I'm jealous, just bought a 5.2l but it turned out to be junk, now I'm gonna hold out for a 5.9.
Are you gonna run it as is, or do a refresh with new bearings and what not?
I may go as far as to pull the heads to look at the cylinders, and since i'll have the pan off I might pull a couple rod caps to inspect the bearings. But if it all looks good I'm going to run it as is.
