Engine decode
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?
