I've got a stupid question about the Gen 3's: How come they don't seem to need the bigger duration like the older engine's do?



better port design....if you have a head that flows 320cfm with good port velocity and strong low lift flow, you don't need nearly as big of a cam as you do if you have a head that flows 220....
