Build Core Engine – Important Notice

This product is sold as a Build Core Engine. It is not a ready-to-install unit. We require a good, rebuildable core to remanufacture your engine to our standards. During the process, we fully disassemble, machine, and rebuild with premium or remanufactured parts. The condition of your core determines the end result.

Cores must be complete and free of major cracks, missing parts, or extreme wear. For details, visit our Help Center or contact our team.
