Those blocks were nowhere near crap for sure. The 010, 014 blocks are the two most desirable blocks from the old school [75 and older] that you can get due to their high nickel content.

I did get one that had been backyard honed once when I bought my '73 C-20, but that was a fluke....all the others have been very good including the current '70 block. It is a four bolt main 010 block. The builder told me I could have done much worse than to find a C-10 with a numbers matching block in it.
