5.3 vs 6.0 intake manifold?

[mean05]

Did you use your stock fuel rail or have to use one that came with the intake?
If your 05-rail worked the 99-03 rail should fit too.

i have a 03...i modified the crossover rail and kept my return style rails, but going back on it and doing it over again i think i would have found a better way and used the returnless style rail that comes on the 90mm intake. Now i have gone over to a LS2 intake with some aeromotive rails...10x cleaner install
