Whatever it makes, I expect it's going to be at well over 7000 RPM and will require around a 6K converter and plenty of gear to keep the RPM up down track.

My RB 452 has standard port Victors and a 265 at .050 roller; peak HP 6900 and peak torque 5100. Even though you have 3 points more compression, the bigger ports and much bigger cam are going to shift your peak RPM #s up way higher than mine.
