402 pan, suspect the dipstick & tube were replaced during restoration.
5 quarts in motor with filter change, spun motor over, dipstick only shows oil at bottom 1/2" of stick. During the oil change it didn't seem like I'd drained 5 out of the thing, but I goofed by not measuring that I guess.
Top of tube also seems to be rearward of what I recall, so if anyone can post a pic of unrestored/original or verified correct setup, I'd appreciate seeing that before I break out the tubing cutter.

I'm on the road right now, I can get you that measurement this weekend if someone doesn't beat me to it.

No worries, took care of it.
Sometimes having an automotive library that dates back 50 years pays off: found a few period photos and re-bent & cut the tube.
It was almost 1.5" too long.
I guess everybody's as busy dealing with snow as I've been.
