Default Lq9+243s in a RCSB

Ok guys so I picked up an 06 4.8l nv3500 5spd RCSB Silverado the other day to transplant my lq9 in.
I've purchased:
Stock 243s (should I go with tsp stage 1 or 2.5s instead?) 10.9 to 1 comp with stock gasket
228/232 .600 .600 112lsa cam
Ls7 lifters
Pac double springs
Chromoly pushrods
Ls2 timing chain
.040 cometic head gaskets 4.035 bore bumps it 11.3 to 1 I believe
Arp studs
Meiling high pressure oil pump
42lb drop in injectors
Gmt900/tbss intake and tb
Msd pro pack coils ls2/ls7 style I'll also be doing a coil power wire upgrade

Plan to purchase:
Speed engineering 1 3/4in long tubes and axle dump exhaust kit
Nitrous outlet plate kit to run a 150 wet shot


That being said I plan on swapping the nv3500 for a t56 magnum after I rip it out and doing gears at that time.

My only concern is I'm not going with a big enough cam. This isn't a daily driver this is a toy if anything. I have a diesel to haul with so I'll never tow with it.

What are guys running in manual RCSBs.

The cam is large enough to make some steam. Do you know the ICL?

It's a Torquer V2 but TSP doesn't have the cam specs on their site outside side of duration/lift/lsa.

I run an automatic so im sure it varies but, I run a 6.0 with ported 243 heads, tsp 228r 600/600 on a 110, nnbs intake with a 102 throttle body, longtubes and 4l80e automatic and run 7.60 to 7.65 on motor every pass down the 1/8th mile @4500lbs. That cam should work very well for you i would think.
