For a born with engine, shouldn't the engine assembly code on the Protect-o-Plate match the engine pad stamp? My car was resold early and I only have the warranty POP, which does not provide much information; however, I have some early receipts that have the POP imprint. The POP imprint shows the engine code to be T0605DZ, but the engine pad shows V0605DZ. I think it's the born with engine further supported when I found the date to match and the DZ code. I didn't question the T at the time, but recently was reading that DZ engines were not assembled at Tonawanda. I have also read about typos on POPs. so that is my current assumption because I am guessing that the POPs were manually created and subject to mistakes. Any other known examples of this kind of discrepancy in the POP engine code or other explanations for what may have caused the discrepancy?
