You will notice an improvement in flow--but I would go with a ported TB to go along. You may also need to upgrade your injector size--what is your duty cycle now at WOT? You will need to relocate your accessories since the intake has a lower profile than the truck one--but it sounds like you've got that covered. Have you taken it out to look at it and to compare all of the barbs and fittings? Will everything from your truck intake plug into the LS6 intake?

And yes silly--we can do the install. You name the time and place.
