When you're buying an engine, you want something that's tested, reliable, and ready to go. That's what you're getting here:

Fully Tested: Every engine I sell has been compression tested, checked for oil pressure, and run at operating temperature to ensure you won’t run into any surprises after installation.

Complete Package: It’s a long block, which means all the core components are included. No hunting around for separate parts.

1-Year Warranty: You get peace of mind with a full 1-year manufacturer warranty, so if there’s any issue with the engine, you’re covered.

OEM Quality: This isn’t a rebuild or aftermarket part. It’s an OEM engine, so you can trust it’ll fit and perform just like the original.
Shipping can be arranged to either a business or residential address. If you’re having the engine shipped to a residential location, just note that there may be an extra charge. Once it arrives, we recommend inspecting the shipment thoroughly before signing off, especially if there's visible damage. If anything looks out of place, make sure it’s documented.
When it comes to installation, you may need to transfer over some of your existing accessories like the manifolds.

This is standard with most engine swaps, so your mechanic will know what to do.
For any questions regarding compatibility or shipping details, please feel free to reach out! Ensure this engine fits your vehicle by verifying the VIN and specific requirements before purchase
