Ls6 Intake Swap - Will I Notice Difference??
I have a LS6 intake for my 98 Pace car. I was wondering if it is worth swapping now before I do my cam, heads and headers over the winter. I am wondering if my 1/4 mile times will improve? If they will only improve by a small persent or if that, I will not do the swap now.
What I have done to the Pace Car: Thermostat, reprogram, 3,600 converter, Factory 3:15 gears, after market mufflers and a Vara Ram. My best ET to date is 12.62 @ 108.91mph.
I understand that this is just an intake, But I am wondering if the stock intake is such a restriction that this wake it up or just a minor improvement.
Thanks,

Bah, it's super easy, just do it now and enjoy a few added ponies. You probably won't feel anything from that alone, but I personally can't leave a mod laying around and not put it on.

Thanks Guys, I think I will tackle this on Saturday. I never removed an intake on a Vette. It looks easy. I am actually (Dont Shoot Me) A FORD man.
I know FORDS inside and out and by looking at this intake, It appears to be a simple job.
I guess if I can swing an engine in an hour from my Mustang, An intake should be a joke.
I'll keep yo uposted to let you know how I made out. I see that there are rubber gaskets and no water jackets. At least I dont have to change the oil when I am completed.

The 2 back bolts you have to hold up and slide the intake forward alittle.I used a small vise grips to hold one up.The other one you can hold by hand.Piece a cake Rob ................Paul

Is there any way to tell if you have an LS6 manifold without removing it. Former owner is pretty sure that's what's on there, but not positive. I'm going to do some mods this winter and don't want to remove it if I don't have to.
thanks

No C5 intakes LS1 or LS6 had EGR. I'm sure someone can post the part # of the LS6 to tell for sure. If it has been swapped for an LS6 then the rear coolant passages on the heads will have plugs in them, rather than a tube to connect to the front coolant lines. Even if the plugs are in place, an LS1 intake could have been swapped back. The part # is the only sure indicator.

The pre'01 Vette had the LS1 intake and devloped 345 crank HP
The '01 and newer Vette had the LS6 intake AND a more slightly aggressive cam profileand produced 350 crank HP....
Explain how changing and LS1 to LS6 intake alone should generate 10 extra crank HP.

No... your stock tubes will work find if you grind down the ribs on the bottom of the LS6 intake, look and you will see what I mean.

You can tell an Ls1 from an LS6 intake by the casting mark on the 1st runner closest to the intake. If it is curved it is a LS6 and if it is a 90 degree angle it is a Ls1. I would look on a few 01+ cars to verify as I may have it backwards.
