How in the HELL does my 02 have EGR
WRONG!
Per JRPs FAQ Sticky
933 97 aluminum perimeter bolt 5.7
806 97-98 aluminum perimeter bolt 5.7
853 99-00 aluminum center bolt 5.7
241 01-03 aluminum center bolt 5.7 (some late MY00 cars got 241 castings)
243 LS6 aluminum center bolt 5.7
98 Has COMPLETELY different heads than 99+ they are perimeter bolt whereas all the others are center bolt valve covers.
So if you have 806 heads you know what year LS1 you have. But if thats the case I'm fairly certain it would require a 98 PCM. (I'm not sure if they are backwards compatible but I know 98's have completely different PCM's)

also, your heads should say 241 (late 00-04 LS1 heads) on the passanger side. if they dont have a number over there, but have 843 on the drivers side it is a 98-early00 motor.

So I was looking at the emmision sticker under the hood. It shows a diagram of the cats and the air system but it does not show the egr. The door and dash vin #'s are the same. Where are the casting #'s on the head? The front of the passenger head is blank. The valve cover are center bolts with coil packs on a rail. I understand demodding a car but to change the wiring harness seems like a waste of time. Where exactly are the vin numbers stamped? Thanks for all the help everybody.

I'm sorry about your misfortune man but you really shoulda checked the car out further. Not the dealers fault. They may have not even known anything about the car. If you say the car dealer seems to have many highend cars there then thats the risk you take buying from a place like that. Hotrodders break stuff and when they do sometimes they swap in what they can find. The cars engine may have blown and the guy may have swapped in a cheap close local engine and then decided to trade it in. You never know and it isn't the dealers fault. Honestly you shoulda seen the exhaust tips right off as a sign. SS's have chrome ones i think and z28's have the wide mouth ones I know. Personally when i bought my z28 i crawled over every inch of the engine compartment for anything that looked outta place. If it was an ss then i woulda done the same and ran the vin before purchase also. Look on the bright side though being as the engine isn't a real SS then you should show no restraint in modding the HELL out of it.

i can't be much help as to why it's like that, but i did run a CarFax for you (i'm a dealer) - NO REQUESTS.
it's all clean on there, but of course - stuff can 'easily' get left out of those things.
if you want a copy man, just send me a PM

car fax reports are crap
my friend had a totaled car and it never showed up as being totaled. if you dont belive me pm me and ill give you the vin to my totaled car, it wont come up as being in an accident, and it has a 100% clear title on it even though its 2 feet shorter in the front

maybe the previous owner simply traded someone the ls6 intake for a ls1 plus some ca$h. the casting numbers would really show where to lean towards, engine swap or intake swap.
good luck

Strong possibility the car started off as a 2002 V6. The previous owner did an LS1 engine swap with wiring harness, changed the gauge cluster, listed it as a Z28 through dmv, and in addition enhanced the looks with SS hood, spoiler, wheels, and other additions to make one believe it is an SS, completely changed to match, except for the vin. From the looks, your former v6 got a promotion.

Well it is for sure a 99-00 engine. Casting # is 853 on the driver side head. I am communicating with the dealer. I really dont know why. I am sure there is nothing they will do. They offered to make an offer to buy it back, but I would be screwed on price i am sure, and I would not have a car. I am pretty upset, and really dont know what path to take. Goes to show you really have to do your homework. I was very uneducated when I bought the car. I have learned a lot since then. I was proud of myself for installing my own headers by myself. I have put extra money into the car(not much compared to some of you guys, but my money nonetheless). This pisses me off, but the only real differances are the heads and intake. I think. That and the fact I have no clue how many miles are on the engine. It is a real ss I have the cert from slp and the orginal documentation that came with the car(window sticker, and slp stuff). For what ever reason some one changed the engine. I cant prove it was the dealer, nor can I prove the dealer ever knew anything. Sold as is comes to mind. The car is loud as **** after the install. pacesetter lts into y pipe into a "borla type setup" cme out the back. so basicly for now it is straight pipe no cats no muffler. Thanks for the help guys. I let you know if anything else happens.

Silver02TA thanks for checking the carfax. Good to know it was clean.

Well that really sucks. There really isn't anything wrong with the older LS1s; the only thing that you should be concerned about is not knowing how many actual miles are on the engine. Now, if you payed a pretty penny for that car because the odometer had low miles, and all you got was a 02 car with a motor with...let's say 150K miles, you'd have a case against the dealer that sold you that car. So tell us, how many miles are on the odometer?

Sounds like it's not as bad as I was thinking. It is a real 2002 SS, just not the original engine. It is too bad that you don't know the mileage on the engine though. If it runs good I would not be all that worried about it.
Don't beat yourself up about not knowing this when you bought the car. It's just because of the stuff I have learned in the past 2 years about these cars that I knew something was not right with it. Otherwise I would not have seem anything wrong either.

Get a lawyer. You do not have to eat this. It was illegal for the dealer to sell you the car so the sale agreement is null & void. You cannot take an engine from an older vehicle and install it into a newer car. Its against the federal emissions laws.
The '01-02 engines are better. Besides the intake, they have better heads, rodbolts, oil pump. Dont let the dealership push you around. It would be much cheaper for them to give you your money back than to deal with the law.
