Generation IV External Engine - lq9 with ls3 heads ls3 intake and g5x2 cam

Hey guys im building a lq9 with stock bottom end with ls3 heads and ls3 intake 42lb injectors with a g5x2 cam. Ive been told not to use this cam and ive been told to use it the cam what do you guys think?

.595/.608 232/240 on a 112 LSA,

I think it'll perform well, although LS3 heads tend to like a 12* split.

School me on this what's a 12* and the cam I have is on a 110lsa

well put it this way i have a nitrous cam for L92 heads in a big motor and its 25x/27x

most 6.0s i have seen use close to a 12* like stated above like 235/247 232/244 etc 12*

Oh I understand now thanks guys
