What did the Dodge 440 come in?

The Dodge 440 engine was offered across a broad spectrum of Mopar models in the late 1960s and early 1970s, including full-size B-body cars like the Polara/Monaco and Coronet, the performance-focused lines such as the Super Bee and GTX, and the iconic muscle cars Charger and Challenger, with high-performance variants like the 440 Magnum and Six-Pack versions.

Contextually, the 440 cubic-inch V8 became a cornerstone of Dodge’s big-block lineup during the muscle-car era. It powered a variety of body styles—from family sedans to two-door performance machines—before emissions regulations and rising insurance costs trimmed back horsepower offerings in the early 1970s.

Legacy and impact

The 440’s footprint across Dodge’s lineup helps define the late-1960s/early-1970s muscle car story: big displacement, strong power, and aggressive styling. Though output waned with tightening regulations and rising insurance costs, the 440 remains a defining chapter in Mopar performance history.

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.
