I am going to guess that 700 is pretty optimistic for a hydraulic cammed 440 unless you are into power adders. It would take compression and great heads to get close and even then I don't think it would be attainable. I know nothing about Gen III stuff , so I'll leave that one to those who do. I might be close with my 405.....I'll find out soon enough. But that is a solid roller , W-9's and 12-1.
