IMO it's not a common problem at all considering all the LS7's on the road today. Something can always go wrong with ANY engine with the production numbers of the LS7. It is a stout engine, just follow the recommended maintenance on it by the book.
Having said that, if it is a crate engine, it is a small amount of work to check the bottom end just for peace of mind.
