Look at the illustration of the 2013 cam. The exhaust valve is closed at 4 degrees past TDC. The inlet doesn't open until 12 degrees past TDC. There is no overlap. Compare that to the 2014 cam. The inlet valve opens 3 degrees before TDC. The exhaust valve closes 10 degrees past TDC, giving an overlapp of 13 degrees.
Forgive me alltohell if I am misreading that diagram, but that is what I see.

And I was at work today, thinking about this, when the revelation hit me....I bet he was talking about the 255, and not the 2013 cam!
My apologies!
However, in my defense, you "quoted" me....and the quote was on a reference I was making to the diagram!

Isn't there some text on the left side of this page from the Tech notes that references what this cam is close to?
Or maybe the page before or after. I could swear I saw text stating the new 2014 cam is "close" to something. Don't have access right now to the link.
