Here we have a good used and running well complete 6.6 LBZ Duramax engine assembly removed from a 2007 GMC 2500hd. This is being sold as a complete engine with all accessories and fuel system but WITHOUT any electrical. 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. Please review all of the photos and video as youll see how well this engine runs and also that the injector balance rates are all in spec.
