It's quite simple really. If you want certainty that the 450 whp motor is gonna hold up, use an upgraded block - Dart, World Products, etc.
If you're willing to guess/hope/take some risk - use a stockblock or their clones.
What's happened to someone else's - good or bad - is simply not predictive of what's gonna happen with yours.
