Oregon Cam #346 - questions

Also like @RustyRatRod said 210HP out of the /6 is not easy. You saw in my models these class cams that I am talking about are in the 125HP range but the torque is up there. To push that 200HP boundary you need air flow and a cam that breaths at high RPM. With the bigger valves you maybe able to get there but look at those graphs. If you extend the RPM range and get those big HP number look how fast the low end torque comes down when you do that. You need to choose do you what HP at 5500 RPM or Torque at 2500 RPM. You can't really have both (you can but it becomes a "there is no replacement for displacement" argument).
