My ignorance is showing. Could someone please explain to me how boring and stroking (although stroking might make something bigger) a 3.2 could stretch it into a 3.8? I thought felix the cat was the only one who could grab a hold of something with a displacement (volume) of 3.2L and stretch its volume to 3.8L displacement. Is stroking a motor meaning to add bigger heads to make up for the .6L increase? Thanks for teaching this ole guy something today besides abstract cartoon physics.
