I have a 2004 5.3l vortec with a 217/227 cam, I’m decided whether I should install a ls6 intake manifold or not, seen a lot of people say yes and no, as well will be tuning it if I decide to install, just need some feedback

 

Personally I'd stay with a truck intake, go with a NNBS intake if you want a minor upgrade over the NBS intake. But that does add a cost because of other parts needed to run it.
