How much horsepower does a Chrysler 400 have?
There is no production model named “Chrysler 400,” so there isn’t a single horsepower figure to quote for that name. Horsepower depends on the engine and year. If you meant a different Chrysler model or can share a specific year/trim, I can provide the exact figure for that configuration.
Does a Chrysler 400 exist?
The name Chrysler 400 does not correspond to a current or widely recognized production model from Chrysler. The closest real model people often confuse it with is the Chrysler 300, whose power output varies by engine and year. Below is a quick guide to the kinds of engines you might encounter in Chrysler’s lineup and how they translate to horsepower.
Closest real model and typical engines
Here are the engines most commonly found in Chrysler’s modern sedans and their approximate horsepower, which helps explain why a single “Chrysler 400” figure isn’t meaningful.
- 3.6L Pentastar V6 — about 292 horsepower
- 5.7L Hemi V8 — roughly 363–370 horsepower in most older 300/Chrysler variants
- 6.4L Hemi V8 — roughly 470–485 horsepower in higher-performance trims
In other words, horsepower for a vehicle with a Chrysler badge can vary widely depending on the engine choice and model year. If you have a specific year and trim in mind, I can pull the exact figure for that configuration.
Horsepower by engine family (typical figures)
To give a broader sense of how a Chrysler model’s power can differ, here are common engine families and their typical output ranges. Note that exact numbers can differ by year, tuning, and market, so use this as a guide rather than a single specification.
- 2.4L I4 (less common in newer mainstream models) — around 184 horsepower
- 3.6L Pentastar V6 — around 292 horsepower
- 5.7L Hemi V8 — roughly 363–370 horsepower
- 6.4L Hemi V8 — about 470–485 horsepower (high-performance trims)
- 6.2L Supercharged Hemi (Hellcat/Demon family) — 707–808 horsepower in Challenger/Charger variants; these engines are not used in standard Chrysler sedans like the 300
These ranges illustrate why there isn’t a single horsepower figure for a “Chrysler 400.” The exact number depends on the engine, year, and trim you’re considering. If you provide the specific year and model you have in mind, I’ll give you the precise horsepower rating for that configuration.
What to do next
If you can share the exact year and trim (for example, “Chrysler 300, 2018, SRT model” or another configuration), I’ll pull the precise horsepower specification for that vehicle.
Summary
The Chrysler 400 does not exist as a current production model, so there is no definitive horsepower number for that name. horsepower in Chrysler vehicles depends on the engine and year, with common figures ranging from about 184 hp (entry engines) to roughly 485 hp in high-performance setups, and much higher in non-Chrysler variants in the broader Hemi family. For an exact figure, please provide the year and trim you’re asking about.
What is a Chrysler 400 engine?
The 400 cu in (6.6 L) B engine was introduced in 1972 to replace the venerable 383, and were power-rated via the net (installed) method. Chrysler increased the bore size of the 383 to create the 400. Its bore of 4.342-inch (110.3 mm) was the largest used in any production Chrysler V8 at the date of its introduction.

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 much horsepower does a 383 Chrysler have?
The horsepower of a Chrysler 383 engine varies, but its high-performance versions, like the 383 Magnum, were typically rated at 335 horsepower. However, a two-barrel version had about 275 horsepower, and some standard engines were rated lower due to emissions controls in later years.

- 383 Magnum (performance): This version, common in muscle cars, is rated at 335 horsepower.
- 383 two-barrel: A standard version with a two-barrel carburetor was rated at around 275 horsepower.
- Lower-powered versions: For 1971, a drop in compression for emissions reduced the horsepower of a standard 383 to 300 hp.
- Actual output: Some sources suggest that factory horsepower ratings, particularly for the 383 Magnum, may have been conservative, and actual performance was higher.
