I'm pretty sure that's the sump (and drain plate) I first had on my new engine.
It holds lots of oil, but also extends down about three inches from the engine's actual sump - which in my case was about two inches too much. I kept hitting it on various solid objects until, one fateful day, I encountered a manhole cover that just plain had it in for me.
It turns out that no matter how much oil a sump contains, most of it will drain out fairly quickly if one of the bolts is forcibly ripped out.
I switched to a CB thin-line that holds about 1.5 quarts and gives nearly two inches more ground clearance. The incident made me a little obsessive about ground clearance and I then had the rear suspension raised even more. I no longer have the baddest stance on the block, but my oil has since stayed inside the engine, where it does the most good.
