All I am saying is this.... If my owners manual says 5 quarts fill capacity that that is what I am using.... Y'all do what you want to.
A dip stick has NOTHING to do with oil capacity. If the manual says 5 quarts and you put in 7 you are 2 quarts over capacity.
If I put in 4 quarts and my dip stick reads "FULL" then the dip stick is wrong. I am not going to stop putting in oil just because the dip stick says full. I will get a new dip stick.
Once again.... y'all do what you want to..... BUT if the crank goes down into the oil it will cause a foam in the oil. When the oil is picked up, it will have AIR in it... foamy bubbles..... something about that tells me the oiling system is not what it should be.
SO.... y'all do what you want to.....
I say the proper amount of oil specified for the engine should be in it.... no MORE and definitely not less.
I have exactly the same problem and concern. Was told the engine takes 7qts. I use 20w50 with high zinc. My dipstick looked about the same as yours. I changed the oil and only put in 6qts. Still reads considerably over the high end of the dipstick. I realize being 3qts over is bad, but so is being 2qts under. I have gone less than 100 miles on it, but oil pressure is 80 when cold 60-65 when running. What @matthewq4b is saying, so far makes the most sense to me. I am going to stick to 6qts for the moment. I would rather be 1 over than 2 low.
that’s what I’m thinking. The garage that did my oil change was pretty adamant about it being safe like that. I only gave them 7 quarts so that’s all they could’ve put in. I drained some for the sake of my sanity, but it’s still a little bit over the top safe line. (See above for picture)

All Modern thin-wall casting OHV ford V8's are spec'd to run a MINIMUM of 6 quarts, with filter. There are no exceptions to this rule, 5 quarts will leave the pan almost empty during operation over 3000 rpm and will shorten the life of the engine. Ford actually did some powertrain testing in the late 70's trying to run the V8's on 5 quarts, lets just say the long-term results were not good. .
The SBC can get away with 5 quarts in their engines as the SBC has typically has a bit better drain back and does not hold as much volume in the oiling system.
4 quarts plus can be up in the engine during operation in the Fords and the higher the engine RPM the more oil that will be up in the engine circulating and draining back. This is why oil capacities in engines that are expected to be operated at higher RPMS are increased.
Overfilling by a Liter/Quart even at 6 quarts poses no risk in the Ford V8's and you will not be pounding the crank through the oil during run or startup.
But be sure to run 6 quarts in your V8 REGARDLESS what the dip stick says...

Everything you have said is dead on. Here are a couple of pics of a 351 Cleveland pan with 4 qts. and 6 qts of water in it. It's hard to see but the 4 qt. is below the baffle. With a new filter to suck up a quart and windage and drain back at 6000 rpm there is most likely only 2 qts. in the pan. Also at 6 qts. it is still 1.5 inches below the counter weights.

they put 7 quarts in. Its reading a little high on the dipstick, is this something to worry about?
Probably not. As long as the crankshaft and everything connected to it doesn't hit the oil there won't be a problem. Many engines have additional room above the designated oil level before it gets hit. After you drive it a bit, take a CLOSE look at the oil on the dipstick. If it looks normal it probably is not being hit. If it interferes with your sleep, you can always let out a little.
