Here we have a good used complete 6.6 LLY Duramax engine assembly removed from a 2005 GMC 2500hd. This is being sold as a complete engine with all accessories and fuel injectors, cp3 etc but WITHOUT any electrical. As you can see in the video the engine runs great and the last pictures show the balance rates are good. 60 day warranty covers the long block components only, does not cover any serviceable bolt on items which can be swapped from your core engine that we dont need back.
