Is a Dodge 440 a big block?
Yes. The Dodge 440 is a big-block V8 from Mopar, part of Chrysler's classic large-displacement engine family.
What defines a big-block engine
Big-block engines are defined by their larger displacement, heavier block construction, and a focus on high torque output. For Mopar, the big-block family includes engines designed to deliver strong low-end power for performance cars and heavy-duty applications. The 440 cubic inch engine is a member of this family and exemplifies the era's emphasis on muscular performance.
Key characteristics that define Mopar big-block engines include the following:
- Large displacement relative to small-block engines of the era
- Thicker, heavier block casting designed to handle higher torque and sustained use
- Higher-compression options and performance packages; used in muscle cars and trucks
- Distinct physical characteristics and identification cues (block code RB for many Mopar big-blocks and the 440 variants)
In summary, the big-block designation for the 440 is about displacement, durability, and intended use in higher-torque applications.
The Dodge 440 in Mopar's lineup
The 440 is part of Mopar's big-block family, widely used in Dodge and Plymouth models during the late 1960s and early 1970s. It offered a more affordable performance option alongside the era's top-line Hemi engines and powered a range of models designed for drag racing and street performance. Some 440s were equipped with performance packages such as multi-carburetor setups often referred to as a "Six-Pack," which boosted peak horsepower and throttle response. This combination helped establish the 440 as a staple of Mopar muscle cars during the period.
Popular Dodge models that used the 440 included the Charger, Challenger, and various Coronet/Satellite variants, with many customers choosing the 440 for its balance of power and value.
- Dodge Charger (R/T and performance variants)
- Dodge Challenger (R/T and other performance trims)
- Dodge Coronet and Super Bee variants
- Broader Mopar applications in Plymouth-based models shared the same big-block platform
Today, the 440 remains a centerpiece for collectors and enthusiasts, with many rebuilt, restored, or crate-powered engines continuing to drive the legacy of Mopar's big-block era.
Summary
In short, the Dodge 440 is a true big-block V8—a large-displacement, torque-oriented engine that played a central role in Mopar's performance lineup during the muscle car era. Its enduring popularity among collectors, hot-rodders, and vintage racers underscores its significance in automotive history.
Is a 383 and a 440 the same block?
So it's just a different animal these are different animals. So that goes in regards also to the other blocks you have your 440.
Is the 440 a V8?
Chrysler 440 was a big-block V8 engine introduced in 1966 as part of the RB (raised block) engine family, and it quickly became a cornerstone of Mopar performance through the late 1960s and early 1970s.
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. |
