i am starting a similar build for my 72 nova now. going with that 223-231 cam, ls3 heads but ported truck intake. pat g has recommended the 223-231 113+4 and also the eps 226-234 113+4 so those were the cams i was searching for used and well i found me a 223-231. i say any one of those cams would be best with the 8 degree split to make up for the stock exhaust flow not able to keep up with the high intake flow. skeet has cnc'd heads and his exhaust flows better than ours so he can get away with less split duration. trucks are heavy and the torque numbers produced by the 223-231 you can see in the dyno graph would greatly help the heavy beast get a going and keep going... 
could catch!! and youre right

I ran a 227/239 115+3 .619/.629 cam with my 6.0 and LS3 heads...Great cam and pulled super strong. That LS7 intake manifold isnt going to work with the LS3/L92 heads nor will a LSXr manifold.

so after doing more research and planing... goes like this:
l92 heads milled .020 (I would like the compression 11-11.5 range) NA setup
I am going to get the FAST 102mm and TB 102mm truck intake.
The cam Im thinking due to the weight of my truck near 6000lbs a 223/230 Trucker V2 cam. 115 lsa? truck is heavy but I need lots of mid - top end with my 4000 stall and 4.88s.
Now I would like to know what type of HP increase I can accomplish with the above mods... maybe 75-100hp? I would like near 500 hp at crank.
right now my specs are in my sig. its a street truck build.

i dont think l92 heads milled .020 is gonna get you to 11:1. skeet ran heads milled .015 and .040 gaskets to get to 11:1. cam sounds good. what lift? 500hp at the crank should be easy with such combo.

"TR TRuTorq" Level 2 - 223/230 .609/.604 115 LSA
so that is what I came up with for a heavier truck like 5800lbs atleast. I do agree I will have to mill more to get up to 11:4.1 compression. Not sure if 30th thousandths would do that? I would love to have 500hp @ crank. Just need the right cam to do it with.

finally got me a cam speced. going with a custom grind. 227/239 .6xx with some cnced l92s and fast 102/102. This cam seems to match my gears/stall better as well. Im certain it should put down near 500rwhp.
