2009+ Mopar Gen. III 5.7L Hemi Eagle Engine Guide: Bore & Stroke, Cylinder Heads, Cam Specs & More

(Image/Stellantis)

When Chrysler announced it was bringing back the legendary Hemi in the early 2000s, it was a big deal. This new series of Hemi engines is often referred to as the “Gen. 3” after the first generation FirePower (1951-59) and second generation Elephant 426 (1964-71).

Note: This Spec Guide is part of a series of Hemi Engine Spec guides we’re putting together. See Other Hemi Engine Spec Guides Here.

Introducing the Eagle

After the initial 5.7L Gen. III Hemi was introduced in 2003, Chrysler made its first major revisions to the 5.7L Gen III Hemi with the appearance of the Eagle version engine starting in 2009.

This engine, referred to as the Eagle, introduced Variable Cam Timing (VCT) and combined that with the Multiple Displacement System (MDS) that demanded major changes to the cylinder block, cylinder heads, and other components. The cylinder heads feature improved intake port flow over the previous 5.7L heads as well as significant changes to combustion chamber size and shape. 

This Engine Guide is Specifically for the 2009+ Mopar Gen. III 5.7L Hemi “Eagle” Engine.

VIN Identification: The 8th digit in the VIN designates the engine—for the 5.7L Eagle, the letter is T.

    Hi, What gas mileage can you get with this 5.7L eagle motor. Looking for a possible replacement for a 413 wedge 1959 crown imperial 6.7L BB. Dont want to have to re engineer the whole car though. Thanks Chris Perth Australia.

    • Hey Chris, that can be tough to answer definitively, because the engine is only part of the mileage equation. You still need to account for things like vehicle weight and gearing. That said, a quick online search reveals that 5.7L-equipped Chargers are getting anywhere between 15 to 19 mpg city and 23 to 25 highway, depending on the year and configuration.

      But again, that’s probably not a good benchmark because we don’t know much about your setup–again, you’ll have to account for your transmissio and rear end gearing as well. Hopefully this gets you in the ballpark–Good luck with the swap!

    I have an 07 charger Rt (5.7)..i believe it to be all original. I’ve been told that I can not cam this motor because of the MDS and VVT. Disappointed because at the time I was. s putting new heads on and it would have been the right time to cam. Is there really truth to this or did I just run into mechanics that didn’t want to deal with it… And if so, can you tell me what cam I could upgrade to with minimal effort and most gain (yes, every mechanics dream). Ty in advance for your time and effort.
