How to ID a block?

I'Ve been kinda wondering about my 96. Nothing from an LT1 seems to fit.
Even things like fuel pressure reg had to be from a96 LT4 to fit.

I want to ID and see it this has been replaced at some point. Just too many odd things.

There is a 3 letter code on a pad on the front of block pass side,level with where the head face sits .
Very hard to see with all the crap in the way.If OE should be one of these 2 codes.

ZXA: 350ci 300hp AT
ZXD: 350ci 330hp MT

All Block Numbers: 10125327

MT=Manual Trans, AT=Automatic Trans.

I found that pad on my engine but there is nothing there. Does that mean the engine was replaced?

odd. the pad is on the right side front of the block.

I wonder if the bottom end was replaced. If the engine requires LT4 specific parts, that's not a bad thing.
