Not new but new here...6.0 build list
 

Below is my build I'm currently working on and have MOST of the mentioned parts from my previous trucks. Anyone see any issues, have any advice or imput?
I've contacted several people about cam selection and have decided to go with a Tick performance sns or BTR ls3 stage 2.... pretty close to each other.
I'm guessing around 425hp to the wheels on motor alone?

Skip all the FAST parts, really just skip them.

The FAST intake is not worth the power to dollar ratio and will not be something you'll see an real gain from. Over $1500 with intake/TB/rails/Injectors to gain very little power over other parts that you can buy.

The TBSS/NBSS intake is far cheaper and still has gains over the NBS intake manifold. Stock truck rails will flow more fuel that you will need and FAST injectors I've heard have bad injector data or no solid data at all.

You only need around 40lb/hr injectors to reach a power goal of 400-450 on pump gas, there are several stock GM injectors that flow that much.

I know the fast set up is not the best bang for the buck. However, I had it sitting in the garage ready to go minus the tb.

If you can find someone that can tune the intake, I say run it. On a stock engine, the gains aren't worth the money. The tbss intake was a restriction for my lq9 after I got the afrs on.

Unless you already have the 1-7/8 headers, save money and get some 1-3/4s.

even if you have the walbro 255, I'd probably get a 450 to run instead. They are cheap. And you won't have to swap again for future mods.

425 rwhp before the o shit spray isn't an unrealistic goal. The 4.10s will eat some power.
