Used 5.7 HEMI engines typically sell for roughly $2,500 to $9,000, depending on whether you’re buying a bare long block, a long block with basic ancillaries, or a complete engine with sensors and accessories. This article explores current market ranges, what influences price, and how to buy smart.
Understanding the market landscape
The 5.7-liter HEMI V8 is a long-running powerplant found in Ram pickups, Dodge Chargers and Challengers, and various SUVs. Prices for a used unit hinge on year and generation, mileage, wear on the valvetrain, whether the engine is sold as a bare block or with heads and necessary peripherals, and whether it comes with a warranty or return option. As with any used automotive component, demand can spike when a model remains popular and parts are scarce, nudging prices upward.
Pricing by configuration
To help buyers gauge what they’re shopping for, here are representative price bands you’ll commonly see, not guarantees. Keep in mind installation and incidental costs are not included.
- Bare engine block (long block only, no heads): $2,000–$4,000
- Long block with heads and essential timing components: $3,500–$6,000
- Complete engine with intake, sensors, fuel system components, and exhaust manifolds: $4,500–$7,500
- Remanufactured or rebuilt with warranty and full testing: $6,500–$9,500+
These ranges reflect typical listings from salvage yards, independent engine shops, and online marketplaces as of the mid-2020s. Exact pricing varies by year, mileage, included accessories, and seller location.
Where to shop for a used 5.7 HEMI
Potential buyers have several avenues, each with its own pros and cons. Shopping around and comparing warranties, return policies, and visible condition can save money and avoid surprises after installation.
- Salvage yards and auto recyclers offering used long blocks or complete engines
- Online marketplaces (e.g., eBay Motors, Facebook Marketplace, Craigslist) with seller history and buyer protections
- Engine remanufacturers or rebuild shops that offer tested units with warranties
- Local auto parts stores or dealership parts departments that sometimes source reman units
Across sources, you’ll find price variation tied to the engine’s condition, history (flood, collision, heavy use), and whether the unit comes with accessories or a warranty.
What to inspect before buying
Before committing, buyers should verify engine history, inspect for signs of overheating or prior damage, and confirm compatibility with their vehicle’s year and model. A few essential checks can prevent costly misfires or mismatches after installation.
- Verify year, model compatibility, and VIN-specific fitment for your vehicle
- Check for signs of overheating, corrosion, or coolant/oil contamination
- Ask for maintenance records, service history, and any known issues (e.g., timing set wear, lifter noise)
- Ensure a reasonable mileage range for the engine and confirm it has been run-tested or start-and-run tested
- Clarify included components (heads, intake, exhaust, sensors, accessories) and warranty details
Thorough due diligence helps ensure the engine you buy performs reliably and integrates with your vehicle’s systems.
Warranty and installation considerations
Warranty terms can vary widely. Some sellers offer limited warranties of 30–90 days on used engines, while remanufactured units may carry longer coverage (often 1 year or more). Installation costs, including labor, gasket kits, mounting hardware, and potential ECU or calibration work, should be factored into the total project budget. If you’re not a mechanic, consider a reputable shop that can confirm compatibility and provide warranty support for the installation.
Summary
The used market for the 5.7 HEMI is broad, with price bands that reflect the engine’s configuration, condition, and provenance. Bare blocks start in the low thousands, while fully equipped or remanufactured units with warranties can approach or exceed the mid-to-high four figures and beyond. Shoppers should compare sources, verify fitment, and get clear warranty terms before buying. With careful research, a used 5.7 HEMI can be a cost-effective way to restore power to a compatible vehicle while avoiding the expense of a brand-new engine.
