Just curious.........is it good shop practice to set an engine on the floor like this with all the weight on the oil pan?

I doubt very seriously that there is one cast date code that fits all brands.
The most common casting screwup on the M38 was the test run of the new 804380 blocks in Jan 1952. Although the block blueprint at Willys was already changed from 641087 to 804380 the news never made it to the foundry and the test run blocks all had 641087 cast on them.

This block was suppose to be an 804380 block!

Now Ron........me thinks you already know the answer to that question. But if you remove the words "good shop" from your question the answer might be yes.

I don't think I'd do it with mine, but whoever owns that pretty blue engine thinks it's ok!

Done it many times; doesn't seem hurt anything.

tacked to the pan...

That skid shield is a lot more then a piece then a piece of sheet metal and the oil sump on the Willys 134 series is tough enough to support the assembled engines weight with out the skid plate.
As Bob already said, "Good Shop" practice says you shouldn't but my experience over the last 50 years of wrencing on them is it doesn't hurt a thing with this Willys oil pan. There are engines I know cannot tolerate this practice.

Thanks! Still learning. Heavy gauge American steel, good stuff.
I was thinking about crushing that carefully torqued to 14-foot-pounds pan gasket by stacking 300+ pounds of motor on top of it might maybe cause some of the pan leaking I hear about?
I'm a rookie, and glad to know they can't be related..........

Rookie. That’s funny Ron.
How long have you been posting here?

An interesting set of concerns!
Torque is the preload or stretching of a fastener.
Excessive torque will dimple the pan in at the contact area of the bolt with the pan. This will actually over crush the gasket and prevent the desired tension from being achieved on that area of the gasket between the bolts.
