Also, at what point does the stroke shove the piston into the cylinder wall instead of up the wall?

I would guess for any given bore size and rpm ain't really a factor like 9-12 thousands rpms is no big deal I'm sure there's will be a point were the increase frictional hp loss will cost more than any displacement of air gain through stroke where that is?

I remember an 413/426 Max Wedge super stock racer said Chrysler found 92% Bore stroke ratio to be the ideal power/friction compromise, that was over 30 years ago I read that and based on IDK :)
