Re: Which is Better....

Unless you're planning on running more than 8,000rpm all the time, the long stroke crank looks better. But there's not really enough information there - Is that just for a stroked crank and so more capacity engine, or, an engine with the same capacity and a smaller bore/bigger stroke?
If it's the stroked engine then it's no surprise that it'll make more power but if it's the same capacity then I'd be very dubious of that program - There's not a lot of difference (within limits) between a short stroke/big bore engine and a long stroke/small bore engine of the same capacity, all other things being equal. In practice though, the short stroke/big bore engine will always make more power as it'll have less internal frictional losses, less inertia, and the valves will be shrouded less.
