I'm not looking for peak hp and don't forget that an OEM ITR intake manifold does not fit a P72 head. I built this engine package to have the most power from mid-to-high RPM; not just at redline.
What is a higher peak HP going to get me? Nothing. You spend a fraction of a second at peak HP. However, every time I shift, I'm in the 5k-8k rpm range for 3-6 seconds. Where do you think the most torque and horsepower is needed?
