T1I05Ip 6105782
T = Tonawanda, NY plant
1I = November (I often subs for 1 in stampings)
05 = 5th day of month
IP = engine suffix code matching 1966 427/425 with a SHP (special high performance) manual transmission
6 = 1966
105782 = sequential production number, matches vin

Sorry, left that little detail out...the 'IP' matches a '66vette order code (one of the top options for '66).
Could not find anything on the 1-21-5 or PASS. I'd guess that PASS stands for "Passenger car use"
Found that HIPER and HIPERF are common stampings for both 2-bolt and 4-bolt and used in trucks and cars.
Look for a casting number 3869942 - should be located on the top left surface of the flange formed at the rear of the block for engine flywheel attachment if that flange hasn't been decked.
