I have 67 that I have owned since the mid 70's. Engine is coded V02I3ME. It was a complete and untouched, stock motor that needed a rebuild when I got it. It has been out of the car and sitting under the bench since then. I recently decided to rebuild it and put it back in. Problem is that I only now noticed that it is too early for the car, which is a 07B trim tag date. Engine casting date is A297, so it is ok with the engine build date. Being a 67, it doesn't have the vin number anywhere on the block. The heads were cracked when I pulled the motor years ago, so they got tossed. I haven't dug the intake out of storage, but if it has a casting date closer to the car build date, should I assume that the engine was replaced before I got it? Or is it possible that the engine sat around that long before it was put in a car? Everything else points to the ME code being correct, so I never realized the discrepancy.
