Might be worth checking a few more blocks.

If that is on thrust side I personally would not like to us that block.

Suggest filling it to within a inch or 1 1/2 to top of water passage if
I did use it.

John, I've attached the sonic check of the three 273 blocks I had sonic checked in January. The "orange" block checked worse than the "greasy" and "rusty" blocks. None of them were all they great. I think I will build a 2bbl engine with one of them, save the best for a 4bbl engine after I get my feet wet (hopefully not literally) with the 2bbl engine on building Stocker engines.
