It’s a discussion we have had on our Camaro with a few people with mixed feelings. Reason being is that the vin isn’t on the pad so the only thing that exists there is the build date and the suffix code for the trans. Grind out is also evident on the cylinder head as the wheel ate into the side of the head while it was being done. The date stamped back on the pad is 2 days prior to the NCRS shipping report said it left the factory. I’ve asked people about grind outs before and it seems to be a touchy subject for the same reasons as what is already being discussed here. When we took ownership of the car, we had assumed it been decked and someone stamped the date back on, however when we pulled the head off to see the broach marks, we started researching grind outs…

Good question!
