Stroking theory question

Main reason for stroker engines is as people want more and more N/A HP you' ll need to do it through combination of Rpm and displacement. And there's a limit to how much rpm that is practical for any giving application so displacement is the more practical. The most power will be made with over square engines with proper rod ratios but in reality you can only go so large with bore size so square or under square engines is the only practical way of getting large displacement.
