Late April to Early May on a Pontiac Plant car in that time zone.
By your invoice date of May 12

I think your current 1966 block is someone's attempt at a restamp.
Or an SR from a different car back when.

It's not factory stamping at all . But possibly haphazard stamped by a dealer tech.

Outstanding pedigree !
Black - TriPower M20 3.90
Congrats !
