and, in particular, this paragraph
As the subregular and middle grades of gas came to market in 1962, the average octanes of gasolines in the U.S. now stood at 93 for regular, 99 for premium and 102 for the few super-premiums still left on the market. Those numbers would increase only slightly in the next few years to around 94 octane for regular, and 100 for premium by 1967.
The short answer to your question is that it appears that premium gas in 1964 averaged about 100 octane.

So, your car was probably designed to run gas that would be between 95 and 97 octane using the current AKI system, which is at least a point above the highest octane you can get in most regular stations, which sell either 93 or 94.
Here's a nice version of The Story of Gasoline.

Thanks for all of your help. The car was sitting ofr 25 years+, so I am in process of rebuilding carb/radiator, and dropping the gas tank to have it restored. I noticed the filler cap stated premium fuel only. The seller did not notify me of this, and I don't think he knew which 330 V-8 was in the car. When the car was unloaded from the carrier, the engine ran smooth and very quiet. Can't wait to get it on the road!!!
