Just a little clairfication/exounding. Pontiac gave their cams a part number, the last three numbers we use as the designation (068, 067, etc). They stamped a letter on the cam to help identify them. That said, the part numbers for the early/miiddle GTOs was:
'64 (all) 534009, same as 63/64 non HO 421's stamped C
'65-'66 Tri-power (except XS - Ram Air) 9779068, stamped S
'65-'66 4-barrel 9779067, stamped P
'66-68 Manual Ram Air/HO 9785744, Stamped H
'67 Auto non-HO or R/A 9779066, Stamped N
'67-'68 Manual non-HO or R/A 9779067 stamped P
'67-'68 Auto R/A 9779068 stamped S
This leaves the question, what did '66 R/A Autos (XS engine) get? I assume it was aslo the 744
