This is the only other number I could find.

 

this is what i have in my 93 book.

Iirc, the numbers should be on the drivers side of the block right by oil filter but I remember the numbers going down, not across.

 

We found one more set of numbers.

 

The heads have casting numbers of 10128374.

 

Is it a 4 bolt main?

We haven't pulled the pan yet.

 

So it is an LT1 out a 1994 car. Once we pull the oil pan and confirm if it's a 2 bolt or a 4 bolt I will know which motor it is. The ZWA means it was from an automatic transmission car... Hopefully this won't be an issue putting it into my manual car.

 

nope. block and bolt patterns are all the same.

 

374 is a 92 up head but was mostly used from 92-94. its a good head and can be ported without issue.
