How much horsepower does a Dodge Polara have?

The Dodge Polara did not have a single horsepower rating; power varied by year and engine, ranging from roughly 230–275 horsepower in base configurations up to 425 horsepower with the top‑of‑the‑line 426 Hemi.


To understand how much horsepower a Polara might have, it helps to know that the model spanned several generations (roughly 1960–1973) and could be equipped with a wide range of V8 engines. The numbers below reflect representative outputs for common engine configurations found in Polara models over the years, with exact figures varying by year, carburetion, and emission controls.


Representative engine options and horsepower ranges


The following engine types illustrate typical factory output you might encounter in a Dodge Polara. Exact numbers depend on the specific year and configuration.



  • Small-block V8 engines (e.g., 318) — approximately 230–275 hp

  • Big-block 383 V8 — approximately 270–335 hp

  • 426 Hemi — 425 hp

  • 440 Magnum/440 with multiple carburetion setups — roughly 375–425 hp

  • 440 Six-Pack (three two-barrel carbs) — about 390 hp in factory ratings


Note: These figures are representative ranges. The exact horsepower on a specific Polara depends on the model year, engine code, and any accompanying performance packages or emission-related tuning.


Notable high-performance configurations


Some Polara models were equipped with the era’s top performers, offering the highest factory horsepower available for the chassis. The most powerful factory option was the 426 Hemi, rated at about 425 hp. Other high-performance setups included variations of the 440 with multiple carburetion configurations, which could approach the upper end of the 400 hp range depending on year and spec.


For enthusiasts and collectors, verifying horsepower on a particular Polara involves checking the engine code, the fender tag or build sheet, and the window sticker or factory catalogs for the exact year and option package.


How to verify horsepower on a specific Polara


To determine the exact horsepower of a particular Dodge Polara you’re evaluating, use these steps:



  • Identify the engine code and displacement stamped on the engine block.

  • Check the fender tag or build sheet for the original option codes and horsepower ratings.

  • Reference period Mopar catalogs or brochures for the specific year and trim level.

  • If available, review the vehicle’s factory window sticker or documentation from restoration work for precise figures.


Keep in mind that aftermarket modifications, wear, and emission-control updates can alter actual measured power versus factory ratings.


Summary


In short, the Dodge Polara’s horsepower varied widely by year and engine. The lineup ranged from around 230–275 hp for base small-blocks to up to 425 hp with the 426 Hemi, with other big-block and multi-carb setups (such as the 440) occupying the intermediate to high end of the spectrum. For a precise figure, identify the exact year and engine code, then consult factory documentation or verified reference materials.
