How does stroke increase HP ?

I'm not following you.....
I know there's a secret in your question; but I'm just not seeing it.

What would happen if you took all the 340 stuff and slapped it onto a 360, at same as 340 cylinder pressure?

Or how about a 383Magnum with a 440 crank?

or a 318 with a 4" arm
