I am considering buying a pull out motor complete with acc, PCM, and harness. To keep it "honset", I'd like to know how to best verify the model year by looking at the motor and/or it's code. I found this thread https://ls1tech.com/forums/showthrea...fying+year+ls1 in my search, but the info only goes up to year 2000 (Z). I would appreciate info on the codes for 2001 and up. If there's another thread that covers this, then please direct me to it. A pic of where the code is located would be helpful too.

Thanks,

what year car is it out of?

 

99 -00 has 853 cast on head 01-02 has 241 cast head! Number is at front of valve cover on lower side! Maybe this will help!

 

some late MY00 cars got 241 heads.

 

98 has 806

 

Since I will be buying from a salvage dealer, I may not be able to see or verify which car it actually comes from; ergo my need for reading the code.

Guys, if I can't use the head casting number as gospel, then I'd really like to be able to read the code.

Thanks,

can you get all the codes and then come back and tell us. we can better help you that.

 

I appreciate the offer, but I'd like to be able to identify the motor on the spot. Actually, all I really need are the codes for the year of the motor, as I think the other stuff is either un-necessary, or can be identified visually....can't mistake it for a LQ4 or an LS6.

Thanks,

Yep. Mine is a 2000 and has 241 heads.

 

Read the part number on the intake.... check and see if its an ls6 model. If so... then you've got an 01-02 motor unless it was swapped. Then check the head casting number...

 

well it'd be easier if GM only used one set of pt# per year but they use multiple part numbers for the same parts often superceeding (sp) others. thats why i say it'd be easier to get the numbers first so we could help you out.

 

Well, if that's how it has to be, then I'll do what I can to get the numbers first. In the link I provided in my first post, the following:

"The tenth [character] is model year v= 97 w=98 x=99 z= 2000 I don't know what they did after that"

So I assume there is nothing similar in the 2001 and later part numbers stamped on the block?
