    I am curious because i put calipers on the xp cam and the exhaust lobe is like .529" iirc, and the stock cam is like just under .500" so how is the xp cam that much more aggresive if the lobe size are only about a .030" difference?

    Because stock cams are pretty peanut sized, think like .400"~

    IIRC they were like .411/.408 @ 115 LSA...so that's not really,
    just under .500"
    XP was .520/.536 @ 116 LSA, no?

    If the cam you took out of your car...measured close to an XP, well then it wasn't stock, lol.
