what are the differences between the intakes? isnt the 6.0 a 87 or 90mm intake? what is my stock 5.3 intake, 78? would i see any benefits? my neighbor has one with injectors and TB and all ready to bolt in. if it is a 90mm i bet a BB tune would be in order?

 

its the exact same intake

 

doh!!

so what size are the TB? 78mm?

 

The TB is the exact same size. Not sure when they went to 87 but I thinks its 06.

They are 78mm
