oil filter
I have a early 70's 351 cleveland motor with stock oil filter placement and when removing the filter it was almost dry. Is it typical for this to drain into the pan after only a few hours. I changed the oil and filter...ran the truck and checked the oil level and it was right at full. 3 hours later I checked the oil level and it was a quart over. The filter is parallel to the ground as is my BB dodge and the dodge filter always leaks a lot of oil when removing. Is this common to ford engines?

Your filter wouldn't hold a full quart and wouldn't drain all of it's contents even if it was mounted gasket side down . One of the biggest reasons for having a warm engine when changing oil is to allow the cold oil to warm up and get to the pan which takes substantially longer on a cold motor . My guess is that you have oil in the lifter galleries ect that has not made it's way down to the pan when you are checking it . If you engine is stock you could research how much oil it's supposed to hold and only put that in to see how it reads after running and then left sitting .

understood BUT when removing the filter there was no oil in it. Ever other filter installed the same way on different cars(and different filters) dripped oil out all over the place and made a mess. This is what caught My attention. Plus when starting the motor and running to circulate new oil and topping the level off if needed, the dipstick reads full. In a few hours it shows a qt over, plus or minus a bit.

Strange and interesting. I've been using Motorcraft filters for many years and I've never found it to problem to make a heck of an oil mess when unscrewing a filter as they leak everywhere upon removal.

on this Ford motor there is little chance of a mess as it's fairly in the open. Now...try and remove a BB mopar filter without making a mess. Runs all over the K frame and no way to stop it except to install a remote filter assembly. Again, the lack of any oil comming out upon removal caught My attention as this is the only motor and filter I've experienced with in 56 years

Motor-craft filters have a anti-drain back valve.
So if "something" was logged in the oil passages under pressure (crud / wrong lifters) and then after the pressure deceased allowed the oil to seep past and drain down?
If so maybe (low) compressed air blown through the oil galley in different directions might show a blockage?
Or get a ghost exorcist or move away from the Bermuda triangle.
