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.

Do you know specs on the cam used in the 2019 ram classic. everything would be nice , lift , adv. 50thou LSA…Thank you
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 average 16-19 around town, and can get 25-27 on the highway.
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.
You can cam it, but to do so you would need to deactivate the MDS in the PCM, change valve lifters from hydraulic to solid, and install a camshaft phase limiter on the engine. If you check out COMP cams they sell packages and can point you in the direction of the right cam for you.
Also i forgot to mention there are oil plugs as well for the MDS deactivation. Modern Muscle Xtreme sells a MDS delete kit that supplies you with everything you need to get rid of the MDS.
WAT CAM SHAFT Sensore& Crankshaft sensor do I need too use
I have a 2011 chrysler 300c eagle Hemi with rear resonator deleted. Thinking about doing shorty headers , cold air intake and tuner chip. Is this advisable? And if so how much horsepower gains could I expect?
Cold Air package – any filter that remains under the hood, and I don’t care if there’s a barrier wall or not, is pulling in hot air. This is why dyno pulls are almost always with the hood open. Leg Maker has a system that puts the filter UNDER the sheet metal panel, where your stock airbox sits now. This, IMHO, is the best design of aftermarket CAI kits. You’ll see about a 5-10HP increase from this CAI kit.
Shorty headers – you should see about the same…a 5-10HP improvement over the factory “log” manifolds.
“Chip” (actually referred to as a tune) – I highly, highly,. HIGHLY recommend HP Tuners. I invested in their system for my ’14 Challenger and have never been happier, learning to tune some of the variables myself and get better fuel economy, throttle response, etc. When the time comes for major upgrades, there are plenty of Tuners out there, who tune for a living, that can “remote-tune” and “email-tune” your car. All you do is drive it and log data (with HPTuners free software), email your logs to your tuner and he/she will email back your next tune file which you’ll simply flash to the PCM and TCM. Since your car is an ’11, you don’t have to unlock your PCM…which would be extra $$. There are plenty of YouTube videos about tuning Gen 3 Hemis with HPTuners.
Did Chrysler revise the lifter design on the eagle 5.7? I’ve heard 2016 and up have a new design, less prone to roller failure.
They have not but johnson lifters makes a lifter to solve the issue
Can I run a supercharger on my 2016 5.7 on stock internals?
Yes, but keep the boost to a modest level. The major supercharger mfgs have done their homework and designed their off-the-shelf systems to keep your engine safe, yet offer a significant increase in HP and, MOST IMPORTANTLY, torque to get our pleasure boats moving. 🙂
I have 2009 Jeep 5.7 Hemi need motor do to Chian let go hit the valves. What year is the 5.7 Gen 111 up too I can buy and replace the Engine thanks.are they the same up too what years.
