Did Dodge make a 400 cubic inch motor?
Yes. Dodge, as part of Chrysler, built a 400 cubic inch V8 as part of the big-block family. This displacement was offered in several Dodge models mainly in the late 1960s and into the early 1970s.
Background and context
The 400 cubic inch engine was a member of Chrysler’s big-block lineup, often referred to in automotive circles as part of the RB/B-family of horsepower-focused V8s. It shared engineering with other large-displacement Mopar V8s, and it appeared in Dodge cars as an option for buyers seeking strong performance without stepping up to its larger siblings. Its production and availability varied by year and model, reflecting the broader shifts in American muscle and emissions regulations during that era.
Origins within the engine family
The 400 cu in V8 was developed as part of Chrysler’s strategy to offer a high-displacement engine within its big-block lineup. It provided a mid-range option in the lineup—more torque and power than the smaller big-blocks, but occupying a distinct niche from the largest displacements like the 440 and the legendary Hemi. As with other Mopar big-blocks, it was used in performance-oriented and higher-trim Dodge models, as well as some full-size cars.
Where it appeared in Dodge models
In Dodge’s catalog, the 400 cubic inch V8 found its way into several models during the era when big-block options were popular. The engine was commonly paired with Dodge B-body platforms and other Dodge offerings of the period, and it was available in standard and higher-performance configurations depending on the year and package. Enthusiasts often associate the 400 with mid-to-late-1960s through early-1970s Dodge ownership, where buyers could opt for more power without moving to the largest displacement engines.
- Full-size Dodge models such as Coronet/Polara/Monaco lines during the late 1960s and early 1970s.
- Dodge muscle-oriented or higher-trim performers within the era, where customers could select a big-block option for enhanced performance.
- Occasional combinations in other Dodge body styles as part of package options, rather than as a standard base engine.
Before listing notable examples, note that model availability varied by year and trim. The 400 was not a universal option across every Dodge model in every year, but it appeared in a number of Dodge offerings during its production window.
These appearances reflect Dodge’s broader strategy to offer a big-block option within its lineup, giving buyers a middle-ground between smaller big-blocks and the larger, more famous displacements.
What to look for today if you’re researching or restoring
If you’re evaluating a vehicle or an engine for restoration, identifying a Dodge 400 cu in V8 typically involves cross-referencing the block casting codes, engine stamping numbers, and the vehicle’s VIN/Build Sheet. While the exact codes can vary by year and plant, the presence of a big-block designation and displacement stamp is a reliable starting point. Consulting period Mopar brochures, club documentation, or restoration guides can provide year-by-year specifics to confirm a particular engine’s origin.
Summary
Dodge did manufacture a 400 cubic inch V8 as part of Chrysler’s big-block family, and it showed up in several Dodge models primarily in the late 1960s and early 1970s. It offered a balance of power and size within Mopar’s performance spectrum, standing between smaller big-blocks and the larger displacements. For collectors and restorers, precise year-model matching relies on engine castings and build documentation, as availability varied across years and Dodge trims.
Final takeaway
In short: yes, Dodge did produce a 400 cubic inch engine, and it remains a notable part of Mopar’s late-60s to early-70s big-block era. If you’re chasing one, focus on Mopar big-block documentation and engine-build codes to confirm a specific vehicle’s configuration.
