    The second cam is going to be easier on the valvetrain.
    Anyways, figure out what sound you want, and what goals you have. IMO the ASA cam was a nice cam. cost effective horsepower. And could run just as long as a stock setup. If you going to DD it, I would suggest a lazy lobe, and lower lift. If its a track truck, and your not going to put 12kplus miles on it, go more aggresive.
    well that also goes back to what lobes its on. you can have 2 cams with similar specs but totally different lobes.

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    OK funny guy. the 2 cams I mentioned are identical, minus the lift.

    Yup. Like Comp's XER, XFI, and XE. They all could be the same lift...but the lobe design counts too!

    And that's why I got the XERs!!

    you can also have mixed lobes. the more aggressive the lobe the less life of springs.

    A .000"/.000" 000 @ .050" with a 0 LSA is easiest on the valve springs.
