232/232 .595/.595 110+3 is the cam i specd out for my self based on ve's and shift points of 6500-6600 rpms its not a DD. the car might get a 100-150 dry shot of n20 next year, and im not 100% sure it will.
with the mods that i have. lid, p&p Tb, ls6 intake, edelbrock 1 3/4 stepped to 1 7/8 long tubes, ory and slp lm II. would the 232/232 work or should i add 2* to the intake or exhaust 234/232 or 234/232

Sorry, I was useing Erson Cams .355" lobes for my reccomendation. The lobes are 296/292 Adv. duration, 236/232 @ 0.050" duration, .603"/.603" lift, and you would have your IVC at 42*. You would also still have 8* of overlap @0.050" duration and 68* of overlap @ Adv. duration.

on all stock stuff I'd bump the duration down on both sides... you'd make more power under the curve and your tq numbers would be nice all the way up...
I'd do something like a 233/228 .596/.581 110+4
you would like that cam, and if you wanted to spin it up to 6500, it would still make good power. The cam you have in there now isnt huge but if you bak it down a couple degrees, it make the feeling of needing more exhaust duration go away, and give you a ton of low-mid range... I ended up with my 5.3's grind after many nights of math and studying dyno sheets, its just what you have to do. I run a 224/227 .576/.588 113+3 with a 150 shot.

With the lobes that he has picked out there is no need to run a 1.8 ratio rocker on the exhaust side, he has pleanty of lift. The exhaust side responds better to duration, not lift, your intake valve responds better to lift however.

Pat G and Pred Z have helped me. I wanted more mid top end power that still had some low end left in it. I wanted 6500-6600 rpm shifts that's the reason for the 232/232 on a light lsa/icl good lobes and VE's and the lower lsa/icl will bring on the power sooner, and should be great to shift at 6500. But for a 100-150 dry shot from that new NX kit will I be choking my motor with the extra N20? btw the tsp torquer v2 on a 112 will pull to about 7k but if the lsa and icl are lower so will the powerband
