... the vin should be located on a little ledge right above the water pump inlet on the passenger side ... Does not even look like they ever was numbers.
All engines are stamped with an engine ID code, consisting of assembly plant code, production date and suffix code. V8 codes are stamped on a pad just forward of the right side (passenger) cylinder head. 6 cylinder engines are stamped on the passenger side of the block behind the distributor.
The engine date must precede the car build date, otherwise something is amiss.
Some engine machining operations (decking) will obliterate the engine ID.
... it's a 2 bolt main. I thought all vette engines were 4 bolts.

The last thing I noticed, it has a mount for the mechanical fuel pump with a plate over the hole. Is that on all of them? ... My guess is that they all have the fuel pump mount...
Your guess is correct. The mounting location for the mechanical fuel pump is incorporated into all of the small blocks. With fuel injection, the fuel pump moved to the tank so the mechanical location is plated off.
Be aware that the top bolt hole on the front of the block in front of the mechanical fuel pump location is open to the oil galley, and should already have a bolt inserted there to prevent oil leaks I found out the hard way when mine fell out and I was spurting oil like a cut artery. :eek
