It doesn't mean it will crack. Just saying that it can crack.

The worst years were basically 1997 and 1998. During 97/98 about 1/3 were affected.

Each engine does have a casting number, if you read up on Chuck's site he'll have listed the old casting numbers and new numbers.

30k is not the end-all number, merely a guide. I'm sure there were more than a few that cracked above 30k, but it seems that most that cracked, cracked with less than 30k.

If the VIN has a Z as the 4th character, you may have a flawed engine. The updated blocks with F as the 4th character came out in late 2001.

6.5L N/A engines didn't seem to have this problem, those have a Y as the 4th digit of their VIN.
