1965 GTO engine/VIN number question
I am new at this so be patient (note first post). I bought a 1965 GTO. I have PHS papers. Someone locally told me that the engine block number and the VIN number could not be exactly matched with each other due to the numbering system used at the time. The issue is that the original engine/trans are gone so there is no way to go back, but is there any added benefit (value) to obtaining another 1965 block and installing another 2 speed auto on the column? Mine is a hard top, was blue charcoal (now weathered gold) blue interior (now musty black) 4 barrel carb. I am doing a frame off, going back to original color inside and out. Somewhere along the way it had a 4 speed installed. I am wondering if I am better off trying to go back as close to original as I can, or since the engine/trans are not original, does it really matter at this point? Either way I am going to have more in the restoration than what the car is worth, but that is just the way it is. At the same time, if possible, I would like to enhance the value too, beyond just the restoration improvements. Thank you.
