How much oil in a Kevko pan?

I noticed the same thing, how it only take about 4 qts for oil to pour out of the upper plug. Not sure why that is when they say it holds 5 qts. Going by the factory dipstick it holds 5 qts. (+1 for the filter) when at the full mark and that's what I run. I've thought about calling Kevin and see what he says about it, just never get around to it.

They aren't much of a deep sump but they do control the oil well. For a street and occasional strip car their ok but if it were a strip only car I'd look into something with more capacity.
