All depends on the filter and how patient you are. I know with my truck, if I put 4.7L in, it will be a little over, after it all drains down, but it doesn't worry me.
I use a Quaker State QS8A filter, have been for the past two years with no problems.

Dodge+Ford = always ready
as per the manual
with new filter you need 6 quarts.
no replacement filter 5 quarts.
my trucks all read high with 6 qts and new filter but thats what the manual says along with everyone on here.

Back in the day the rule of thumb that i always used was 1 qt per cylinder but somewhere along the line that changed.
When i did an oil & filter change on my 351 last month it used 5 qts. ( It's what the owner's manual in the glove box said.)
That might be why they sell oil in 1 qt and 5 qt containers.
A five quart jug seems like an oddball size but that might be the reason for it. Maybe it's some new industry standard or something.
The safest bet when you do an oil & filter change is to refill it with five quarts and see where it reads on the dipstick before you start the engine.
If it reads a little high, run the motor and let it fill the oil filter then shut it back down.
Take another reading on the dipstick to see where you are.
If it reads right to the full mark then 5 qts was the right amount to use.

It's a Canadian thing eh!
It does allot to do with the filter I think too, my old fram vs my new bosch filter with the same amount of oil reads differently. The fram one had a higher oil reading then the bosch, same size filter but the bosch would hold more oil.
Maybe cause of the drain back valve I dunno.
