How much does an LS engine cost? Depending on the engine type, condition, and what comes with it, a used LS engine can cost hundreds to several thousand dollars, while a rebuilt or new crate engine can cost considerably more. The right choice depends on your budget, the vehicle you are building, and how much work you want to do before installation.
Chevrolet’s LS engine family includes several generations and configurations, from common 4.8L and 5.3L truck engines to performance-oriented 6.0L and 6.2L engines. These options do not share one standard price. A basic truck engine pulled from a donor vehicle is a very different purchase from a complete LS3 crate engine or a professionally rebuilt performance setup.
Quick Answer: How Much Does an LS Engine Cost?
As broad U.S. budgeting estimates, an LS engine may fall into these price ranges:
- Used truck LS engine: Approximately $800–$2,500 for many common takeout engines, depending on condition and what is included.
- Used performance LS engine: Approximately $3,000–$7,000 or more for desirable engines and complete takeouts.
- Rebuilt or remanufactured LS engine: Roughly $3,500–$8,000 or more, depending on the rebuild, parts, and warranty.
- New LS crate engine: Commonly $7,000–$13,000 or more for many performance-oriented options, with specialized and high-output engines costing substantially more.
These are planning ranges, not live quotes or guaranteed market prices. Local supply, engine mileage, included accessories, shipping, and the seller’s warranty can change the final cost.
1. How Much Does a Used LS Engine Cost?
A used LS engine is often the most affordable starting point, especially if you are considering a truck-based engine for a project vehicle. Engines removed from Chevrolet Silverado and GMC Sierra trucks, along with other GM vehicles, can be available through salvage yards, engine recyclers, and specialist sellers.
The price depends on the specific engine code, mileage, operating history, and whether the engine has been tested.
Used 4.8L and 5.3L LS Engines
The 4.8L and 5.3L truck engines are popular choices for budget-conscious projects. Their availability in numerous GM trucks and SUVs makes them worth considering when comparing used-engine options.
A basic used engine may cost considerably less than a complete takeout assembly. Before comparing prices, confirm whether the listing includes the intake manifold, fuel injectors, throttle body, alternator, starter, exhaust manifolds, wiring harness, and engine control module.
An inexpensive engine that arrives without essential components may cost more to prepare than a better-equipped option.
Used 6.0L LS Engines
A 6.0L engine can command a higher price than a common 5.3L, particularly when the seller offers a tested engine with useful accessories or a documented operating history.
However, not every 6.0L is the same. Engine codes, block materials, internal components, and original applications differ. Identify the exact engine before paying a premium based only on displacement.
Used LS3 and Other Performance Engines
Performance-oriented engines such as the LS3 generally cost more than common truck takeouts. Demand, condition, and the availability of complete assemblies all affect pricing.
An LS3 listed as a bare engine should not be compared directly with a complete package that includes accessories, electronics, or other installation components. Check the included parts before deciding which listing offers better value.
2. How Much Does a Rebuilt LS Engine Cost?
A rebuilt LS engine generally costs more than a basic used engine because it has undergone some level of inspection, machining, repair, or parts replacement.
However, the word rebuilt does not guarantee that two engines have received the same work.
One seller may have replaced selected worn parts, while another may have had the block machined, inspected the crankshaft and connecting rods, installed new bearings and piston rings, and assembled the engine to documented specifications.
Before buying, ask for a written description of the work performed.
Important questions include:
- Was the engine completely disassembled and inspected?
- Was the cylinder block checked and machined where necessary?
- Were the cylinder heads inspected and serviced?
- Which internal parts were replaced?
- Were clearances and assembly specifications documented?
- Has the engine been run or tested after assembly?
- What warranty is included, and what conditions could void it?
A rebuilt engine with a clear parts list, documented machining, and a meaningful warranty may justify a higher price than an engine described only as “freshly rebuilt.”
3. How Much Does a New LS Crate Engine Cost?
A new LS crate engine is typically the more expensive option, but it can offer clearer specifications and a more predictable starting point for a build.
Chevrolet Performance offers LS and LSX engine families in several configurations, with different power ratings and intended uses. Availability and pricing depend on the specific model and package.
LS3 Crate Engines
The LS3 is a 6.2L aluminum-block performance engine associated with applications such as the Chevrolet Corvette and Camaro. It is also used in performance builds and engine swaps.
A new LS3-based engine may cost several thousand dollars more than a common used truck engine. The final price depends on whether the product is a long block, a more complete assembly, or a package with additional components.
LSX Crate Engines
LSX engines are designed for performance applications and can be built for demanding power goals. They are not directly comparable with ordinary used truck engines on price alone.
Block design, internal components, power capability, and the intended application can all affect the cost. Buyers should verify the exact model and specifications rather than assuming every LSX product has the same configuration.
What Does “Crate Engine” Mean?
A crate engine is supplied as an assembled engine rather than as a collection of loose parts. However, the term does not mean every component required for a running vehicle is included.
Some listings are long blocks, while others include more accessories or engine-management components. Always check the product description to determine what you are actually purchasing.
4. Used vs. Rebuilt vs. Crate LS Engines
| Engine type | Main advantage | Main consideration |
|---|---|---|
| Used engine | Lower initial purchase cost | Condition and remaining service life may be uncertain |
| Rebuilt engine | Work has been performed on the engine | Quality and extent of rebuilding vary |
| Remanufactured engine | May offer a defined restoration process and warranty | Confirm the remanufacturer’s standards and included parts |
| New crate engine | New assembly with published specifications | Higher upfront cost; installation components may be extra |
There is no universal winner. A used engine from a reputable seller with a documented test may be a sensible budget option. A properly rebuilt engine may suit a buyer who wants more assurance about internal condition. A new crate engine can make sense when predictable specifications and a defined warranty are priorities.
5. What Affects the Price of an LS Engine?
Engine code and displacement
A common 5.3L truck engine and a performance-oriented 6.2L engine are not interchangeable purchases. Identify the engine code and verify the specifications before comparing listings.
Condition and mileage
A running engine with documented mileage and test results may be worth more than an untested engine of unknown origin. Low mileage alone does not prove good condition, so ask what testing has been completed.
Included components
A complete takeout may include the intake, injectors, accessories, wiring harness, and control module. A bare engine may look cheaper but require additional purchases.
Warranty and seller support
A warranty can provide useful protection, but read the terms carefully. Check coverage duration, installation requirements, labor exclusions, return freight, and whether the engine must be installed by a qualified shop.
Shipping and handling
Engines are heavy freight items. Include shipping, liftgate service if needed, delivery access, and any core charge in your budget.
Vehicle compatibility
The cost of the engine itself is only part of the decision. Engine mounts, transmission compatibility, wiring, fuel delivery, cooling, exhaust, and accessory clearance can add to the total cost of an LS swap.
6. How Much Does an LS Swap Cost Beyond the Engine?
If you are buying an LS engine for a swap, do not budget for the engine alone.
Depending on the vehicle and the parts already available, additional costs may include:
- Engine mounts and installation hardware
- Transmission, adapter, or crossmember changes
- Engine wiring harness and control module
- Fuel-system components
- Radiator, cooling hoses, and fans
- Headers or exhaust modifications
- Accessory-drive components
- Driveshaft changes
- Installation labor, fluids, and troubleshooting
A project that uses a complete donor vehicle may be able to reuse more parts than one built from a bare engine. A custom installation in a vehicle that never came with an LS engine can require substantial fabrication and compatibility work.
For this reason, compare complete project budgets rather than choosing an engine solely because its advertised price is lower.
7. How to Buy an LS Engine Without Overpaying
Before committing to a purchase, use this checklist:
- Confirm the engine identity. Verify the engine code, displacement, model year where available, and key specifications.
- Clarify what is included. Request an itemized list of accessories, electronics, and other components.
- Ask about testing. Find out whether the engine has been run, compression-tested, leak-down-tested, or inspected. Not every test applies to every engine, so ask for the actual results.
- Review the warranty. Understand the coverage and any installation or break-in requirements.
- Calculate the delivered price. Add freight, core charges, taxes, and necessary missing parts.
- Check compatibility. Confirm that the engine works with your intended transmission, vehicle, electronics, and installation plan.
- Compare like with like. A bare long block, a complete takeout, and a crate-engine package should not be treated as equivalent products.
A seller who can explain the engine’s origin, condition, included components, and warranty clearly gives you a stronger basis for comparison than a listing that provides only a price and a horsepower claim.
Frequently Asked Questions
Is a 5.3 LS cheaper than a 6.0 LS?
A common used 5.3L truck engine is often less expensive than a comparable 6.0L engine. However, condition, engine code, included components, and local availability can reverse that comparison.
Is buying a used LS engine worth it?
It can be, particularly when the engine has a known history, useful test results, and the components needed for your project. An untested engine may carry more risk, so consider the potential cost of repairs before choosing the lowest-priced option.
Is a rebuilt LS engine better than a used one?
Not automatically. A rebuilt engine may offer greater confidence if the work was thorough and documented. The quality of the rebuild matters more than the label alone.
Why are LS3 engines more expensive than many 5.3L engines?
LS3 engines are performance-oriented 6.2L engines, while many 5.3L engines were produced for truck and SUV applications. Differences in demand, specifications, condition, and included parts can affect their prices.
Does a crate LS engine include everything needed for a swap?
Not necessarily. Some crate engines are supplied as long blocks, while other packages include more components. Check the exact contents and determine what else your vehicle needs before ordering.
Should I buy an engine and transmission together?
A matched engine-and-transmission package can simplify planning if the components suit your vehicle and power goals. Still, verify the transmission model, controller requirements, mounting arrangement, and included accessories before buying.
Final Thoughts
The cost of an LS engine depends on what you need: a low-cost used truck engine, a rebuilt assembly, or a new performance crate engine. The cheapest listing is not always the least expensive option once missing parts, shipping, testing, and installation work are included.
Identify the exact engine, compare the condition and components, and calculate the delivered cost before making a decision. For an LS swap, the best purchase is the engine that fits the vehicle, project budget, and intended use—not simply the one with the lowest advertised price.
