I started putting away money for a Cam in a few months amongst a few other mods like a GenV. So far I have a top-swapped GT with SLP Headers, 3.2 pulley and a S2IC. I'm torn between the VS, which apparently is great with an IC and stock heads, or the XP cam which is more aggressive but requires springs and other stuff. I don't mine spend the extra for valvetrain upgrades for the more aggressive XP, but still wouldn't mind saving the money and going with the VS cam. Some friends have said "you'll be happy with the XP and glad I spent the extra $ and did the extra work, then others say "you'll be fine with the VS. Has anyone tried them both? XP or VS?
