It's on the flange of the block on the driver's side just above the oilpan. It's a number stamp that Mercury Marine stamps on at the time of engine manufacture. It would probably be very hard to see it with the engine installed, the exhaust manifold would be in the way.
Here is a pic of the driver's side of my LT5 with the driver's head removed to give you an idea where the MM stamp is at (ignore the red dots at the top, was a mistake
):

How does 3/07/1990 engine cast match with your build date?

What exactly is involved with a "MM remanufacture swap"? I don't know what the build date of my car is, is it on the build sheet or do you have to calculate it somehow?. There was no build sheet on my gas tank, however I did pull the one out of the front crossmember. Lots of it is unreadable though, I need to get a copy from the NCM.
Here is a pic of the buildsheet from the crossmember:
As for the history of my car, I do have a carfax printout (I know that doesn't tell you a whole lot) and also a bunch of service records from the early ninties. The guy I bought the car from, bought it new, so I am only the 2nd owner.
The first record that the Carfax shows is an emissions inspection report with a date of 12/30/1993. There are no records before that. The PO did mention that the car had been sitting at the dealership for awhile, so maybe that's why there's no records before '93?
