Buying used gmc engines
A used engine is an original factory (OEM) engine removed from a donor vehicle, then inspected and tested so it can be installed in another vehicle with the same engine. It usually costs far less than a new or remanufactured engine. The key to a good purchase is a confirmed engine code match, known mileage, a test record and a written warranty.
Used engines are typically sold as a long block or as a complete assembly with the intake and some accessories. Your quote states exactly what is attached, such as the intake manifold, exhaust manifolds, sensors, alternator or starter, so you know what to transfer from your old engine.
