Another bonus of a longer stroke, besides greater displacement, is basically increasing the leverage of the crank...Kinda like when you take off a rusty bolt, it takes less effort to remove that bolt with a longer wrench (why cheater bars work ect.) In an engine, what that amounts to is greater torque at lower rpms. As with everything there's a tradeoff, in the form of higher piston speed at any given RPM = higher friction, and greater centrifugal stress on the crank at any given RPM = broken crank at high revs...
In general terms, if you want a low/mid range high torque engine go for a big stoke. If you want a high revver, keep your stroke within limits of say a 350 cid stroke. If you want both...prepare to pay for forged billet stuff in your short block.
