Charlies oil pan capacity

[ruffcut]

So, without the kickout your pan is probably an 8 qt pan

If a guy put a dipstick tube and dipstick in the block and measured from the oil pan rails to the low and high Mark, you could then measure down into your pan and have a good starting point.

In a every day street/strip type car a pan without a dipstick would not be preferred. For an all out race engine it will be fine as long as you don't have any leaks. I don't have one in my Hemi street/strip car. However, I am also running a vacuum pump.

back in the day , Chrysler always recommended a deeper pan , because the hemi, stock , would pump a qt of oil at drag racing revs / Tom Hoover told us that !!

I'd use water, and run it to about an inch below the screen
Then run that amount of oil. But then, I would certainly take Doug's recommendation (DVW).

.... and a deeper pan also get the oil farther away from the crank, reducing windage losses. Ideal is more oil, farther away from crank, without losing ground clearance. Kinda hard to do with a wet sump.

Here’s an interesting tidbit that I witnessed about oil level in the pan of a running engine. At my old job we had a couple of ford 460 based compressors. These engines would auto start and run for as long as needed to build pressure so we needed to be able to do our daily checks while the engine was doing it’s thing. They had stock vehicle chassis type oil pans on them with sight tubes plus the stock dipstick. The tube was marked with the oil level that matched the full mark on the dipstick when not running, and a level while running with the correct amount of oil. The full non running mark and the full when running mark were vastly different. Non running the depth of oil was somewhere around 4”-4 1/2” from the bottom, but running was only 1 1/2”-2” from the bottom. They held 5 or 6 quarts, so due to the shape of the pan I figure there was less than 2 qts in the sump while running, so there was 3-4 qts circulating at the engines operating speed of about 2700 rpm. It surprised me at how little oil there was in the sump when running.

Obviously it would be different with a larger pan and at racing rpm, but there is a lot of oil circulating in the engine vs in the sump depending on pan volume and pump volume.
