Build Core Required

This product is a Build Core Engine. It is not a ready-to-install unit. You must send in a good, rebuildable core for us to complete your engine.

We fully remanufacture your core with new or reconditioned components. The engine is disassembled, cleaned, inspected, machined, and rebuilt to our rigorous standards. Please ensure your core is complete and free from cracks, heavy scoring, or missing internals. For questions about acceptable cores, see details here.
