performance | Often faster in stock form (e.g., quarter-mile drag racing). | Slower in stock form compared to the 440 Six-Pack. |
| Power Potential | Lower power potential than the 426 Hemi when both are modified. | Higher power potential when modified, especially with race-spec builds. |
| Factory Advantage | Lower factory-rated horsepower but with better street-tuned performance. | Higher factory-rated horsepower but often struggled with traction in stock form. |
| Engine Design | Wedge head engine. | Hemispherical head engine with larger ports and valves. |

How many Litres is a 383 Magnum engine?
6.3 liters
With a displacement of 383 cubic inches (6.3 liters), this V8 was originally designed to bridge the gap between economy and high performance.
What is the difference between a 440 six pack and a 440 magnum?
The main difference is that the 440 Six Pack is a high-performance version of the 440 Magnum, featuring a triple-carburetor setup (three 2-barrel carbs) instead of a single 4-barrel carb. This results in more power (390 HP vs 375 HP for the Magnum) and a higher compression ratio. The Six Pack also includes other specific upgrades like a different camshaft, pistons, and a dual-point distributor, as well as a reinforced oil pan and K-frame skid plate.
440 Magnum
- Fuel delivery: One 4-barrel carburetor.
- Power: Approximately 375 HP.
- Torque: Approximately 480 LB-FT.
- Compression ratio: 9.5:1.
440 Six Pack
- Fuel delivery: Three 2-barrel carburetors (a "six pack" of barrels).
- Power: Approximately 390 HP.
- Torque: Approximately 490 LB-FT.
- Compression ratio: 10.5:1.
- Other differences:
- More aggressive camshaft.
- Different pistons, with valve reliefs.
- Special dual-point distributor.
- A deep oil pan and a K-frame skid plate for protection.
