Hey guys, I have a 2000 pete with a cat motor that peterbilt says came factory with a 6nz, but I can't verify it. The sticker is gone and it's not on the ecm. I have attached what we pulled off the ecm. Its a twin v belt setup and has c-15 covers. I know it's supposed to be etched somewhere on the passenger side block but no one can tell me exactly where.
