I have a complete londblock 6.0L engine valve covers to pan but it is taken apart.I was a core motor from a GM dealer and had nothing wrong with it but some carbon build up on the pistons.I took it apart and was going to change pistons and cam to make it a LQ9 and then i just bought a new truck and don't need it any more.Will take $500 for it.Billie 361-293-1574
