Couple points to make here, I have said on more than one occasion that they SEEM to make good power. Perhaps you haven't seen me say that. The whole issue is there are only a few cars even running the bloomers, so it's hard to get an accurate comparison to what's out there. I form my opinions from EXPERIENCE, not from 3 cars and 2 guys on a car forum. Also, just a FYI, John was running 9s with his smallblocks 20+ years ago, that's common knowledge. With that being said, we will be testing various SBM heads on the dyno in the near future, and if the bloomers make more power, they will prove it for themselves. And I'll be more than happy to let everyone know how they perform. None of that is "hate"
