Most of that can be attributed to the heads and the ability to run a pretty healthy cam.

Are those numbers Gasoline?
Not sure if this is in a boat running Nitro or if this is another project running gasoline? Or is it common to run Gasoline on the dyno and save the expense of running Nitro.
Well I assume top fuel in boats is Nitro. I have watched it on TV from time to time, but not payed it too much attention. For that matter I don't follow drag racing or Nascar either. I enjoy them all, when I'm at a track, not so much on TV.
