Withinreason. The Main Webs can only handle so little hoop stress.
Whether you're clamping iron, steel, or diamond, I wolud stay close to the Factory TQ limit for factory blocks. Aftermarket block material MUST be better (higher tensile strength, probably same modulus) to warrant a high torqueset.
If not heeded, then my opinion is the crank will scrape the macadam at WOT.
