I am wanting to do a V8 LS conversion on my 1999 S-10. I did one on my 1965 C-10 and it went great. Here is my question: I live in Illinois and I was wondering how will the swap will effect the emission testing? Right now I still have to get the truck tested when I renew the license plates. If anyone has any info on how the swap effects the emissions and/or how to get around the testing please let me know. Have a great night.
