agreed but i thought that was a certain lucky few

 

10% of 01s and 25% of 02s came with the ls6 blocks. Remember, this was just the block, not the engine. I don't know what this crap is about 98-99s putting down 280-290 at the wheels. Maybe the automatics do, but the manuals are still good for over 300 at the wheels regularly. Maybe a poorly broken in engine might be slightly under that mark. The only real power difference between the 98-02 ls1 f-bodies came as a result of the ls6 intake manifold introduced on the c5 and the f cars in 01, and those cars can and will dyno over 310 rwhp stock. Bear in mind though, a 98-00 car with an ls6 intake on it will make more hp than and 01 or 02, due to the better cam.

To answer the poster's original question, when you asked how much power is "under the hood" of an ls1 f-body, I would say around 350 crank hp, just like the vettes.

 

The LS2 debuted in the 2005 Corvette.
Some 02 SS cars MAY have gotten an LS6 block.

The 243 casting heads are the Z06 heads.
The 241 casting heads are the better heads.

No F-Body ever left GM with ls6 heads in it. Some of the 01s and 02s got the block, and all 01s and 02s got the intake, and that is it.

 

Yes, that is correct.

Why did you quote me?

I am trying to make sense of what you meant. Are you referring to the ls2 when you mention the head castings?

 

01-02'=best pcm(98's had more aggressive spark/timing curve, but not as good of a pcm)
98'=28.6 lb/hr injectors
99-00'=26.4 lb/hr injectors
01-02'=28.8 lb/hr injectors
98-00'=bigger cam
01-02'=smaller truck cam
01-02'=LS6 intake
00-02'=better exhaust manifolds
02' did not get any LS2 parts(LS2 was not available at the time)
01-02'=241 casting heads(slightly better flowing because they are smoother, albeit same design). with porting all LS1 casting's flow equal to each other. There is no best LS1 casting for porting. The LS6 243's are a different story, as they are a different design.

All 98-02 cars dyno within a similar range. With rare exception they all dyno 300+ besides the auto's. 98's dyno similar to the later model cars.

 

I was just wondering, does a slightly less aggressive cam coupled with a (possible) ls6 block increase the lifespan of an 01 or 02 Camaro? And are there any tricks to find out which ones got the ls6 block by looking at the VIN?

 

The LS6 block is a little better, but both are great motors and will last you a long time. I wouldn't worry about finding an LS6 block if I was you. There were few f-bodies that actually got one and would be hard to find. The LS6 block isn't all that much better anyway.

 

10% of 01s and 25% of 02s got the ls6 block, so they aren't as hard to find as you are suggesting.
They have a different number imprinted into the casting on them. I don't remember the exact number, but I sure that if you do a search here on it WS6isKing, I am sure it will come up.

 

12561168, and it's on the back of the block, driver's side, and a pain to try to see. They're easier to determine by the dull finish of the cast surfaces, and lack of the 'bullseye' marks in the notch on the head face just on front of the head on the passenger side. There are some comments about the reduced windage with these blocks (they have much larger breather windiws on the crank bearing webs) being good for a few hp, but the evidence is sketchy.

 

I've heard the #'s may even be a bit lower than those. These are rough estimates I believe. Either way it isn't exactly "easy" to find one. It's hard enough to find a car you like, in good shape, low miles, etc. Then trying to find one with a LS6 block lowers your chances of finding the car you're looking for by 75-90%! Depending on whether it's an 01 or 02 of course.

 

You're thinking about the LS6 block.

 

no **** i was agreeing with the people who were saying only a few got the LS6

What is the highest that a stock LS1 has dyno'd? A friend of mine in his stock WS6 put down 330-340 (have to check to be positive) in his 2002 model M6.
