224/224 vs. 224/228
All else being identical...what are the different characteristics of a cam with the same intake/exhaust duration versus a cam with an extra 4 degrees of exhaust duration? Both are very common, and I was just curious what the benefits of one are over the other.

A few years back, cam designers noticed that they could get more power by increasing just the exhaust duration. There was an article I read about it in last year, but I've long since forgotten where that was...as well as the "whys."

I had a 220/220 and there is hardly a difference in idle.
