Build Core Notice:

NOTE: THIS IS A BUILD CORE ONLY ENGINE.

This listing is for a build core engine, which means we require your old, rebuildable core to serve as the foundation for your new engine. 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.
