Engine Cast# Date Code & Transmission ID

Hi - trying to decode engine: Cast# 3970010 Date Code K12
Is this a 350 engine for a 1973, since the date is Nov 1, 1972?

Transmission Codes: # 6261736

near this # is a circle with the following: 4 6-73

The transmission is an automatic. Is this also a TH350 for a 1973?

Thanks.
