Are 7.3 blocks THAT prone to cracking?

I know that the 96's had a short rash of blocks cracking which were often stitched by Navistar under warranty. I've also read a few threads about blocks from about 12/97 to 2001 cracking along the freeze plugs. Well, all this has me paranoid....just looking for your guys opinions on this.

I personally have never heard of anyone around here with a cracked block. All I generally here is that the 7.3 lasts as long as the 6BT (53 block being the exception) when stock or very mildly tuned.

You have a better chance of being struck by lightning or winning the lottery then getting a cracked block. Run the #### out of it and enjoy.

Best advice I have seen on here "If you cant afford to build it right you certainly cant afford to build it twice"

The only ones I've heard of were the short run of 96's (and that was a factory defect). If you don't have one of those, I wouldn't worry about it (and if you did and it was fixed by IH, I wouldn't worry either). Cheers!
