Yep... oil flow and oil cooling are going to be critical to keep things running at these RPM's long term, above and beyond parts fatigue. I'd not approach this without forged bottom end parts, forged pistons, keeping the rotation weight down, etc. I'd also be moving to AL heads immediately, somply for the lower weight; weight loss (or moving it where you need it) in this application outstrips adding HP. So Summit employees et al are going to get their bonuses!
