I have inherited a truck that I have little info about it.  It is a 1982 Chev C-10 Scottsdale.  It had a factory 305 in it according to the sticker.  I have reason to believe that it may have had a 350 dropped in it.  The picture I attached is of the block numbers located behind the alternator.  I know the v is the plant, the numbers stands for Oct, 9th I think.  I looked up TDF and the best I can tell it shows a 1980 350 out of a C-20.  I can't find anything on the casting numbers though.  Can anyone tell me if my suspicions are correct on the 350 or do I need to keep looking?
Thanks
