Yep, 6qts fills my 302 and 300 with a PH8A or FL1A size filter. Probably did 5qt as comes in those size jugs for many vehicles on the road...so sounds like a lazy PO not insuring the correct level or not caring.

Huh, I'm not doubting the publication, but I don't think I've ever seen a truck V8 in a Ford that used less than six, in practice.

Me either, my dads 73 I6, and his 79 302, both 5 in and start it, almost 5.75 to get to full, even my 95 I put 6 in because 5.5 aint completely full. I remember one member putting in 7qts but had put in wrong dip stick, needed block dip stick, but somehow used oil pan one.

Six qts is what the 7.5 holds and upwards of seven, WHEN YOU ALSO CHANGE THE OIL FILTER. If oil filter is not changed it would be about 5 qts. This is not for a TC change. Strange reference for an owners manual.

Yeah, I run the full size Wix 51515 on everything, so it probably holds a quart-ish. That's still a weird way to do it. I can't imagine changing the oil without changing the filter, even if it's technically accurate that the engine itself only needs 5 in the pan.

My V10 Dodge calls for the little filter. I've always used the big Ford filter instead, (FL1a, Wix 51515, ect..)

I used the WIX 51515. I warmed up the engine then drained the engine thoroughly, removed the old filter, replaced the drain plug, oiled the gasket and replaced with the new filter, added 5 quarts, waited, then checked the level which was low, started the motor for a moment, then added the remaining quart.
Something I did notice INSIDE the fill cap was a frothy goo that I had to work at to clean out of the cap. I think I'll go have another look before dark...

I most often see that on rigs that get driven on very short trips, and never allowed to stay at operating temp for very long, it's just condensation.
