Which would be faster in THEORY???
If all 98-02 had the same capability given their factory parts, then upgrading the 98-00 cars with an LS6 intake, OR downgrading the 01-02 cars to an LS1 intake would yield in the 01-02 cars now being slower correct? That is, if your "noted" statement is what u said it is. So now it's contradicted.
What your reply basically implied was that whichever is fastest stock will be fastest even when they are all allied an LS6 intake. Now that will be true conditionally so long as its an 98-00 car, bc if the 01-02 car was fastest stock, and then the LS6 was added to the others, it would have the ability to no longer be the fastest meaning what you stated isn't only situationally correct.
I would have to say that the 2000 would have the slight advantage. Here's my reasons:
The 01/02 cam was much smaller than the 2000.
The 00 factory tune was slightly leaner than the 98/99, so with the added air flow of the LS6 intake, there might be an increase in power.
FWIW, I had a 2000 T/A that I added an LS6 intake to. No other mods other than the SLP lid. I routinely beat 01/02 stock T/A's by a car length or more. Now, maybe it was the driver mod
, but my 2000 was very fast. With just the intake and lid, it went 13.002 @109 with lousy 2.2 60 foot times.
So, there you go. I hope this helped.....

I personally do not think that the mild difference in the LS6 intake at stock power (air flow) is really very different. In addition, the difference in cams is very mild. GM may have changed them for whatever reason, but remember that 01+ is also shared with the truck motors and cost savings was a consideration to go alongside elimination of EGR.
FWIW I think these specs are the correct ones:
stock 98-00
duration@.050 198.86 intake 209.25 exhaust
lift .498 intake .497 exhaust
LSA 119.45
stock 01-02
duration@.050 196.37 intake 208.72 exhaust
lift .464 intake .479 exhaust
LSA 115.92
Corvettes have even more weird year to year variations.
As far as the LS6 cam, I have one in my car. Got it reasonably with a set of assembled 243 heads that someone took off his 03 Z06. It is certainly noticeable 3500RPM+. My trap speed went up 4mph from stock. Only you can answer if it is worth it, certainly an aftermarket cam can make a lot more power. The LS6 works with stock fuel system, idles more or less like stock, is easy on springs, and returns stock fuel economy. An EPS lobed cam may very well be in my future though, but not until I further optimize my times.
"If only I had an LS6 intake mine would be TEH FASTORZ!!1!11!"
No actually I don't have one at all, so nice leap there sir. Fail. Just trying to learn and develop a better understanding for all things.

I would say if everythign was exactly the same besides cam and heads between the years you have chosen i would say the edge is on the 2000, slightly better heads and bigger cam. IF everything was exactly the same besides heads and cam i think this is what you want to ask.
with an ls6 intake on the years you listed and nothing else done, I would say the 00-02's would be slightly quicker than the 98-99... the 00' has the bigger cam combined with the better 241 heads... but not all 00's had 241's, so thats hit or miss. the 01-02's have 241's and a smaller cam, but have better flowing exhaust manifolds than the 98-00'... So I would think that would make it a wash between 00-02's.
Well now it makes perfect sense. You want an answer, you need an answer, you know an answer exist if you just dig deep enough. Typical engineer IMO. The reason there IS NOT an answer is bc there are too many varibles along with negligible difference, you cannot pinpoint one solid correct or non-correct response. However, people like me enjoy watching you try. So carry on
Many things that I've researched and worked on are trivial like this, but it's just my nature and i figure if I bring up the discussion, I may learn more and others may learn something. Thanks all for contributing to this volatile subject
From everything i've read, there's virtually no real flow difference between any of the F-Body heads.
All else equal, the better cam cars might be a tad faster (virtual dead heat though).
FYI: The 01-02 cars had a cam with less duration and less lift so that GM could eliminate the EGR system...Not because the 01-02 heads flowed better.

Ha, that's pretty entertaining. I'm sure I could still learn a thing or two if I went back through high school, but I see it as a non point since apparently I was good enough to get through and become a Toyota dealership mechanic. Then I had the opportunity in front of me to go on up the chain there but after a good short run I decided I would try and go for a mechanical engineering degree in hopes of designing more logical and user friendly vehicles in the future.
I hope u enjoy your career and edumacation as well as current knowledge... I will continue to attempt to further mine and hopefully help others when I can unlike many on this site. I'm sure u have a vast abundance of information on these cars that I do not, so why not share or be helpful instead of try and belittle another forum member for wanting more depth. U could have just went on and not said anything, but obviously you have the time to waste so u can hangout and try and pick people apart bc they seem to care about something u think is irrelevant or not worthy.
I'm glad people in my field don't act this way when I bring up a discussion that is trivial and otherwise irrelevant to the real world. Thanks for the input tho

If this is the truth, then why do most guys consider a 241 head a slight advantage when adding a cam? I believe I've read before(back in the day when I first became a member) that a cam in a 241 head car would yield more potential power than an equivalent cam setup in the older head.
Just asking and trying to sound like I'm questioning the input.
I assume the better cat setup and lack of EGR also made the factory 241/LS6 cars quicker, so another discussion could be involve the addition of a longtube/!EGR + LS6 to the other cars. Then it would seem as tho the older cars would really wake up a bit(maybe even if only a fewhp difference).
Btw all, I am looking into buying an 01 car, but seriously, I have no agenda in this discussion, and am not looking to make or prove a point. I don't care how fast it is, but am intrigued by GM's minor changes.

GM's minor changes were for emissions and to raise the yearly power rating. As a platform gets older it's supposed to get more powerful you know. Its kind of a sales tactic considering we are actually only talking about peak numbers. On the subject of heads, I consider all LS1 heads equal in stock form. None yield an advantage or disadvantage as they came from GM. Whoever told you different is wrong.

All ls1 cars dyno right around 300rwh bone stock. Some lower, some higher. I have seen as high as 320rwh on a dyno jet from a 99 z28.
