Thanks for the feedback, this is disappointing for sure. I am new to this subject so forgive me for asking but are you 100% certain? Could the picture be deceiving? The PO has two independent appraisals that state this car is real... They could be full of it, just trying to cover my bases here. Also what is memorex, is that a method of restamping? I did a search but only came up with threads like "Is it real or memorex"
So now assuming you are correct how can I even tell what this motor is? It drives like a real 302 but I would hate to push it to 7K RPM and blow it because it's not a DZ... Is there any way to tell without disassembling it? My hope is that the VIN and Assembly stamp are fake and that this is a real DZ motor that was just restamped to fit this car.
Based on the condition of the car and the options I still think I got a great deal I just want to be sure what it is that I actually have.
The CRG encourages intellectual debate on matters. Nothing wrong with having an opinion that differs from others as long as there are valid reasons for it. I'm not convinced yours is a re-stamp based on what I have seen.
There are valid reasons for believing the DZ stamp on your engine is not original, mainly that it does not happen to match another V1230DZ stamp. It has been long believed that all engines of a particular code built on the same day were stamped with the same stamper. Yours challenges that tenet.
Accomplishing a re-stamp would have required an virgin 618 block dated perfectly to your car. The individual would have had to know the different fonts involved and have access to them. It's a stretch to believe all that happened.
Virtually all re-stamps are performed on decked blocks. On occasion the original stamping is faintly visible. So when you get around to it, remove the alternator, wipe the pad with a cloth and some degreaser. Do not use anything abrasive. Take some more photos without the glare of the flash. If the block was in fact decked it's a re-stamp. If the factory broach marks are there, it is most likely real and we will have to re-visit our thinking on the matter.
