There were both 2 bolt and four bolt 350 blocks with the casting 3970010. I have 2 four bolts and 1 two bolt in my garage. All 010 blocks had a high-nickel content and are very strong casting (both 2 and 4 bolt). I've been running one for 5 years with a 6:71 blower (1:1 drive ratio) on the street. Can't seem to blow it up even though I've tried.
Oh, and the heads didn't come with that block. I'm fairly sure the last year of the 010 block was 1972.
