Alright, so you have 3 cars. All equal weight, drivetrain, options etc...

You have a 98, 00, and 02 LS1 car. All rock stock factory cars.

If you put an LS6 intake on each of them, which car would be faster???

Remember, theory here, so assumed base line horsepower numbers. No factory freaks.

98 had worst heads, biggest cam
99-00 had better heads, smaller cam
01-02 had best heads, smallest cam

Giving all an LS6 intake, what would happen? There has to be some sort of proportion that could be figured relating the head gains vs the cam gains, but I am unsure and figured id make a thread on it for some discussion So any input or "theory" is welcome, just make sure to at least say WHY you believe or know that b/c I want to learn and understand better and I'm sure other people do too

Well, if you were absolutely stock, the 01/02's already have the LS6 intake and better heads, which is why they put the smaller cam.

There were injector differences between the years too.

If an LS6 intake on each, whichever is fastest now would remain the fastest. Proportionally, there would be no change except for the car that already has an LS6 intake. If it had come stock w/ an Ls1 intake, what is noted would be true.

What transmissions and gear ratios are in each?

I'm not sure what you are getting at in relevance to my question. Given the LS6 intake on a 00 car and comparing it to a factory 2002(already has LS6 obviously) the results will not stay the same. The 00 is going to gain some HP with the LS6. It already has a bigger cam, but worse heads, so which will be faster?

Are the 241 heads a big enough difference to keep the 02 on top, or will the larger cam ofthe 00 overtake it?

they are all so damn close it would just depend on which car is running the best or has the best driver.

you also forged that the cars have different exhaust and cat setups.

Some if not most 2K model came w/ 241 heads just like the 01-02 model. Mine did.

I've been told it's not worth putting an LS6 cam in my car, so I figure the differences between the LS1 cams would also be negligible.

I did not know that. Thanks for mentioning it.

That's kind of what I was thinking... The cam size vs the head flow would probably balance them all out in power given they all had an LS6 intake. That's why I posted the thread, just to see if anyone else knew or had an opinion.

fbodies DIDNT come with LS6 cam just the intake from 01-02 cars

He never said any F bodys came from the factory with a LS6 cam, Just that the earlier F bodys came with a little larger cam than later ones.

Correct^

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.

In my experience the 01-02 cars are not faster than the 98-00 f bodies. The ls6 intake on a stock engine really isnt going to make a huge difference. Like someone else said the two biggest factors would be which car is running the best and the driver.

IMHO, I'd say...

any car driven by me, would be the fastest

I agree with this 100%. The mere fact that this subject is trying to be "dissected" and figured out by the OP is quite silly. The answer doesn't exist. Any further discussions pertaining to this subject is a waste of computing power of the intrawebzz.

Read it again. What is stated is that if the car that came w/ an LS6 intake had come w/ an LS1 intake, what I noted would be true.

Agreed, it's a pointless discussion.

Ha I'm sorry that my topic of discussion is not suitable for your noble needs. Next time I make a thread I will verify that u don't already know the answer. My attempt to better understand the top end of an LS1, while so feeble and welcoming to opinion was obviously not worthy of the Internet...

As I tuck my tail between my legs and walk away from the thread I will remember that learning and understanding aren't worth it.

Sorry, I will go back to engineering and unlearn every theory I've learned...
