bore x stroke
<div class="FTQUOTE"><begin quote>Originally posted by: Freaksh0w
That is QUITE the difference in stroke. The bore doesn't mean much, but stroke goes a long way. It gives more leverage on the crank. And there's nearly a half inch difference between the stroke on those two. Just like a 302 and 351w, a 302 is 4inx3in and a 351w is 4inx3.5in. Lots more torque down low.
Yes, other things come into play, but the 302 is a rev king and the 351w is a torque monster.</end quote></div>
I agree with you but lets put down numbers...
lets say you got a 302ci with 300ft/lb and gain 10% by ading .5 inch of stoke (only hypothétical), your gain is 30ft/lb which is quite noticable.
Now on a 10% increase in torque on a 20ft/lb engine -> only 2ft/lb of gain which I seriously doubt will be noticable and can be compensated with a very small gear ratio adjustment. maybe an experienced driver could fell it ¿
