What all do you need? just block and crank? I have a 6.0 complete that was in a truck that caught fire. The balancer and timing cover are in sad shape as the truck hit a tree, but the rest should be just fine. PM me if interested.
I have a 6.0 Lq4 that I used for mock up in my chevelle project. It has no oil pan, intake or throttle body but the rest is there. Not sure of mileage or internal condition but the heads, crank, and block should be good for a complete rebuilt. Located in south florida.
