I know a guy building circle track motors putting out 680HP and they are holding up good. He uses the high nickel 2 bolt main blocks and splays the other two bolts (studs) I have not heard him addressing any cracked webbing, but the high rpm circle track motor may not be experiencing as high a stress as the sprayed drag motor. I would get a few more race engine builders opinion before blowing of your block.
