Yes, it is an 010 block with the 020 on the inside of the timing cover. It is a 4 bolt main block. I believe, I'm going to put this block back and save it for a bit. I'm now armed with some good information and have an idea of what it will take to make this an acceptable part.

The 010/020 I have, is thick enough to go 4.100" safe, IIRC the thrust walls were at least .150" @ 4.1" bore, I'm only 4.061"-4.0615"

Not all of them are though, some were just very good and some were not.

IMO, all this work needs to be done to the blocks regardless which casting number
