Very cool. I'm in the planning stages of "engine no. 2" and want revs more than bottom end torque (what I built mine for). I want to turn 7K and figured I can't with hydraulic lifters. I actually want 7500+ RPM and figure I will be running a solid roller cam.
I'm curious to hear how your motor runs at those revs, should be very sweet. I know the difference on mine between 6K and 6300 sounds amazing. I start floating a little bit (I think) at 6300. I'm going to put the 6500 "pill" in the MSD box and see.
I'm running a tad more lift than you (.580") and a little less duration (240 at .050") and there is a noticeable difference in sound from the FMS 392. Also running more compression (10.25:1) than the crate 392.
Similar animals, yours is just on more drugs. In this case, drugs are OK.
PS... Good choice on 408 vs. 418. Personally, I don't like to go past square on the bore vs. stroke. That opinion may have no merits, but hey... most of mine don't!!
