Look here. It's called a suffix code. http://www.nastyz28.com/gm-chevy-cod...s-suffix-6.php |

Re: date stamp characters
ok what i found so far is suffix code TBG is 70' 402 CID, 310 HP
and casting number is 3969854 says 70 - 72 402 and my truck is 72' C20. so i would say it is the original engine |
