What Is the 5.7 HEMI Engine?
The 5.7 HEMI is a 5.7-liter, 345-cubic-inch V8 from Chrysler’s modern HEMI engine family.
The engine is commonly associated with vehicles from Dodge, Ram, Chrysler, and Jeep, including applications such as the Ram 1500, Dodge Challenger, Dodge Charger, Dodge Durango, Chrysler 300 and various Jeep models.
The modern 5.7L HEMI is part of the Gen III HEMI family and has been offered in different configurations throughout its production history. Consequently, not every 5.7 HEMI engine is identical.
For example, output can vary according to model year, vehicle application, intake and exhaust configuration, engine calibration, cylinder-deactivation equipment, and other components.
For a current Ram application, the 2026 Ram 1500 lists the 5.7L HEMI V8 with 395 horsepower and 410 lb-ft of torque, paired with an eight-speed automatic transmission.

Why Buy a 5.7 HEMI V8 Engine?
There are several reasons the 5.7 HEMI continues to attract American truck and muscle-car enthusiasts.
1. Strong V8 Performance
The 5.7 HEMI provides a combination of horsepower and torque suitable for street cars, trucks, SUVs and performance projects.
2. Large Application Range
The engine has been installed in numerous Dodge, Ram, Chrysler and Jeep vehicles, making it a familiar platform for replacement and swap projects.
3. Excellent Aftermarket Support
The popularity of the Gen III HEMI has resulted in a large aftermarket for intake systems, exhaust components, camshafts, cylinder heads, pistons, rotating assemblies and other performance parts.
4. Suitable for Engine Swaps
A 5.7 HEMI can be an attractive option for classic-car and custom vehicle projects, provided the builder properly addresses engine management, wiring, fuel delivery, cooling, exhaust, transmission and mounting requirements.
5. Strong Torque Characteristics
The HEMI’s displacement and V8 configuration provide the low- and mid-range torque that many truck and muscle-car owners want.
Dodge itself describes the 5.7L HEMI as a V8 with a reputation for power and durability, and the engine has remained an important part of the brand’s performance heritage.
5.7 HEMI Crate Engine for Sale
A 5.7 HEMI crate engine is an attractive option when you want an engine that can be installed into a project without sourcing every major internal component individually.
Depending on the supplier and specification, a crate engine may be sold as:
- Complete engine assembly
- Long block
- Short block
- Replacement engine
- Remanufactured engine
- New engine
- Performance crate engine
- Turn-key engine
The exact contents of a crate engine vary significantly.
For example, some Mopar 5.7L crate-engine packages have included components such as the water pump, flywheel and clutch, oil pan, intake manifold, throttle body, fuel injectors and coil packs.
Other crate engines are supplied as long blocks and require the buyer to transfer or purchase accessories, intake components, fuel systems, electronics and other equipment.
New vs. Remanufactured vs. Used 5.7 HEMI Engines
When searching for a 5.7 HEMI engine for sale USA, you will typically encounter three major categories.
New 5.7 HEMI Engine
A new engine has not previously operated in a vehicle.
This can be an excellent option for a high-value restoration or performance build, but new engines can cost significantly more.
Remanufactured 5.7 HEMI Engine
A remanufactured engine has been rebuilt to specified standards. Depending on the supplier, machining, replacement components and testing may be included.
A remanufactured engine can offer a balance between price and reliability.
Used 5.7 HEMI Engine
A used engine is generally sourced from a vehicle that has been dismantled or salvaged.
Used engines can be more affordable, but the buyer should carefully verify mileage, condition, compression, oil pressure, vehicle history and warranty.
