Just a thought, what do you think will make more power? A 302 Chevy with a 3" stroke and a 4" bore, or a 302 with a 3" bore and a 4" stroke? This example is a little extreme, but my moneys on the big bore short stroke combo. I could be wrong on this, but if I remember correctly, Nascar placed a limit on bore diameter several years ago as a way to limit horsepower. Bores were getting larger and strokes were getting shorter. Big bores, more room for bigger valves, and less shrouding equals more power.
