You're an idiot for even contemplating that cam, use this one instead

What LSA, ICL/ECL combo to use with this cam? first off the setup basics
Trick Flow 215's out of the box
hoping to use .040 gaskets might have to settle for thicker
Fast 90 out of box
QTP 1 7/8 race headers with HVMC
3" off road QTP Y pipe with the 4" flowmaster collector
exits out a 4" Borla XR1 that dumps before the axle
Coan TH350 RMVB w/ brake
ATI 8" treemaster MRT with current heads/cam it stalls to 4600
4.30 gear
27" ET radials for the footbrake, 28x9 MT slicks for the tb
the cam i'm looking to use is the SI7 cam from Speed. its a 238/244 .605/.612 on XER lobes. it comes standard 110 +2.
I'm set that I want the ICL at 108, but am undetermined to where I want the LSA to manipulate overlap.
so I basically want your guys opinions to see if I should do the SI7 as standard (110+2), 112+4, or 108+0?
also how will the ECL's that come with the 108 ICL effect the combo?
thanks,
Steve

With the strong exh flow #'s that those heads have I would suggest a single pattern cam instead. Something along the lines of this cam:
Adv Duration 278/278
@0.050" Dur 240/240
Lift .617"/.617"
111 LSA
107 ICL
Adv Duration 278/278
@0.050" Dur 240/240
Lift .617"/.617"
111 LSA
107 ICL

I like the SI7..
overlap is most balanced around TDC, and I know low end torque is not your biggest concern so I don't see the need for delaying EVO with the widest of the LSA's. LS motors are pretty good compression and you are probably bumping yours.. and that like a slightly wider LSA. I like the 110+2.
