Nnbs intake swap question

[JakeO625]

The intake manifold is an upgrade. I have read about occasional failures with the xlink.

from the link already posted in this thread:

So for my 6.0 do I need an 07+ 5.3 or 6.0 intake or does it not matter?

Either will work. Can buy brand new for $100.

Awesome I appreciate all the responses guys. I'll update the post with pics whenever everything is installed.

Some miss info here.
Yes the nnbs intake is a upgrade similar to the trailblazer ss intake. Yes there good for about 20 hp and more if you have a power adder or supporting mods. That's pretty good Bolton. Injector rails needs to be custom on crossover or return systems. I would stick drive by cable with big throttle body. Be sure you have a intake that matches your cathedral heads. 6.0 nnbs has square heads. 5.3 is cathedral but same size intakes..

I sold my 6.2 heads and intake. Going with a custom blower intake.

So a tbss should match my 5.3 heads ?

Getting ready to do mine from what I've collected pretty straight forward all I have left to buy is the little eVap solenoid and the c5 filter

And im using the fuel rail and injectors that are already on the intake..

Is yours a 6.0 or 5.3?

So I can buy a 2007-up 6.0 intake for my '02 6.0 for $100 and swap it in and gain some hp? I have a BB autocal so I can have them tune for it.
