So if I put an 8 qt pan on my 400 how do you all go about guessing where the oil level mark would be? Are there dipsticks available for certain depth pans. Also have the same question for my transmission pan.

Boy, its hard not to insult you, but I imagine if you put 8 qts of oil in it, start it up to fill the filter, shut it off, wait 2 minutes, put the dipstick in it and yank it back out, you will have a pretty good idea of where the FULL line should be.
And, of course, FULL would be 8qts.Imagine that!

I have always been under the impression that it would show the same on the stick as always, but hold 8 quarts instead of four.
Have I been wrong about that all this time?

Maybe yes and maybe no.
I have a Milodon 7qt roadrace pan. But I only run 5qts in it. Ill bet you a dollar, you know why I would do that.So in my case, full is actually 2qts low.
Except if I go to the track. Then I fill er up. That HV pump moves a lot of oil at 7200, and those Eddies are real lazy about sending it back to the pan.So my stick has 2 holes drilled in it; full, and really FULL. Just like at thanksgiving; all the ladies are full, and all the guys.....
Heh-heh.

Don't understand why you would run 2 qts low intentionally. What then is the purpose of a larger pan?

the pan is full at the full mark on the stick. some times having a deep pan is also a way of getting the oil further from the rotating crank which lessens the windage, of course a tray and baffles help too.
Before I bolted my pan on I filled it up with fluid to the advertised amount that it was supposed to hold. Then I measured from the gasket surface down to the fluid level.
I just transferred that measurement to my dipstick. I had to shorten the tube a little bit.

I run the 7 qt road race pan and put 7qts in it. It reached the fill mark just the same as the last pan that was on it.

There are several good reasons to run a larger capacity pan. The larger capacity generally means a deeper pan with a lower sump.The number one reason to run a deeper pan is to get the oil off the crank. If the crank is beating up the oil, Its costing you power.If you free up some hp in the pan, you will have more power to propel the vehicle.
The only reason to run more oil in that pan, well one of the best reasons to run more oil in the pan, is to ensure the pick-up stays submerged in oil. Rods dont survive long without oil. So, if your pumping all the oil to the top of the engine and/or its not getting back to the pan fast enough, extra oil in the pan may save your engine from self-destructing. Of course solving your drainback issues and/or top end over-oiling,should be a priority.
These oiling issues usually only show up at higher rpms. With stock engines, the factory has it pretty well bugged out.But when you start pushing the envelope, you, the builder have to think ahead.
My little 366 only has a 230* cam in it. this size of cam usually hp peaks around 5600 give or take.This, depending on the trans ratios, requires a redline shift of around 6300 maybe a little less.But I like the sound of that little LA screaming its heart out at 7200. And the Hughes cam is still pulling pretty hard up there.So I engineered that engine to survive at that rpm, not because it needs to,but because I want it to.Im running adjustable aluminum rocker arms.They like a generous oil supply to survive street duty. So I modded the oiling system to give them what they need. Unfortunately, my Eddies seem to have lousy drainback. So I cut drainage channels in them, in an effort to get that extra top-end oil back into the pan. But with all that oil now going to the top, I had to think ahead to the rod supply. Extra oil in the pan seemed to be a good solution. Well to keep that extra oil off the crank, a deeper sump was mandated. But on a streeter, running a lowered suspension, theres not much room below the K-member,to run a deep sump.So the best solution for me was a roadrace pan, with side pockets and a 1 inch or so deeper sump.This lead to the 7qt Milodon Roadrace pan. Seems to be working, cause the al.rockers have nearly 125,000 miles on them, and have only required 2 or 3 adjustments during that time, despite running only 1/2 turn or less of lifter preload,in more than 10 years.
Hope this helps
