My engine build has been on hold due to unforseen costs associated with hidden uni-body damage. I don't have any functional results yet. Hope to make some progress next spring. He has an online quoting tool where you feed him your specs and application and he will give his recommendation. I plan on calling and speaking directly with him before I order, but from what I've gathered his recommendation should be about as aggressive as I'm going to want to go and keep some level of street manners. I specifically asked for something that has good mid-range torque for powering out of the corners, so my guess is it won't all be at the top end. I think I gave him a 6000-6500rpm for max HP and 7000 redline.
