There is the issue of the needle bearings in the rocker arms...not a huge deal since the motor is 100K warranty.... read all about it here:

A few '07s with January '07 -June '07 engine build dates have had the needle bearing and rocker arm issue.

All of the LS7 engines for the Z06 are hand built at the Wixom Performance Build Center. A few of the actual engine builders post in this thread and are very helpful.

You can find out when the LS7 engine in the car you are looking at was built using the code found on the driver's side head.
Your engine number(322531701) breaks down like this:
3=gm engine
2=line 2,3=line 3
253= the day of the year
1=line 2,2=line 3
7= the calendar year
01= sequence of engine for the day
Your engine was unit number 1, assembled on line A2, Monday, September 10, 2007
Darril is with me building prototype engines now and I have told him about your post.

I would suggest that you make sure that it is stock and NEVER had the PCM flashed with an aftermarket tune. Even if it has been reflashed back to stock, they can tell and void your warrantee.
The build date is on the driver's door. Mine was built December 06 and no needle bearing problems.
I thought that only some of the 08's have the odor issue.

But would only add that the inside of the driver's door will tell you the car's build date, not the engine build date. Still glad to hear that you have no needle bearing issues.
