If your going to the trouble of changing the intake, why LS6? I'd go perhaps F.A.S.T, or depending on funds a larger F.A.S.T with a new TB.
Also don't forget, when changing from an LS1 intake, you will need to change the coolant lines under the intake, as the LS6 and F.A.S.T are deeper, not leaving any room for the coolant lines. I believe you have to change the valley cover screws too. A guide to this mod can be found here:- http://www.ls1howto.com/index.php?article=5

If you get an ls6 you can get a grinder or pliers and knock the tabs under the intake to make em fit without having to change the lines, either way there is lots of information in the search feature!

I noticed some torque, with just bolt ons. Dont let the coolent pipes worry you about the swap new one s are cheap,but if you have grand sitting around do a FAST 90/90 or just stick to a P&P TB and ls6 its going to be good for what you have and cam.

well ur username is fast99formula so ill guess that u have a 99 formula, i believe that 98-00 came with the ls1 intake and 01-02 with the ls6, so u might have the ls1 unless it has already been swaped out
^^^ that's something to look out for if you buy used. vettes didn't have EGR so sometimes people try to pass off those intakes as ls6's.
i have a ls6 intake and ported ls1 tb on my 00 C5 that i upgraded from my ls1 intake that i am looking to part with since i just bought a fast 90 intake today.
pm me if you are interested.
