Default Engine decode

I got a truck that has this motor in it. Hoping you can help decode it.
Below the head on the front is V0126XPS, nothing else.
On the back of the block I see 10125327 on the passenger side and
and on the driver side:
GM 5.7LG
SGI
A055
From what I can gather it was built in Flint, Jan 12th, not sure what the XPS is since I didn't see that on the website I was looking at. But I saw somewhere that the 10125327 is an LT1?

If there is a "327" cast in the block on the sides it is a LT1.

Sorry its been so long. Yes there is a 327 on the block. On the block right above/behind the oil filter looks like it was hand stamped 1S2174623. Does that help at all? I was hoping to find the year and what it came out of. It didn't come with anything fuel injection so I want to the the junk yard thing and find something that will work.
