I am not aware of a 389 HO. In '64 the cam was the same for both the four-barrel and the tri-power. I don't remember the number but it was similar to and replaced by the 067 in 1965. In 1965 and 1966 the automatic tri-power cars all had 067's, and the stick tri-power cars had 068's. The 744 came out with the 400 HO in 1967, with a Quadrajet.

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 [This message has been edited by Ed Neasham (edited 01-15-2000).] |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
