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.

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.
