Headed to the Dyno. Any guesses?

As I said earlier, we have a very close motor. Really close to the same. You have more compression and a little more go fast toys, so I expected us to be close but figured you to have 40 - 50hp more than I have. With everything in my motor I wanted more as well, but 500hp is a lot to get out of a sb without serious cash outlay. Here is what I got.
