Please let me know if anyone can help.

Brotherchris,
I'm also researching an old 350 block (mine's from an early '80's truck). Your casting number 3970010 was used twice: In 1968 it was given to some 327's. Then from 1969-79 it was given to 350's. If you look at the heads between the rocker arms you should see a date for when the heads were cast - this might give you a clue as to when the engine was made. (assuming the heads are original).
Try looking at this web site:http://www.mortec.com/location.htm for more info.
Hope this helps

From the book I have on casting numbers, the code TYC was used on two different 350's. One was used on 75-76 C-10 & 1500 trucks 145 HP and came with a 2BBL carb. The other was used on 78 C-20 to 3500 truck, van, bus 165 HP and came with a 4BBL carb. Hope this helps.
