The XP is a nice and proven cam I will agree. Ive also seen great results with the 1X. I like the fact that the 1X isnt bleeding off boost like the XP and you dont need to run a 3.0/2.8 pulley to see the same boost as a 1X with a 3.1/3.0. Shit, Merc ran 12.1 non ICed stock heads, Randy Major ran 12.4 non ICed stock heads, and FastGS ran 11.9 ICed with a 1X. Once the tune is down, I think a G5 ICed 1X with short ass gears will rip it pretty nicely.
