[QUOTE=BRAAP;508175]First off, thank you to all for your help in identifying this intake, that portion is closed. Now, is this Dorman intake an upgrade or not?

[QUOTE=BRAAP;508175]Now someone please take your 6.0L, optimize fueling and ignition timing, dyno it, swap intakes, optimize again and dyno again and let us know if indeed the DORMAN delivers.

Very infomative reply. My 6.0 probably wouldn't know the difference between the 2 manifolds but I would be curious as to the outcome of dyno tests between the 2.
