Question 99 or 2000, its a close call.

Well, my car is the first SS of the year 2000(build #ooo1), but has an 99 owners manual in the glove box. There is no production date on the car anywhere. I am trying to order some QTP LT's as I speak. There is a differance between 98-99 and 2000 model headers. I have air tubes and an EGR valve. How do I tell what year my car REALLY IS.

Didn't only 2000s come with both AIR and EGR?

I guess thats what I am trying to ask, do 98-99 not have an EGR valve period? if they don't then problem sovled. So then I should be fine ordering them for a 2000 model, right?

Aiight, here's the dealio. 98-00 models had EGR and AIR. The 00 models have both cats bolting right up to the exhaust manifolds. on earlier models, the passenger side cat is mounted further downstream in the Y-pipe.

You guys are making this harder than it should be...look at the VIN number, count to the 10th digit from the left and if its a 'X' its a 1999...if its a 'Y' its a 2000. Simple.

Does it have cast manifolds or sheet metal ones?

I'm betting it's got the 2000 cast iron manifolds. If so, order for a 2000.

btw, it doesn't really matter if you are going with aftermarket headers. Any 98-02 headers can be used with little to no changes.

where does the EGR bolt to on the passenger side manifold? if its up front and easy to get to its a 99. if it is on the side of the manifold and looks like a bitch to get to its a 2000.

This does not mean that it definately has that year of parts, thats what I am getting at. It can be called a 2000, even at the VIN, which it does, but it could really have 99 motor parts, in which all F cars have the same VIN code for the engine

My cats bolt straight to the manifolds.

I would save all the stock parts as well...Sounds like a very cool SS to have and maybe deserves a little more homework...

Its just strange that it doesn't have a production date on it...I would maybe try to find out more history on the car..If anything just for the hell of it...

BTW i would buy the race headers with no EGR or AIR tubes. looks 10x cleaner with out all that crap under there and most people end up taking all that off and have to cap the tubes off anyways.

I totally feel ya on that, how would I go about doing that. I already called SLP and that is how I found that it was Build #ooo1. There are no stickers on the inside of the door. I have a Motortrend or Car and Driver ( i cant remember) that has a black hardtop tested for 2000. It went up against everything from a T/A to a Dakota R/T. I wish I knew how to research this car more. I really want to put headers on it though. I should be ordering them tommarrow. I just got the subframe connectors welded on last week.

I would call Chevrolet (not a dealer) customer service and see if they know of any ways to find out more about your SS...I just think how its wierd that it doesn't have any door jamb stickers...

Wierd "quirk" cars come out like this some times (Not meaning quirk as an insult)..I know on the earlier days of the old LS1.com days...there was a guy who had a silver 98' TA with FACTORY cloth seats which is very wierd considering that all LS1 TAs come with leather only.He had the build sheet to back it up as well...

The only other LS1 TA I have ever seen with cloth interior was a white one in Car and driver which was a test car...

So I wouldn't get real excited about this but,I would definately be curious.I don't think it means that your car is "extra valuable" but,to people who are reall into all this stuff and car history,she sounds like a very special gem!
