In general, a 5.7 L Hemi crate engine costs roughly between $5,000 and $12,000, depending on configuration, supplier, and whether you’re buying a turnkey unit or an engine-only block.
Understanding what you’re buying
The 5.7 L Hemi crate engine comes in several configurations. A turnkey crate includes the engine plus electronics, wiring, sensors, and often a fuel system and ECU, ready to drop into a compatible vehicle. An engine-only crate (often a long-block) provides the core engine and essential components, but requires you to supply or reuse your own electronics and peripherals. Prices fluctuate with demand, supply chain conditions, and packaging.
Variants you’ll encounter
The following price bands reflect common configurations offered by Mopar and major aftermarket suppliers as of the current market. They are rough guidelines to help you plan, not fixed quotes.
- Turnkey crate engine (fully assembled with EFI, ECU, wiring harness, sensors, and mounting hardware): $9,000–$12,000
- Long-block style crate engine (engine-only, typically without ECU or fuel system): $6,000–$9,000
- Remanufactured or used options (rebuilt or second-hand units): $5,000–$7,000
Prices will vary by supplier, included components, and any added warranties or services. Shipping, taxes, and core charges can also affect the final out-the-door price.
Where to buy and how to compare
Buyers typically source a 5.7 L Hemi crate engine from Mopar’s official catalog, large auto parts retailers, or specialty crate-engine builders. It’s important to compare not just the sticker price but what’s included, warranty terms, lead times, and shipping costs.
- Mopar (official crate engines through the Mopar Performance catalog)
- Major retailers (e.g., Summit Racing, JEGS) that list 5.7 Hemi crate options
- Specialty crate-engine builders and remanufacturers
Before purchasing, confirm exact part numbers, whether the unit is built to your vehicle’s year and model, and what accessories are included. Ask about core charges and return policies, and request a written quote that itemizes the engine, installation hardware, and any required ECU/ harness components.
Practical considerations for buyers
Warranty and support
Look for a warranty that covers core failures, machined tolerances, and critical components. Warranty length and coverage vary by seller; some offer 12–24 months, others longer for higher-priced turnkey units.
Installation readiness
Decide whether you want a plug-and-play turnkey setup or a more DIY-friendly engine that you’ll mate to existing electronics. Confirm compatibility with your vehicle’s year, model, and emissions requirements, and budget for installation labor, gaskets, fluids, and testing after install.
Summary: The cost of a 5.7 L Hemi crate engine is highly configuration-dependent, with typical ranges from about $5,000 for rebuilt or engine-only units to roughly $12,000 for turnkey EFI-equipped engines. Prospective buyers should compare included components, warranty terms, and total costs (shipping, tax, core charges, and installation) across multiple reputable sellers.
