This engine was removed from a 2007 Chevrolet 6.0 aluminum vortex Max.  The engine had 153,000 miles when the DOD lifter # one cylinder collapsed.  I personally heard the engine ran prior to the engine being replaced. We gave the customer an option to replace the camshaft non DOD and get rid of the variable timing and reprogram the ECM. The customer decided to replace the engine with a new rebuild.. Of course it was an iron block and he didn't care. All exhaust valves are White except for cylinder 1 misfire exhaust. The engine spins freely prior to removing the timing chain and cylinder heads have not been removed to pull lifters and camshaft.. I obtained two of these engines now as I stripped the first purchase and ran out of shop space to strip the other one . Shipping... Will be free from dock to dock.. Please contact me with the zip code and City to ensure the closest trucking terminal.  I will provide a tracking number and estimate day of delivery. For home delivery it's just an additional amount due to not having a fork lift. I have shipped many differentials rebuilt so it's pretty easy. My shipping company works off quotes, therefore, it could be yellow, white, saia, Forward Air, UPS..
