I wouldn't say you offended anybody. Just several think big HP in a stock block is a bad idea, or a hope and pray situation at best (me included) and were offering up those opinions. Others look at these threads for guidance as well, so the information would also be for people other than you. Like has already been said, if YOU are comfortable with what you are doing and willing to take the risks, that's fine. It's your money, your time, your car. Others were only offering opinions based on their own experiences. I know myself, I have seen cracked main webs in numerous stock RB and B blocks. Some with LOTS of cap chatter marks, and some with none, so don't limit your inspection to cap mating surfaces only
