Oil capacity for 1977 Argosy with 454, according to original manual

My original manual says the 454 takes 12 quarts plus another for the filter. A total of 13 quarts! This seems ridiculous since most 454s take 7-8 quarts, but that is what it says. I've attached a picture of the fluid capacities from the original manual. Any feedback would be much appreciated since this seems to defy reason. When I fill it with 13 quarts, oil pressure reads nominal and dipstick reads full.

Look again, it says pints not quarts. I just changed the oil in my 77 with a 454 and it certainly will not hold 12 quarts. It was 6 quarts

Thanks for pointing out the obvious, I could have done some damage . I've never thought of oil in pints, only quarts. I guess they thought differently in the 70s. My motor slowly burns oil, Do you think its OK to leave 8 quarts in there, or is that pushing it? What kind of tolerance is there for extra oil?

I wouldn't add more than about a pint extra at the most.
