not very, can be fix, keep in mind that in a research article done by TDR, they found less then 1 percent of all 53 blocks cracked. only those who had a casting thickness of .254 or less. most castings they found were .256. This article was found in the April 2008 issue. My buddys 98 has almost 450k miles and not cracked yet, my truck has 240k and 450 hp and not cracked.
