Ok so I have a 2008 Chevy silverado crew cab with these mods
Cam, headers, AFE CAI, 3000 circle d stall, tune, and 373's
I'm putting down 360 horse to the wheels how much more will a fast lsxrt intake with a NW 102 give me with this setup? Would it be worth buying it?

What cam do u running if I can ask nice numbers you got there this is a dyno tune or mail when if I can ask what exhaust system you got

I would think there is a lot more to gain from ported heads at a very similar price point to the FAST and 102 TB.

Those mods are worth power for sure... but it is very dependent on the cam. If you have a smaller cam that doesn't rev very high then the gains wont be as large as if you have a big one and rev it out to 6800 RPM.

It's custom grind comp cam 230/230 4inch exhaust and chuck tune

But wouldn't it be better to get the fast intake then port heads?

Jesus.. big 5.3 cam. Yea with a cam that big on a 5.3 you will see gains from the intake. What RPM is your peak HP at currently?

1,300 for a budget head gets you 30-40 HP. (including gaskets/bolts/fluid etc)
1,500 for a 6.0 gets you 60-70 HP.

math says get a 6.0 IMO.
