Well actually, in reality, they had to make some changes to justify the rated power increases. There would need to be hardware changes needed when people ask what they did different to make the extra power. The LS6 intake was one of these milestone changes that allowed GM to justify the power rating increases.

But they also used a smaller cam when they added the LS6 intake.... so does it still justify the power rating increase. I actually have a different theory why they added the parts. I think it just made everything more streamline and cost effective. Look at some of the other changes LS6 oil pump, LS6 clutch, ect... Not having to have to make so many different parts and still keep the cost down. IMO

Yep, my previous 2000 T/A dyno'd 316 with only a Flowmaster catback, universally derided as the worst catback for our cars.

FST SS

I think the Pewter one would be faster.

My 02 LE SS put down 316.7 on the dyno at the tires bone stock with a SLP LID and Blackwing filter. After installing the 1 3/4 inch Ceramic Hooker LTs , TSP 3 inch catted y-pipe, 3 inch I-pipe, 3inch over the axle pipe, Hooker aerochamber 3 inch to 2 2 12 inch outlets and CME with a smooth Bellows and Dynotune it made 341.6 at the tires.


Needs a Convertor and a camshaft. I thought about putting a LS6 cam in it but everybody says u can get alot more out of it with the aftermarket cams.

I have never seen any proof the fm robs horsepower on a bolt on car. Good numbers for sure.

The smaller cam was not enough to out weigh the gain of the ls6 intake... also the 01-02 cars got the better flowing ls6 exhaust manifolds.

The 98 cars. It really comes down to the driver,weather, state of tune ETC. What color they are painted and so on. Wheel and tire size, options which equal weight.

But the internet says it's terrible!! I'm sure there's Wiki page explaining the flow actually goes back to the engine when you use a Flowmaster catback!!

You mean slow master mufflers are good for making power. What color do they come in.

I would like to see the "best" camshaft with the LS6 intake w/ the best exhaust manifolds on an intake on a LS engine would make. "Best" means different things to different people.

People need to stop thinking everything they read on here is the gospel.

i.e. Flowmasters.

Footlead try a 02 Ls6 cam it would make decent power. They do on the trucks. Everyone will tell you that its not worth it. I installed an 01 and it made some top end power. The 02 has more lift. They run and sound like stock it should be good for 20-30 hp.

Ive heard 20-30 with that camshaft. If Im gonna do a cam and all the work that goes with that the net warriors say buy aftermarket cuz they will make alot more power than the 02 Z06 camshaft. I guess its preference and how much money you want to spend and how much worse you want your fuel economy to be. The Z06 wouldnt make much difference in economy and it would sound bone stock..whereas when u put a sweet hitting camshaft in her they will hear you coming.. burn more fuel ..stealth??or not...fast??,,faster or not.

My car is n0t a race car for sure. and I love to jump in it and cruise to Galveston or Austin with no worries or problems. Decisions decisions

You could always put in a two piece timing cover (Edelbrocks are pretty inexpensive compared to the others) and if you decide to change things out later on, it would be a little bit less work.

I concur with everyone else. The differences would be so negligible that it wouldn't matter.

On a side note, if the majority of LS1 f-bods put down about 300rwhp, or about 350 at the fly, and the Z06 has about 405 at the fly, is it safe to say that adding an LS6 cam and 243 heads will net you roughly 50hp?

The 00 exhaust manifolds are the same improved design as the 01-02; the only difference is that they have provision for EGR.

You can't go wrong with GM parts. Install the 02 LS6 cam and springs and it will last for 100k miles. A 3000 stall with lock up and you will be good to go. Then a small N2O shot.

I think a better way to ask this question would be to say, on an engine dyno which one would be highest. That would be the most accurate result, independant of all of the other attributes of the car, since you only seem to be concerned with GM's changes to the motor itself and not the rest of the car. Same LS6 intake, same weather, same day. In this scenario my money is on either A) 98 motor or B) an 01-02 that had the LS6 block, due to the better bay to bay breathing probably making it slightly more efficient (I've seen stupider ideas show results on an engine dyno so I'm sure thats worth some juice).

you're asking questions and trying to split hairs on theory. not a good scenario.

the fastest i've seen personally in stock/near stock form were consistently 99 and 02 cars. i don't see why one would be faster than the other.

so now...853 vs 241 - and go!

garygnu

the 01-02 cam was slightly small,but had a narrower LSA which should help with low end power.better call myth busters.
