Here you go, Piston area and force.

That only works if the induction system is able to simultaneously pass more air. And a big part of the increase is the larger Swept volume which increases the SCR.
What I mean is this, you can put a 5" piston on your pushmower, but good luck even starting it with that lil rope starter.. lol
This discussion is not including all that, but yet, taking for granted that the induction system can indeed handle any extra bore. In other words, we're basically talking about the short block.
