Build Core Engine – Important Information

This listing is for a Build Core Engine. It is not a ready-to-install unit. We require a good, rebuildable core to serve as the foundation for this remanufacturing process.

A build core undergoes disassembly, inspection, machining, and reassembly with new or refurbished parts. The condition of your core directly impacts the quality of the final engine.

We ask that cores be complete and free from excessive wear, cracks, or missing parts. If you are unsure whether your engine qualifies, contact our team before placing an order. You can also review additional details in our Help Center for shipping procedures.
