Default Help determine engine year

OK guys, I just received my LS1 pullout. Engine, T56, PCM and Harness supposedly from a 2002 Firebird. I think I got screwed from asapmotors.com. Please help me determine if this is the case.
Here are the details
Block casting number - 12570592
Has EGR mounted to pass front cyl head and attaches to top of intake mani
valve cover bolts go around perimeter not center
coils each mounted individually not to a bracket
There is a date on each cylinder head of 02/07/98

After hours of research, it looks like I have a 98 engine. I've been told this is not the engine to have for lots of power especially because the PCM is harder to program. Can any of you guys shed some light on this for me. Thanks in advance guys.

Pretty sure you have a 98 motor. How having a 98 motor will limit you really depends on your goals in perspective. Seems like people on this board make it seem as though the 98 LS1's cant and have never made good power.

thats a 98 motor.any ls1 can make great power and can be tuned to accept any mods you want to do to it.but if the seller said you were getting a 02 motor then i would be pissed.

I'm more concerned with the whole package as a whole. I've heard that the 98 isn't as compatible with the tuners out there. For example, the predator works with the 99-02 cars. They may have one for the 98, but because the 99-02 predator won't work on the 98, it marks me a little nervous. What would you think a 98 pullout should cost? I paid 4,000 for the t56, engine, harness, and PCM. I think I over paid especially when they quoted me 4,000 for a 2002 firebird engine. Thanks guys.

Well, what car are you putting this motor in?

An LS1 motor is an LS1 motor. It's the PCM that makes it a 98 in this case. I don't think there are enough cam differences that you couldn't use a newer model PCM, and I am sure you can find one around. Besides, the PCM has the original vehicle's VIN in it. I am sure there is a way around that as well.

What would **** me off more is the condition of the motor, ie if I was told I was buying a low mile 2002 and got a high miles 98.

I belive the oil galleys are smaller and this is a problem if you spin the 98 motors to high also the pcm is tougher to tune due to the lack of options you can tune it that yr pcm.
As was stated before it depends on the year your putting it in.
But if you got the harness and pcm with this motor you better get some money back or send it back and get the motor you purchased.

Well, I'm putting the whole package into my Mazda RX-7 (I'm turning to the dark side). If I were to pickup a 2002 PCM, would it plug directly into the harness (and work) with the 98 harness/sensors??? I don't care about the cams, or heads, as I'm upgrading to a more radical setup, but now I'm concerened with the pistons, etc now. I have no idea how many miles are on this thing. What would the 98 setup I have be worth in your eyes. I may try to call ASAPMotors and get some money refunded and just keep the 98, but don't know if it's a good idea. You guys are great, and thanks for the thoughts so far....Keep em coming.

If you have a 98 harness you'll need to keep the 98 pcm or re pin the harness big pain but can be done.
If you are not going max effort like a solid roller spin to 8000 rpm you should be fine.
The oiling issues are only if you spin the motor super high. If you keep it around 6800 you should not have a problem. Also the pcm will not be an issue in less your going all out on a turbo or blower or a ton of n20 300+ shot.
If you are just doing a head and cam you should be fine.
Good luck

Price was a bit high for a 98 setup being a 98 i'm sure it had a bit more miles.
Also a 2002 would get you a better intake manifold (ls6) instead of the ls1. It is a great upgrade for a head and cam car. it will cost you 350 to get one of these. Maybe they could send you one of these for some of the mistakes they made. The heads are also better on a 01-02 (241) casting flow much better then the 98 (806)casting.
You can tell them all the diffrences between the years.

Why couldnt he just buy a 99+ wiring harness, ecu, and sensors to convert rather than trying to repin?

If you paid for a 2002 engine, thats what they should send you period !!!!!
Anything you have to do to compensate is going to cost you more time and money, not to mention that an older engine is likely to be in less desierable condition.

What they did is called bait and switch!
Don't let them get away with it!

Good luck I hope you get them to do the right thing for you.

The 2001/2002 does not have EGR. They should know the difference between the 98 and 2002.
Send that motor back. Have you called them yet to see what they have to say?

Yeah, I've called and they keep telling me that they sent me a 2002 engine. I think I'm gonna call my credit card company and see if they can do something. I think ASAP is more likely to comply once they find out they aren't getting paid. I'll have to see if my CC company can do anything for me.

What you need to tell the CC company is that they committed fraud by selling you one thing and saying its something else. Most CC's have fraud protection.

That should get their attention

If you have solid proof that you ordered a 2002 engine and they sent you a 1998 engine, then that is fraud for them to misrepresent their products.

All you would have to do now is have a GM dealer verify that it is not a 2002 dropout assembly.

You need a GM dealer to verify it to have solid proof. GM makes the motor so they need to verify it. Saying a well known engine builder in court doesnt cut it, but a GM rep does.
