It ALSO could be that the breather could be all gummed up, and or the PCV valve plugged. If the engine does not smoke out the exhaust, this might be the case.
Spend some time looking this over. You should have a PCV valve on one valve cover, going to the carb, and a breather on the other side. I don't think, that in 65, the breather was connected to the air cleaner bonnet, but rather just open.
You should have a good vacuum against your finger if you pull the pcv out of the valve cover, with engine idleing.
