I recently bought a 1970 70hp Chrysler motor, but of course it doesn't have an owner's manual or anything! Can someone tell me what the appropriate gas to oil mixture I should be using?

I got an old Chrysler manual. In it it says to use 24 to 1 for the first 10 hrs after prolonged periods of disuse. I'm not sure if this still applies with todays superior oils.
