Help determine engine year
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.

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.
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.

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

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.

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.

Send that motor back. Have you called them yet to see what they have to say?

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.
