Lol, no we did not pull past 5500 (on another pull). Reason for this is I was more than happy with the numbers we had already achieved and did not want to push limits of stock block. My car is 90 percent street and occasional track so extracting every last bit of power was not of top importance. (Actually exceeded my expectations as it was) The dyno session was mostly for safe break in and tuning of Engine. We tried to simulate real street car testing using pump premium, safe timing, safe jetting, and water temp of 175. In this rpm range the hp gains per 100 rpm were greatly reduced. I suspect with agressive tuning and more rpm this engine would likely reach 575hp but for my application we didnt see the need to push it that far. My hope is that this engine will provide me with years of trouble free street service. Out of curiosity what rpm have your safely pulled an LA engine with hydraulic roller cam, I realize 5500 is well below the limits.
Next engine with r3 block will be a different story.
