New LS1 Owners - Newbie Tech - Incredible numbers claimed by a sponsor...

This comment was made by a supporting tuner of LS1tech in the f-body section of the corvetteforum.

My car was built towards the end of production, so GM was putting LS6's into them, just so they didn't have to make more LS1's, from what I've been told. (I've also got the build sheets, of the whole assembly process. It tells on what day what parts were done. The car took 3 days, from starting point to the time it drove off the line.) It had an LS6 block, LS6 heads, and an LS6 cam.

He's also claiming that he put down 335 rwhp/353 rwtq STOCK.

My T/A stock - 335/353 rwhp/rwtq

This info is coming from a SPONSOR of this website!

Please fill me in, is he flat out lying, or did some later f-bodies come with complete LS6's, and dyno 335rwhp stock?

My car is a very late built 02 without the LS6 block and 241 heads and it dyno'd 336/350 stock.

LS6 blocks did come in a portion of 01 and 02 cars but never 243 heads.

Actually VERY few late 02's had 243's, but I don't believe any had an LS6 cam.

Thus the debate goes on... lol Some say there were 243's and some say just the blocks. I respectfully choose to believe there were never 243s, until someone shows me some proof, which i wouldnt mind seeing!

There was a few last of the run cars that got 243 heads. I saw it with my own two eyes on a untouched car.

They put an ls6 in just so they wouldnt have to make more ls1's??? They doesnt make sense to me, seeing they made more for the gto's. OR...maybe Im jealous cause I bought a 2000. Maybe thats why you here about a few 02's running 12.9, even heard of a 12.8 right out of the box.

Personally, I also do not beleive that 243 heads ever made it onto an F-body on the assembly line. I'd have to see proof from GM to beleive this.

The LS6 block I beleive, but not the heads and definitely not the cam.

GM was still putting LS1s into '04 GTOs and '03/'04 C5s, so why would they be running out of LS1 parts in '02?

mid 01+ vette LS1s used the LS6 Block and LS6 intake manifold, but with the LS1 heads, cam, ect.

can't speak for the other LS1 cars.

Considering they still put the ls1's in the vette for 2 more years, I highly doubt they ran out, or did not want to make any ls1's. Actally I believe it was 20% of 02 cars had the ls6 block. They never came with ls6 cams. As far as heads, I have never heard of it through any reputable sorce. A local guy claimed the same thing. I went over and looked at his car and it had 241 heads. He told everyone the same story you heard about the ls6 engine. :jest: As far as the Dyno #'s you would be amazed how high the #'s can be without the correction factor and smoothing. Another board member likes to say his car pulled 350 something rwhp. I was at the Dyno day, before he played with the #'s. They were 320rwhp corrected. Still a strong car, but not 350 rwhp. He took the correction out of the graph and the smoothing, and got 353 rwhp. :jest:

Some of the blocks were LS6's. Never heard of the heads/cam being affected.

I think we can all agree;

LS6 block, yes, very possibile.

LS6 Heads/Cam, NO.

we have to find the guy who bought the very last bird or camaro and ask him, i believe the guy with the last production bird is on this website. Surely if they ran out of ls1 blocks and heads, the guy would have 243 stock heads...maybe he'll chime in

I believe hes refering to when a members thread got locked or removed because he commented or posted a question about another product.


If i remember there was also one about a ebay clutch and he wasn't 'allowed' to post how the clutch preformed or something another. :eyes:

The VERY last bird made was a red non-WS6 Trans Am, auto I think. It's owned by GM, not a private person, not for sale, and is in 100% original, un-prepared condition. Plastic on the seats, mats in the trunk, etc. They bring it out once and a while to some Pontiac sponsered car shows and the like. High Performace Pontiac said it was supposed to be a black ram air 6spd, but apparently not so.

ok maybe not VERY last but one of the last.. :jest: anyone with 2002 know their cars' build date? lets see if we can find the latest one haha

This is getting interesting boys, I want to see/hear from the latest TA too. Ive been told my GM employees that no doubt LS6 blocks but never heads/cams.

Great, so we get biased info based on "sponsor" funding to the site.

Gotta love it. Can't even get legit info on sites without someone slappin the Nazi stick in action.

What was the last build date. I know my car came off the line Late June 02 and has the LS6 block and had pretty good numbers on a corrected dyno. Problem is it was after mods so I don't know what it put down stock.

Mine came off the line in late August 02. I have the 241 heads, I'm not sure about the block. Is there a way to tell if you have the LS6 block?

Ok, I can see the LS6 blocks but not the 243 heads. After all there are a hell of a lot of Vettes out there from 2002-2004 and I have never heard once about an instance of a discovered set of 243 heads on a non Z06 Vette.

You can check the casting number but the easiest way is to look at the front of the block right underneath the pcv valve. I'll have to double check but I believe that if you have the circle pattern beneath the head you have a ls1 block and if you have the circular channel that goes down the side of the block you have the ls6.

Edit. See bottem link below. That's what I was talking about. A lot easier than trying to see the casting number.


Only value to the LS6 block is better oil channeling and tolerances. Possibly why I don't use a drop of oil. I dunno.

Yeah it's due to the extra bay windows in the block for better breathing and less disturbance of the oil or some crap. Supposedly the alloy they used for the ls6 block is stronger to make up for the thinner cylinder walls.

www.revxtreme.com is the shop that claims to have had the LS6 block, heads, and cam from the factory. Hard to believe with no proof though. He says he is going to scan build sheets. Here is a link to the thread.... http://forums.corvetteforum.com/showthread.php?t=1258057&page=3

I have to call BS on any f-bodies being built with LS6 heads. I know of at least two guys that had dealerships install LS6 heads on brand new Camaros though. If those guys aren't the original owners, that could have happened too.

If his car was built with the ls6 heads, cam, and block and he only dyno'd 335 rwhp, I wouldn't be running around bragging. That sounds really low to have all that.

Lol, thats a good point! I have heard of LS6 heads on an LS1 F-body, but it may have been what Tony said, they may have been installed at the dealer. LS6 cam? Im comfortable saying absolutely not.

seems IF this did happen, GM would still never make this choice for the reason of not wanting the Fbody capable of outperforming there flagship vehicle, the corvette.
AND if any C5 owner was able to catch wind of the fact that GM put there "corvette only" LS6 into a fbody would equal LOTS of pissed off corvette owners.

it just makes sense to me that IF more than just an LS6 block ever made its way on to a LS1 car it would have definitly been a vette or GTO in 04.....

i also say that if we could find proof of this in the later years then we would have something to talk about.

the LS1 ran from 97-04.
what are the odds that a few random 02 models, let alone fbody's got LS6 components.

seems very far-fetched.
