The penciled 171 is the job number used for assembly line identification. You can expect to find it chalked on the passenger's side toe kick (possibly abbreviated "71") and on the passenger's side tranny hump under the carpet.
27 on this toe kick.
25 on this tranny hump.
For the 68-72 cars, the job number is not necessarily tied to the VIN, but for some model years you can subtract 500 from the last three digits of the VIN and get the job number. Example: your VIN ends in 671. 671 - 500 = 171. For other model years, there is no correlation.

Wow, that's interesting, I wondered what the penciled number was for.
