This is a Chevy LS3 engine for sale in fairly used condition: a complete 6.2 litre aluminium small-block V8, pulled from a donor Corvette, Camaro SS, G8 GXP or Chevrolet SS, inspected, compression-tested and ready to ship worldwide. It works as a direct replacement or as the heart of an engine swap.
We confirm fitment from your VIN or project details and send photos of the actual engine before you pay.

Vehicles This Chevy LS3 Engine for Sale Fits
- 2008 to 2013 Chevrolet Corvette C6 (base models)
- 2010 to 2015 Chevrolet Camaro SS with manual transmission
- 2009 Pontiac G8 GXP
- 2014 to 2017 Chevrolet SS sedan

Automatic Camaro SS models use the L99, not the LS3. The L99 has cylinder deactivation and variable cam timing, so tell us which transmission you have. Corvette, Camaro and G8 engines also use different oil pans, accessory drives and exhaust manifolds, so we match those to your car.
Condition and Testing
Every Chevy LS3 engine for sale on this page is fairly used and tested. Before listing, we:
- Compression test all eight cylinders and leak-down any low readings
- Borescope the cylinder walls
- Inspect the oil for metal, especially rocker trunnion needle bearings
- Check for coolant contamination
- Look for leaks at the rear main, front cover and oil pan
- Turn the crank by hand to feel for binding
You get the results and photos of the exact engine with your quote.
Common LS3 Issues We Check For
The LS3 has a strong reputation, but a few things are worth knowing. Rocker arm trunnion bearings can wear on high-mileage or hard-driven engines, and many builders fit upgraded trunnions as cheap insurance. Engines that spent time at redline, or had a bigger cam on stock springs, can have valve spring problems. Some use a little oil through the PCV system on hard-driven cars. Rear main seals, pan gaskets and water pumps can leak with age. Most failed engines we see were over-revved on a missed shift or run low on oil on track, which is exactly what we look for when we test a Chevy LS3 engine for sale.
Do You Need a Replacement Engine?
A leaking seal, a tired water pump or worn trunnions are repairs. A spun bearing, a scored cylinder, a dropped valve or damage from oil starvation usually mean replacement, because aluminium block machine work and parts add up fast. A tested Chevy LS3 engine for sale is normally the cheaper, quicker option. Our replacement engine cost guide helps you compare.
Swapping an LS3
The LS3 is one of the most swapped engines in the world. It goes into classic Camaros and Chevelles, C10 trucks, Jeeps, Land Cruisers, Miatas, 240SXs and hot rods. Plan for engine management (factory computer and harness, a Chevrolet Performance controller kit, or a stand-alone ECU) plus a drive-by-wire pedal, a swap oil pan and mounts that suit your chassis, a fuel system that can deliver about 58 psi, and a radiator that can handle the heat. Tell us about your build and we’ll suggest the best Chevy LS3 engine for sale for it. Rules on swaps and emissions vary by country, so check what applies where you live.
Used vs New Crate Engine
A new LS3 crate engine is excellent, but it costs a lot more and still needs a controller kit for a swap. A fairly used Chevy LS3 engine for sale usually arrives with the intake, injectors and coils already fitted, has already run in a car, and leaves money for headers, cooling and wiring. For most builds and replacements, it’s the better value.
Why Buy This Chevy LS3 Engine for Sale
- Tested with real numbers for every cylinder
- Confirmed to be a genuine LS3, not an L99, L92 or LS2
- Photos of the actual engine
- A fraction of the cost of a new crate engine
- Written warranty
- Worldwide shipping with tracking
Install Advice
- Prime the oil system before the first start
- Replace the rear main seal while the engine is out
- Check the flywheel or flexplate and the pilot bearing on manual cars
- Bleed the cooling system carefully, because LS engines can trap air
- Make sure the computer and tune match the engine
Look after it and your Chevy LS3 engine for sale should give you a very long life.
