I was wondering why the displacement is different on the two supercharged versions?

very Interesting, the 6.4 bore to stroke ratio is almost square ... Is this why it makes more torque in ratio to HP?

Mine is on paper.. 410HP and 430'lbs .. but I know due to the cam,intake.. my torque comes in at lower rpm .. your cam in the scatpack is total different bring the HP out at higher.. only 10 in diff .. but the 6.2 has over 700 hp but only 650 torque.. that is where I'm wondering if bore n stroke come into play .. and to me this is important when building an engine for purposes
