the ad says these are new(not NOS) and are being made in the USA, maybe if you contact Falcon Classics they can get what you want?
~what is~ the difference from the newer Olds cams and the 59-64 ? are the bearing journals the same diameters? maybe just an oil hole drilled through? or is the difference so much that a 65+ cam can't be retro'd to work in the 62? what's the difference in the Starfire cam, higher HP?
