dipstick length and correct level

After changing the oil for perhaps only the second time in my son's 74 F100 (390 FE from a 66 Fairlane), noticed that on draining the oil, not much came out. I would say about 2.75 qts, maybe 3. But the level showed it was right at the last dot (where the Add is). I drained it, filled with 5 qts and new filter (I use the shorty version - Wix 51068, equal to the Motorcraft FL310). The level exceeds the full dot about 1/2 to 3/4 cm.

Some questions-
I have the 66 390 that was in a Fairlane. I know the guy didn't switch out the truck's oil pan with the car's, because we had to put a small hole in the right frame piece to be able to put a ratchet extension through. Also I have a plug installed instead of a bolt, but no biggy. So am wondering about my dipstick if it is not the correct one? Or did not all of the oil drain out (doubtful)? I would say most 390FE motors hold the same capacity, but it could also depend on the oil pan too?

Try a regular oil filter? Fram ph8a? I think . . motorcraft fL 1a.

What I had to do on my bronco after buying an aftermarket dipstick, I put what the manual called for in, ran the engine a few minutes to get it cycled,let it sit a.few to drain and marked.the.dipstick with a file at that level

Thanks. I absolutely have to use the shorter filter. The 66 'car' FE motor has a filter housing that lines right up with the truck's front crossmember.

That entire FL 1a doesn't even hold a qt though. So you're talking about useing ~6oz less oil with a short filter. .

I might would do some research I to that pan. Curious as to how many pans For offered, it might have not been as.cut and dry as 1car and 1 truck style.

Oil, coolant capacity Ford Thunderbird Hardtop 390 Special V-8 Cruise-O-Matic (1965 since September 1964 for North America Australia U.S.)

Tbird took 6qts. So did truck. Maybe check this site for info on a different model like your f lane
