Ok, so I got the Valvoline VR-1 20W/50 and the Wix filter (disguised as a NAPA one) and proceeded to change the oil.
I initially put 5 quarts in and checked the dipstick without even starting the engine.
It said I was still low by about half a quart....

So.... I put another half a quart in there and call it good, still not trusting the dipstick.
Yesterday, we take the car for a nice drive to a regional show. Hotter than hell, nice people, car looked spiffy sitting up on her perch
overlooking much of the show field:

The oil pressure, according to my not-state-of-the-art "Bosch generic" gauge, bounced around 80psi pretty much
the whole time despite the heat. The car ran it's usual 180-190F temps.
Got home and popped the hood and saw evidence of some slight oil leaks around the newly-installed valve covers.
All the mounting nuts took more tightening easily. Hoping the FelPro hard-as-carp VR gaskets soften up some and
do a better job of sealing now that they've been heat cycled a few times.
I check the dipstick again and …. it STILL wants more oil!
Ok, that's it. I'm calling bullshit on this dipstick.
In the wee hours this morning, I get the brainstorm that - HEY! - maybe the dipstick tube isn't fully seated in
the block?? Maybe THAT'S why the dipstick keeps reading "short"??

Nope, reckon it is fully seated and looks to be original.
Even more research commences - you know me, I research **** to death....
and I found nothing to tell me what the hell this pan is SUPPOSED to hold, short of some kindhearted
folks here and there stating the usual "all RB's take 4 quarts plus 1 for the filter".

Pan says "699" on it plain as day. I read that it's the same as the vaunted 187 pan, but what does THAT mean?
I now know the 699 was used on '72-'73 c-bodies only, but that doesn't help much either.
The way I got oil seemingly leaking out of all sorts of places down under there scares me, too...
I got a WTB thread up right now asking if anyone has a spare stock dipstick they could part with; I am no longer
remotely interested in buying a reproduced one from anyone, given all the bad reviews I've seen online.
Can anyone definitively show me what the damn capacity of this pan is SUPPOSED to be?
Does this thing LOOK like an "added capacity" pan to anyone?
Hell, if anything, it probably holds a little LESS than it did stock, given all the dents and such on it.
Further, was it not a good idea to run 20W50 in this thing? Is what I'm seeing too MUCH pressure?
Does having too much oil in the pan actually INCREASE pressure?
My instincts are telling me to drain the damn thing, then put back ONLY 5 quarts regardless of what the damn stick
says.
Advice? Answers?
