I don't think this will ever happen. Unless you substantially change the design of the new block to the extent that current speed equipment (heads, carbs, cams, and ignitions) will no longer fit, there will still be the same limitations of potential power output that exist with stock blocks. Sure, another 5 or 10% MAY be able to be picked up with better port design, larger bore, etc. but 300 hp (normally aspirated) will probably be still be out of reach for all but the very well heeled. The cost/benefit is just not there.

Plus, in the long term, I believe there is no shortage of good stock blocks. If the things I see posted on these forums are any indication, I'll bet there are thousands of guys out there that have multiple good blocks stashed away (I have four). I'm 74 and will never get around to using them. After my generation is gone in 10 to 20 years, there will probably be an oversupply.
