Check to see if the vin on the dash matches the vin on the driverside door. Then I would start getting numbers off the block and look that up. It could be possible that someone had modded the car and decided to demod and only could get the ls1 manifold and egr/air pump system, so they installed that in place of the LS6 which they sold. Don't know.

If all this checks out and you owned a 2002 35th with EGR, I'd put it back on and park the car for about 20-30 years. Then contact GM and get all the information you can on the car that verifies that the engine that's in your car was the original engine. If so your car is going to be worth big money in the future. Just think of all those one-off, or factory mess-up cars you see at shows that are original and bring big money because they are 1 of 1.

You may have a big chunk of your retirement sitting in your driveway.

Get the casting numbers from the block and heads, that may give more info about the year of the motor.

yep everyone on here is tellling you the right stuff and you def need to check the casting number on the block and that will tell you the date of the motor.. where did you buy your car? at a stealership or private owner? if its a dealership im sure you can sue the hell outta them.. bc that is totally illegal if they didn't tell you everything about the car.

How true is this? Cause that is what I was thinking. I am going to check casting numbers on block. I will post them up when I do. I followed the egr wiring in the harness back to the cylinder 8 injector. I was thinking maybe somebody just put it in the loom so that it would appear to be stock. Does not appear as though they did.

Ok where are the head casting numbers? and how do you see the casting number on the back of the block.

Did you happen to buy this car in Grand Prairie in the last year or 2? I saw a "2002 LE" on a car lot that did not look right to me and had EGR. It had Z28 style tips on the CME too.

also you should find someone to scan your vehicle's pcm to figure out what year/vin is in the vehicles PCM. I agree though either someone swapped in a 99-00 motor or you have a 99-00 car that someone messed with the Vin on...at this point it could go either way. Sucks to be you right about now dude.

You bought it in Grand Prairie? You know, I have seen a few "bad ***" looking cars at one of their dealerships. Always made me wonder how they managed to get a hold of them. I have seen 3 HOSS's up there in the last year. I think that they are screwing around. You definitely need to get some hard evidence that they just bent you over.

Oh it's a nice car and an LS1. It just may not be exactly what it appears to be.

So I just called a local chevy dealer. they said the vin wasnt "burned" in to the pcm nor the was the year. He said I could possibly pull the pcm and get a part number but that may or may not work. any ideas? If someone could scan it I would pay you a reasonable fee for your time.

Sorry about your luck will350wax. Defenetly keep us up to date with what is going on with your car. The block number is located on the back on the drivers side below the head. Flashlight and a flexable mirror will work.

Definately weird, but not that big of a deal in my opinion. Would an 01-02 wiring harness have the EGR connector? It sounds like you looked and it might just be chopped in.

You might look on 35thle.com too. I think one of the moderators has data on all of the LE cars. They could probably confirm if it is or isn't an LE.

If it's not it's not the end of the world or anything. But the dealer should be at least turned into the BBB or something.

The part number of the PCM won't tell ya anything. They are the same. You may be able to talk the dealership into reading it.


Have you checked the VIN on the car yet? The PCM VIN doesn't mean much.....anyone with tuning software can change that. The VIN plate should tell you all you need to know. Either it was a 6 speed car with LS1 swapped in or a 99-00 engine/intake was put in there.

You need to check the VINs on the car - it's stamped into 2 or 3 locations on the body of the car, as well as on the engine/transmission. Make sure it matches what is on the VIN tag at the base of the windshield.

I can see someone swapping in the exhaust manifolds, EGR/hardware, and LS1 intake when de-modding a car, but I can't imagine anyone going through the trouble of swapping the engine harness out as well.

check your vin number to the RPO codes on your drivers side door VIN numbers should be the same

there is also a sticker under the hood that says "this vehicle complies to the emissions standards for the year blah blah"

its very possible that someone had a built motor in the car and when it was time to sell it they swapped out the motor for a 2000 complete with harness.

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.

I could be wrong but I thought '98 heads were the 803 casting and the 843 is 99-00.

This is probably the easiest thing to check. Even if does say 241 it doesnt mean its a '01-02 motor. My car is a 2000 that came with the 241 heads. It also had the egr intake so its definitly not a '01-'02 engine.

Id demand a complete refund. The dealer sold you a hacked car. My guess is that someone blew up the motor and sold the car cheap and someone replaced the engine with junkyard engine. Who knows, just get rid of it.
