Question regarding a 6.0L intake manifold
I have 4.8L that I am removing, and replacing with a (408) 6.0L. My question is: Will I need to buy a O.E. 6.0L intake manifold or is my intake thats on the 4.8L the same. If not does anyone recommend an aftermarket intake, except the LSX, I heard they take alot of modifications to get them to fit. I am also planning on using the factory 8.1L injectors. I appreciate any info on this................

All the truck intakes are the same. The only difference is some of the older trucks had EGR and the newer ones don't so there is no provision for it on the newer intakes. Other than that they are the same though. 
The injectors will fit fine and only require some tweaking of the IFR table in the computer to get them to work right.
Sounds like a nice truck you got, keep us posted on how it turns out.

My 2000 Sierra has EGR for sure.
