Liked the title says, My block is cracked in the main web it is an 99 LS1 or was.
I need to buy another block but don't know and cant seem to find the #'s to determine what block is what. I have searched to no avail. Can someone please provide a link to a way to ID blocks so I can buy the right one first try?
Iam going to post a wtb ad after I find out how to ID and get the 99 model again unless there is a better one.
Thanks for any and all help, Carl.

 

On the back of the block right under the passenger side head on the block that number identifies the block.

 

The block is in the machine shop two towns away and I was hoping someone could help Me that knows or has access to the correct numbers or tell Me another year that is good to get.
Thanks for the reply though!
Nice FD!! You will love that with an LS in it!. I have the same name on the "other forum". Carl.

 

I now have the identification numbers figured out, can anyone help Me locate a block?? I have a wtb ad in the classifieds here any other ideas or suggestions? Thanks, Carl.
