Ross: can you find a dyno chart where you saw 328 hp and see how much power you have at 5200 rpm? It could be around 300 hp.

Either Hennessey modifies the kit in some way to cause less peak power, and a peak at 5200 rpm, or Hennessey is for some reason choosing to advertise power at 5200 rpm, rather than peak power at 6500 rpm. Either way, it's strange.
300 at 5200 is possible. Odd how they pick that spot to talk about.
