Hey guys, new to the forum and LT motors. Im trying to identify a block. Can anyone tell me the significance of the L203 below the 5.7 stamp? It doesn't look like a normal cast #. and where could I find the casting number if this is not it?

I hope the pic works.

Look here.

I don't think the other number has any significance as far as block ID.

It looks like an Impala motor with the cast iron heads, the id number will tell for sure. You'll need to know to replace the engine harness.

I didn't look at all the pics at first, but yes, the water pump is a b-body one.
