Build Core Engine – Specialty Engine Notice

This listing is for a Build Core Only, meaning this is not a ready-to-install engine. Because this is a specialty engine, we require a good, rebuildable core to serve as the foundation for remanufacturing.

A build core is a used engine that undergoes a complete remanufacturing process, including disassembly, inspection, machining, and rebuilding with new or refurbished components. The quality of the core directly impacts the final engine’s performance and reliability.

To ensure a successful rebuild, we need a complete, undamaged core with no excessive wear, cracks, or missing components. If you have any questions about core requirements, feel free to reach out before purchasing.

**We cannot ship your motor/transmission until we receive your core or the core charge payment.
