Re: want NOS on 5.3 help If you want to go dry you can do the cheap route with a NOS 5177 kit, that is what most the fbody's use.
If you go wet I would with TNT or NX. I have a NX 100 shot on my car and it works very well, kit is very nice. The TNT kits have been known to make HP than the other kits. The average TNT 100HP shot usually puts down 110-120. The average NX 100 shot usually puts down 100hp.
Im not sure what the fuel system can support on those trucks, I know on ls1 100-125 is pretty safe with a wet, even 150 if you are monitoring some different parameters like knock, timing and 02 voltages to see if your lean.
Good Luck.
