You being the big gas man and know all there is to know, what does the valves start floating at on this nine liter motor? Fact is what I want. Do you actually know what valve springs it has on it? I do know that a small block 350 will turn 7500 with stock valve springs without floating them. A LS1 will also turn over 7000 on stock valve springs without floating them. When floating the valves the motor will begin to miss and will not gain anymore rpms but will not necessarily "self destruct".
With the stroke being smaller than the bore the motor it is capable of making more hp than torque. The numbers that you posted of the torque then they have the rpms dialed back for reliability.
As far as the "little 5.9" goes. This 5.9 Cummins turns 5000 rpms on the track.;)
